When you look at the muscle force that they measure, the solids
0:07
is by far the biggest force contributor. So I think
0:09
if you're doing a thing like half a distance test,
0:12
you're getting a good measure of explosive
0:15
qualities from the solid muscle and particularly
0:17
especially when you a bentley position because
0:20
you haven't accelerated center mass,
0:22
which is a which is sorry. It's a
0:24
it has a big role left.
0:37
Welcome
0:37
to the Paci Performance Podcast.
0:40
The podcast that dives into the philosophies
0:43
ideas and practices of
0:45
some of the best practitioners in high
0:47
performance sport.
0:49
If you're a practitioner or clinician
0:52
looking to increase your knowledge around
0:54
calf, foot strength, and calf
0:56
and foot rehab, This is definitely
0:58
an episode for you. So we
1:00
reference Colin's article
1:03
on Sports Medicine a few months ago, which
1:05
got lots of traction because it
1:07
was very in-depth in terms of the assessments and
1:10
the interventions that Colin uses for
1:13
the calf and foot So we
1:15
dive into that. We have a look at the assessments.
1:17
We go that into detail with that.
1:19
Then we look at how we use the data from those
1:21
assessments. to create interventions through
1:24
a rehabilitation process or with
1:26
a performance goal at the end of it.
1:28
One thing that I found really
1:30
interesting is the talk around the
1:32
foot. So what assessments can we
1:35
do to understand more about the
1:37
foot, more about the big toe? and some
1:39
interventions off the back of it based on Colin's
1:42
experience as well.
1:43
So a really interesting episode for all
1:45
those practitioners, all those clinicians
1:47
looking to build their knowledge in this
1:49
area, and hope you get as much out
1:51
of it as I did. This

with Colin. Colin
5:10
Griffin, welcome to the PACE Performance podcast.
5:12
It's good to see you. Thank
5:14
you, Rob. Great to be on. Yes,
5:17
I've been a big, big follow through podcast for a good number
5:19
of years now. So delighted to be to
5:21
be honest and hopefully have a a good conversation.
5:24
Absolutely.
5:24
Just reminiscing that it was
5:26
nearly
5:27
no, like, nearly nine years since starting
5:29
the podcast. So Thank you very much for
5:31
that. Appreciate that. So
5:34
it's great to take you on. We're gonna use like
5:36
I've done it with a couple of people recently, actually.
5:38
Use the article that you
5:40
published on Sportsman. There's a bit of a foundation
5:42
for the chat. I will delve a little bit deeper into some
5:44
of the some of the exercises, from the
5:46
principals, and the thoughts, theory
5:49
behind behind the article
5:51
in the podcast. So we're looking forward to having little
5:53
chat, calf strength, foot strength, all the
5:55
chemicals, rehab, all chemical
5:57
stuff. So just where do you guys dive into that? Would
5:59
you
5:59
mind just giving us a bit of a a buyout
6:02
on you? Yeah,
6:03
sure. I suppose
6:05
I'd begin with the present. I worked
6:07
in the sports and service technique in Dublin. I'm
6:09
a strength technician coach by trade. And
6:12
a significant
6:12
lead for a foot and I can rehabilitation stream
6:15
in our sports medicine department. So our department
6:17
kinda works in in
6:18
sort rehab stream to different areas. So
6:21
Look, I've been working there for the last
6:24
nearly nine years, eight and a half years, and over the
6:26
time it's gone. So it's been quite a
6:28
steep learning curve. worked with some
6:30
great people as well as past and present.
6:32
And, you know, it's been been a great
6:34
environment and and that's what's made a lot of
6:37
good connections. I was telling them to work as well. And
6:39
stepping back at a a better group and in a sporting
6:41
household, both
6:43
my parents were involved in athletics, my mom
6:45
is an international runner. My dad was
6:47
more into coaching and I've been sort of things, so
6:49
that was the environment I grew up in. So from
6:51
my earliest childhood memories, we're going to watch my board.
6:53
We're gonna pay completion races. She's
6:56
quite close to Qualified Olympic Games.
6:58
Especially we actually operate on quite a high
7:00
level. There's a lot of infinite things in her time,
7:03
like climatic training, outward training
7:05
and all that. And so that was that
7:07
was a very early exposure to that. My
7:10
dad then he was director of
7:12
coaching for Alex Arden,
7:14
as it was as it's known now, back in the sixties,
7:16
early seventies, and he was team coached
7:18
for the Olympic Games in seventy two and nineteen eighty.
7:20
And then not to become president of Federation
7:23
in the early '90s. So there was plenty of coaching
7:25
manuals liner in the house, plenty of magazines, plenty
7:27
of videos, so I was kind of getting immersed in that
7:29
at the young age. So well
7:31
as being an at least, which was hard to
7:33
avoid in that environment and also a student
7:35
of the sport.
7:36
And yeah.
7:37
Look at sport with parents, an an
7:39
employer family enjoyed a quite a fulfilling
7:42
aesthetics career.
7:45
At least internationally, junior level, up to senior level,
7:47
and two Lippie games. And
7:49
I
7:49
would say, like, I wasn't the most technically gifted
7:51
at least. I had to work harder to try
7:53
and acquire technical mastery even
7:55
though I could be an an an technical event. So
7:58
And that let's let me down
7:59
give me a that's what the curiosity for human movement,
8:03
whether we're trying to start injuries, whether we're trying to
8:05
improve technical volume mechanics, And
8:07
I suppose to getting a passion for I suppose to
8:09
work I'm doing now and definitely
8:10
fortunate to work with a
8:13
lot of good practitioners, physiologists, who
8:15
are scientists my own time is that issue or or quite
8:17
helpful to me. And and
8:18
also as well as to connect to people too,
8:21
as as I as well as transition into
8:23
my my professional career.
8:24
So I retired from a league sport in
8:26
twenty thirteen, probably
8:28
having, let's
8:29
say, underachieved, but at the same time, I
8:31
had my chances and opportunities. And probably
8:34
get as much as I could to the support and to my career.
8:36
And it wasn't at this stage past stage, I had that
8:38
was other career and funding decisions to to
8:40
to
8:40
way
8:43
up. Wow.
8:46
I knew you'd competed, but why did I
8:48
not know that
8:49
you'd competed at Olympic Games?
8:52
I don't know. It's
9:00
a very old chapter in my memory at
9:03
this stage, but, yeah,
9:05
great experiences. I'm I'm look at I'm I'm very fortunate
9:07
for doubling
9:09
that I had in sports, like I did at my my
9:12
event with fifty k walk. So I did I did a
9:14
technical event. your, you
9:17
know, is judged strictly enough and
9:20
a bit like refereeing quite
9:22
subjective. And, you know, I was disqualified
9:24
actually in both Olympic Games. none
9:26
was particularly difficult because it was actually in
9:28
really good shape. I was competing for a top
9:30
sixteen position and on course for BTV and
9:32
and got my courage. red card just for the
9:35
4TK mark. So so
9:37
look all those things as well as, you know,
9:40
get me the I suppose, the curiosity and and
9:42
and the hunger to try and and understand
9:44
moving better on the standby mechanics and
9:46
try to problem solve better and as well as
9:49
what I couldn't do for myself, I hopefully
9:51
can help us with trying to do for others. important
9:53
to work with. Interesting.
9:54
So where did the interesting
9:57
lower limb come from? because that's the way you've
9:59
gone for your PhD. That's what we'll chat
10:01
around today. Why why that area particularly? Yeah.
10:04
So when I started working the clinic,
10:07
I was kind of
10:09
dealing in others with running in recent, a lot
10:11
of her running in with Darla Lorraine. So
10:13
I think from the hip and particularly the knee down to the ankle
10:15
and, of course, And we
10:17
saw a lot of calf injuries,
10:19
and not all of them were calf strain. Some of them are kind
10:22
of like exertional pain
10:23
injuries, like, initially an overload to a
10:25
muscle that has probably poor capacity. And
10:28
so another
10:29
competitor turned up and he's quite early on.
10:31
And sort
10:33
of taking a few on
10:36
and sort of
10:37
took an interest in the area, got some good outcomes,
10:39
definitely as well as realize the need to learn
10:42
a lot more about it. and over
10:44
this, as well subsequent few years, developed
10:46
a bit of an interest, research interest in it, and
10:48
developed few research questions, and
10:51
as well as to the point where I undertook a PhD
10:53
in the area and, hopefully, now coming to
10:55
the end of us in the next two months.
10:57
I spoke
10:58
to Phil Glasgow. Have
11:01
you you've come across Phil, I'm guessing? Yeah. Yeah. Not
11:03
Phil. Yeah. Yeah. Of course. thought
11:05
you must do. And he was talking about
11:07
in in the podcast that I did with him a couple weeks
11:09
ago that that this transitioning certainly
11:12
in his environment
11:13
from lots and lots of hamstring injuries 234
11:16
years ago. Obviously, lots of research in the area,
11:19
but that seems to be they their injuries
11:21
now seem to manifest in
11:23
in the calf and Achilles issue, into
11:25
calf and Achilles issues. Is that something
11:28
that you are seeing? And if
11:29
so, do you think that's did
11:32
a particular reason for that?
11:34
Yes.
11:34
I think that's what Phil was referring to the
11:37
– that's what the incidence of higher
11:39
incidents of cab injuries that seem to have
11:41
no caught up or surpassed
11:44
the the incidence of hamstring injuries in in Roby's
11:46
cooking. They are they are Roby set up. on
11:49
the national side and provincial side. I
11:51
think actually I was listening to the podcast and team had a very
11:53
relevant point about him, perhaps the
11:56
lack of exposure to what
11:59
a certain volume of running might be just predisposing
12:01
the calf to, that's
12:02
what's having poor capacity and maybe higher
12:04
risk of those type of injuries because
12:06
we know that the calf and the sole is
12:08
you know, they operate at
12:10
quite a high capacity of high proportion
12:13
of their muscle capacity or forced capacity
12:15
at even, you know, slow to moderate speeds.
12:17
And
12:18
Yeah. That's what was the
12:20
shift in the last ten years towards, you
12:23
know, high intensity for training. as
12:25
it means almost cheeky robotic system into getting
12:27
fit quite quickly and that it
12:30
just might be under exposed in
12:32
the calf, the musculoskeletal demands
12:35
of of those sports, even field sports, whether it's
12:37
a time in your face even though maybe a low percentage
12:39
of it might be high speed running or moderate speed running,
12:41
but you know, the time you feel does that up and those
12:43
lowering muscles, particularly the calf or they're always
12:45
on. So I think that
12:48
might be part of it. as
12:50
well as traditionally, the S and C programs haven't
12:52
really focused deliberately on the
12:54
on the on the the calf muscles, you know.
12:57
in terms of strengthening and developing capacity
13:00
and maybe relied on a lot maybe more employers
13:03
and order exercises to develop
13:05
that. I wish you do, but for some athletes or
13:07
players, there might be enough and they may need that little bit
13:09
of delivery exposure for six
13:11
to twelve week blocks in the preseason or
13:13
certain times in the year. So
13:16
just keep stay on this area, stay on
13:18
the calf. And
13:19
again, reference in the article,
13:21
assessments what assessments can we
13:24
do to identify whether this is an area that
13:26
needs additional
13:28
focus? Yeah.
13:30
And it was in last
13:32
couple years with that was more
13:34
easy access to forklift
13:36
technology and it's probably becoming more affordable.
13:38
It's a lot of clinics, and clubs,
13:41
and organizations, and universities. It's
13:43
probably easier notes, our standardizing CAF test, particularly
13:46
CDCAF wise metric test. So
13:48
that's one that we use. And obviously, when
13:50
we bend the knee close to ninety degrees, we're we're
13:52
isolating the solids a little bit more.
13:54
them
13:55
you know, the gas truck muscles across the knee joint.
13:57
So when you bend the knee, we're making those muscles
13:59
shorter and there and a little
14:01
bit more redundant. So
14:03
that's one way of assessing CAF
14:05
strength, particularly for the SOLACE, which again is quite important
14:08
for field sports. I'm even, you know,
14:10
it's printing where a truly acceleration priority
14:12
where the solids is a big player. And also, for this
14:14
is running as well because the solids is a big support
14:17
for the central mass.
14:19
and as I said, operator, quality capacity.
14:22
So that's probably one test that that can be standardized
14:24
across many areas. And again, there's a little bit
14:26
of instances as well as in terms of near angle
14:28
and leather the microcosmic flexion you
14:31
might set up with. And
14:32
them so that's
14:33
what's a few areas there that probably just need to be
14:35
fleshed out a bit more. then I suppose
14:38
to get a measure of total the planar flexor peak
14:40
torque or peak force. We use
14:42
anodesic heavy test lying in a prone
14:45
position, so face down, leg stretch.
14:47
at a speed of thirty degrees a second,
14:50
working from thirty degrees plant deflection to
14:52
ten twenty degrees door deflection. And
14:55
measured peak torque, and we kind of scale
14:57
at the body weight. And say
15:00
for our distance owners, we'd like to be, you know, one
15:02
hundred and sixty, one hundred and six and sixty percent valuation
15:04
above, but for Sprint
15:06
out needs to be getting close to two hundred percent body waste. We
15:08
don't get money hitting that, but that's what was from
15:10
the numbers we've collected over the years.
15:12
That's sort of the targets we try in such based
15:14
on
15:15
then One in
15:16
your app is we work with and also fully rehabilitated
15:19
app is that we've we've managed to progress up
15:21
to up to that. But, obviously, not everyone
15:23
has another dynamic manner. So you
15:26
can do the even a
15:28
a straight leg standing
15:30
straight leg isometric test for the four
15:32
spits. you know,
15:34
which is part of
15:37
some of Alex Materials work. The
15:39
challenge there, I think Alex actually kind of switched to
15:41
that way, you're actually using a block where you can
15:43
because when you stand on the force plates, it's
15:45
still a component movement. So it's hard not to involve
15:47
any extensors and hip extensors, and you don't
15:49
know how much of that is coming from the counter flexors.
15:52
So when you use block and get your
15:54
alignment right and get more leverage to the ankle,
15:57
you can probably get a better reflection
15:59
of the of the of the calf.
15:59
contribution to to
16:02
peak vertical force.
16:03
And again, as was a surrogate measure
16:05
of total counterclock attack
16:08
force, those are the two sort of stress tests
16:11
that we would look at. And then we'd also look
16:13
at developing – look at assessing capacity,
16:15
whether it's doing even the other kind of
16:17
dynamic dynamic, Stephanie, and had a
16:20
a
16:20
good test of the validated during its PhD.
16:22
We just do a twenty reps and
16:24
measure total work done as measure of cap capacity
16:27
or in a very, very basic clinical setting,
16:29
do
16:29
like a hearing rate endurance test where
16:31
you work off a Metro number one second up one
16:34
second down, trying to have consistency of heights,
16:36
consistency of tempo, good control of the rear
16:38
foot. And when either of those diminish,
16:40
you stop them. And if they can get to thirty reps before that happens,
16:42
that's a good measure of cap capacity.
16:44
the Maybe
16:45
minimum twenty five And if they're below
16:47
that, then there's probably it's probably need to work in
16:49
the capacity and use that to
16:51
to to to set a
16:53
programming. What do
16:55
you mind just just describing that? See
16:57
it's isometric test for as
16:59
for as again,
17:00
Colin? Yeah. Yeah. I mean, Yes.
17:03
So there's a there's a I have a picture
17:05
of it in in in the article. There is
17:07
yeah. But not so sure, like yeah. So we
17:09
we set we set them at the knee around
17:12
So
17:12
the knee sort of over the the shoe laces
17:16
in about I kinda go for ten, fifteen
17:18
degrees. Dorothy Flexion. I think you need some of the
17:20
Dorothy Flexion. to get a proper measure of of
17:23
peak force in the study. So it it does,
17:26
you know, you need a little bit
17:28
of length and more than time, you need to get that.
17:30
and
17:31
then have the the knee around, you know, nice
17:33
degrees, knee flexion, and
17:36
then have the base of the first metatarsal on
17:38
the block. and then just and
17:40
then we use Russia strapping to to strap an
17:42
down, so there's very little slack in the system.
17:45
So we just make sure that we we're getting a few familiarization
17:47
trials And if there's any loosening of or any
17:50
loss of tension in the ratchet, we'll just type that again.
17:52
So that when they're when do their test trials,
17:54
it's going to tighten, they're able to maintain their dossy plexus
17:56
ankle position. and we would
17:58
go for three trial three reps
18:01
at a five second maximum asymmetric
18:04
effort and take the best out of the three.
18:06
and
18:06
it's a four foot on the block with the
18:08
block. Four foot Yeah. On yeah.
18:10
On the base of the first minute charter deliveries.
18:13
the Yeah. and
18:15
then
18:15
the block is a block on fast play?
18:17
Yes.
18:17
Yeah. Exactly. Yeah. So we weigh the yeah. We weigh the
18:19
block and we weigh the force with the block on them and and
18:22
kind of bit from that.
18:23
Yeah. It's interesting because Phil
18:26
mentioned that them using this
18:29
as a as a test, as a monitoring tool,
18:32
not only for
18:33
capacity, but monitoring fatigue in
18:35
this particular area because of the rising
18:38
in Catharine Achilles issues
18:40
in in Irish route. Well, rugby is a whole, but Irish
18:42
route being is environment. So, yeah, kind
18:44
of feeds into that description as well.
18:46
Yeah.
18:47
And it and it's when you get into a floor like it's actually quite
18:49
a quick and easy task. administer, you know, you can be done
18:51
in ten minutes. And it's not that invasive, like, you, you
18:53
know, yes, you work in half a little few seconds at a
18:55
time, but the solid is a is a predominantly
18:57
Type one fibrous muscles that's going to recover quite quickly,
19:00
and you can go on a bunch of business with rest of the day. So
19:02
and I'll let I suppose, if you are in an environment like
19:04
an impression sports, where you can do that
19:06
on weekly basis or or whatever.
19:09
You know, you you can you can be a quick test in
19:11
the morning and, you know, if someone says, little
19:13
bit off where the normally are or the baseline levels are,
19:16
it might be then AAAA
19:18
flag then to to monitor or to adjust the
19:20
training goals for that given day or a week.
19:22
So we've
19:23
taken a athlete through this testing battery.
19:25
We've
19:25
identified that things are low and they should
19:27
they don't want them to be. Next stage
19:30
is obviously strengthening
19:32
that particular area. I'm guessing
19:35
that
19:35
the vast majority
19:38
of practitioners out there, if they're doing
19:40
this kind of training, it'll be gather
19:42
raises in the seat and our stand in. What
19:44
other opportunities have we got to strengthen this
19:46
particular area?
19:48
Ideally, a
19:51
slip machine or a leg press, you know, where you can really
19:53
go heavy in the car on the car for nice sliders
19:56
and be quite stable, which is kind
19:58
of hard to get that with a free bar.
20:00
or and and it's quite hard to hold a have
20:02
you done that? If you wanna go really, really heavy.
20:05
So as far as if you have access to to those to
20:07
the logic can do, you know, you can do quite heavy
20:09
concentric, eccentric, or go heavy isometric,
20:12
the
20:12
shorter repeated holes, or you can go,
20:14
like, your your super max super maximum
20:16
eccentric. But again, you really you
20:18
need your your leg press and or
20:20
or submitting for that. But
20:23
if if someone can give a low baseline, you
20:25
know, we just do some basic stuff maybe like set
20:27
up eight to twelve, four
20:30
set to eight to twelve reps, you know, with a
20:32
two rep in reserve sort of
20:35
loading guide,
20:37
you know, just work the captive to take. They're gonna get
20:39
they're gonna get better with without any of the first start, and then
20:41
it's where do you go next?
20:42
and that might definitely should develop cap capacity.
20:45
Sometimes, again, you like to pick up
20:47
this visually. There might be luck in
20:50
It might have some actual fleet to either the
20:52
medium or natural gas truck on one side or both
20:54
sides. Or there might be there
20:56
could be natural fetal medial gastric and
20:58
one side and the lateral and the other side have a very few cases of that.
21:00
So you can benefit from position to try and
21:03
bias those muscles, muscles, muscles, muscles
21:05
heads. and workers
21:08
to fatigue and into lengths to try and get those hypertrophy
21:11
changes. And that's what's benefit the
21:13
strength a bit more. across
21:14
all three.
21:16
them So,
21:17
yeah, there will be the that's
21:19
what the main
21:21
the main exercise types.
21:24
Again,
21:25
if we have to target the solace, yeah,
21:27
we do some isolated stuff with an event. So either
21:29
very, very heavy kettlebell else
21:31
kit machine or ideally, if you got to see the cap machine,
21:33
you can go really heavy and be quite stable. And
21:36
again, with the sword, it's given the the
21:38
physiology of the muscle, you know, you
21:40
can still make good good strength changes and
21:43
even work in turn during soft motor load. So
21:45
you can still if you just make the muscle tired, it's going
21:47
to get stronger anyway. to a point. And then
21:49
it's like, you know, you might get to point then where you hit a ceiling
21:51
where you may need to go really really heavy for for
21:53
for low volume to to increase
21:55
the sports capacity even further.
21:58
But it just depends. Come on.
22:00
No. You're okay. No. You're
22:01
okay. No. I'm just saying use your your tests and
22:03
your straight leg and your bent knee, your your seated
22:05
and
22:06
half tests to you know, if you see
22:08
the shaft test, it's quite good in proportion
22:10
to your straight leg one or then, we might need to worry too much
22:12
with the solace. unless maybe in field sports
22:15
field sports where acceleration is quite important, and you are
22:17
going to use a solid little bit more in isolation, particularly
22:20
in the air leak to mid stance. of an acceleration or
22:22
a jump or horizontal some sort of horizontal effort.
22:25
And I think it's useful to to do that and untrain
22:27
it, as I mentioned, they together in synergies with the folks
22:29
and and and the hip extension. say
22:31
for distance owner and, you
22:33
know, if if the source is quite good and you test it,
22:35
and there's maybe room to improve their overall cap
22:37
strength, but then we just go straight like and
22:40
keep it simple because, again, time and energy
22:42
resources are going to be valuable to that. Well, most athletes,
22:44
but particularly endurance athletes when your your role is gonna
22:46
be tired anyway no matter. when you try doing
22:49
FMC rehab session. We'll
22:50
get on to the fight in a second. But just one last thing.
22:53
Would you be looking for a particular ratio?
22:55
between
22:55
this i the
22:57
isolated Soliris and
22:59
the general
23:01
calf complex test.
23:03
Yeah. It's hard too because there's a lot in
23:06
our in in our clinic, we're comparing
23:08
a C just you'd be
23:09
comparing a C to capitalize metric with a
23:11
with a straight leg
23:14
is a kinetic test. So in
23:16
fact, as well as the true coincidence, the number
23:18
is actually similar. We look for about for
23:20
just wanted to get at least I would even say now,
23:22
like, then we test a lot more and and we're
23:25
more more robust with our protocols getting
23:27
higher numbers now because they're more state of those conditions. So we're
23:29
seeing more people hit twice body weight and
23:31
more people and and maybe more sprint or exclusive
23:33
at least getting, you know, two point two times body weight.
23:36
So the article would have said by them, one point six
23:38
maybe twice body weight for this is an and
23:40
and maybe sprint on these respectively, but now we'll
23:42
be kinda thinking maybe one body weight
23:44
for this is an owner. who wants to create a decent level
23:46
maybe two point two in a build for your
23:48
your sprinter that teacher field support player.
23:51
the And so
23:52
It's hard to say that the proportion when
23:54
you're when you're comparing an isometric with an isoch magnetic
23:56
test. So
23:58
but again, for the isoch magnetic test,
24:01
straight leg. We're
24:02
looking at, you know,
24:03
one hundred percent six percent body weight
24:05
for your distance at least and maybe close to two hundred
24:07
percent body weight for our exposure
24:10
athletes. And then we're also able to
24:12
run a a code to
24:14
look at torque at different ranges. So someone might might
24:16
have good peak torque. But the main biggest
24:18
symmetries in either slightly kind of
24:20
flexed angles or slightly closer flexed angles, and
24:22
we can
24:23
focus on on on as well as joint
24:25
angle specific. strength changes
24:27
based on that? I don't
24:29
want to break it down to my level, but I'm sure there's
24:31
people out there. Just explain explain that a little
24:33
bit more for us. The pig talk?
24:35
Yeah. So
24:39
yeah. So
24:39
basically, like, it's like the turning force. You
24:41
you're you're you're producing. So it takes into account
24:43
the the the the the the the moment
24:45
term. So as well as the
24:47
Porsche producing. So we
24:49
scale peak torque to body weight.
24:52
So we divided the torque and you can be despite your
24:54
body weight. So and again, we're seeing good
24:56
numbers in the sort of high hundreds, so one
24:58
hundred and fifty to two hundred percent body weight across
25:00
the board. we just kind of break it down to the more
25:02
to sprint athletes and if you feel it's more
25:04
players versus your distance runners.
25:06
the Again,
25:07
we we do see there's a hybrid of
25:09
you know, we see some people you'd expect big numbers
25:11
from coming in as maybe hundred and twenty percent body weight
25:13
and maybe skinny distance from coming in across
25:15
a two hundred percent body weight. So there's a bit of hybrid
25:18
as well. But anyway,
25:20
So we measure peak torque, which
25:22
usually happens in in slight length. So it usually happens somewhere
25:25
between zero degrees neutral light because it maybe
25:27
it's between that and and maybe ten degrees torque
25:29
reflection. Obviously, you need a bit of length to produce
25:31
your peak force or peak torque. And then
25:33
we measure torque at twenty degrees counterflexion
25:36
and ten degrees towards the flexion. So particularly
25:38
for someone who's at an acute lens rupture where they're
25:40
going to be weak in an in an range counterflexion, we
25:43
see big deficits there, and it takes a long time
25:45
to to to address
25:47
and and reverse, and that's what we can probably
25:49
only get so far with that. otherwise,
25:51
you might be someone who's quite weak in a more Dorothy
25:54
Flex angles. So tend to be Dorothy Flexion,
25:56
there might be twenty percent difference. You know, the peak torque
25:58
might look symmetrical. So we can use
25:59
that false findings to
26:02
get someone if it's if it's an inter range counterreflection
26:04
deficit, do some inter range isometric work.
26:07
them and
26:08
load them there to train strengthen in that area,
26:10
or if it's a door reflection, a
26:13
door reflex angle depth test. work
26:16
them into into into into a service
26:18
centric loading scheme
26:20
or else do some long length isometric calls
26:22
to to get them stronger at that angle? I
26:24
hope that makes sense. Yeah.
26:27
I'm following. I'm I'm I'm I'm I think I'm following.
26:30
No. Thanks, mate. Appreciate that. So
26:33
you mentioned foot strength. think this is a really interested
26:35
area.
26:37
How are we assessing whether
26:39
we need to isolate or have
26:41
that isolated type of training
26:43
in our program? Or
26:46
should it be a dashboard even
26:48
without any assessment?
26:50
Yeah. No. I mean, it is quite important and
26:52
it's not something that has been done traditionally
26:54
outside of, say, it's an electronic environment.
26:57
So it's not something that's that's that's
26:59
what's typically done in S and C program.
27:02
Obviously, I see a lot of fish. And
27:04
look, mean, I've I've there's a lot of there's
27:07
a lot of there's a lot of good partitions that I never
27:09
quit and I specialize in food area that
27:11
I've pointed it as often, you know, so we
27:13
can really get can we kind of talk back and
27:15
forth as well as a good ideas can emerge
27:17
from that. So Yes. What
27:19
I've done is developed
27:21
test with a handheld dynamometer
27:24
where if you
27:26
test
27:28
them
27:29
in with a slight Dorsey flex
27:31
Ankal angle
27:32
and Dorsey flexion of the first MTP
27:35
joint to the big toe joint to the new lift the big toe
27:37
up. So there are a long length, you're getting
27:39
a measure of their flex releases longest, which is quite
27:41
a one of the important extrinsic foot
27:43
muscles that has a role to play in terms
27:45
of a toe off
27:47
the And then
27:49
we would do
27:50
the same thing with more of a plantarflex angle
27:53
to get a measure of the intrinsic foot muscle and
27:55
so we're making the flexibility as long as short and
27:57
a little bit insufficient. So we're getting more isolated
27:59
measure of the intrinsic
27:59
foot muscles, which are actually quite important. And
28:02
they have big role to play in coordination with the force.
28:04
to stiffen the foot at the right time for
28:06
a proportionate toe off, you know, especially
28:08
for acceleration for jumping, you know, with
28:11
a particularly the
28:13
most of the cost of BIGtoken are – have
28:15
quite a significant – small but significant
28:17
contribution to those type of – to performance
28:19
of them.
28:20
in sprint and jumping and
28:23
push off positions.
28:25
So there's three key muscles across
28:27
the big toe joint here. Your flexor raises gravis,
28:29
your adductor. and
28:30
add Dr. Helixis, which
28:33
are, you know, as the purposes go there, they're quite
28:35
big volume and a big physiological area.
28:37
So when we measure top
28:39
flexor strength we're getting measured up up the forescape
28:41
output of those muscles in particular. So
28:43
let's get to a quick break in this chart with
28:45
Colin Hoping Joint Power one. So hope
28:47
in part two, we discussed development reactive
28:49
strength during the return
28:52
to play process and developing explosive
28:55
strength during the return to play
28:57
process? How can we assess
28:59
if they need to
29:01
be if they don't really need to be improved? And
29:03
how can we obviously go about with that.
29:05
So a really interesting part too, coming up.

31:11
now back to the episode with Colin.
31:14
It is something that you see pop up every now
31:16
and again on social media. And it gets
31:18
a lot of It normally gets a lot of hype
31:21
because it's relatively novel.
31:23
People don't you don't see it a lot. But
31:25
should people given
31:27
the time pressures of
31:30
people like yourself, pre-two
31:32
thousand thirteen, Colin, with
31:34
with training teams what athletes who
31:37
are getting a minimum time in the in the gym
31:39
to develop. all these different things. But
31:41
should do
31:42
you, in your opinion, should practitioners be
31:44
focusing on this particular area?
31:48
more than that?
31:50
Yes. At least, you know, a screen version
31:52
of someone is making that area and they're a history of lord
31:54
and injuries. You know, I think it's an obvious law hanging
31:57
fruit to try and address. You know,
31:59
if you've had history
31:59
of recurrent sports or ankle injuries or
32:02
even calf injuries,
32:03
I think it's quite important to reach
32:05
it to to to look at. It doesn't
32:07
take that long to a set that you can even, you know, if you're, you
32:09
know, if you have enough experience, turning experience behind
32:11
you or even the experience, you can get a manual feel of
32:13
the toll factor strength. Another time is just muscle
32:15
inhibition. They are those muscles are quite prone
32:17
to inhibition for different reasons.
32:19
You
32:19
the
32:20
know? So oftentimes, I just build
32:23
in some puts foot exercises, more of an activation.
32:25
It's a warm up. So you've got better
32:27
contribution of those muscles in in those bigger sort
32:29
of comfort movements.
32:30
them sometimes
32:32
you might might use your muscle to
32:34
reinstallation to to try and increase
32:36
their conditions of those muscles.
32:39
yeah, look, I think it's just been an overlooked area
32:41
and as well as it's starting to with the help
32:43
of some good resources come out of a a couple of
32:46
labs across the world, particularly
32:50
in Queensland, Australia, New Kelly, and his team
32:52
have done a lot of good work on foot research. And
32:54
and this was Traditionally, you
32:57
know,
32:57
we would have always thought that's,
32:59
what we
32:59
call, the windlass mechanism. So when you dorsey touched the
33:01
big toe, that stiffens the erection, stiffens the foot.
33:03
So it's more of a
33:05
you know, it has to be stiffened.
33:08
Of
33:08
course, I think, you know, with the
33:10
suppose that they
33:12
That's what the emerging research from from the
33:15
group I mentioned. You
33:17
know, the actual court the activation
33:19
of the footballers are probably more important or probably
33:21
the big players in terms sticking the foot of the right time,
33:23
projecting and and so off. And when
33:25
when less mechanism is is is is certainly
33:27
because of all, but it's probably not there. It's not the
33:29
deal breaker. So definitely
33:31
important that we have good foot strength and been able to
33:34
activate it at the right time during the
33:36
gets, like, particularly as we as we go to tow
33:38
off. because
33:39
I think JB. JB McRinn's got
33:41
a PhD student or a couple of
33:43
PhD students in this area as well. Yeah.
33:45
Yeah. Roman Turlan. Yeah. We we actually got
33:47
ready to watch it for him. He has some really good
33:49
work in the next couple of years when he gets
33:51
to work later stage at a PhD. I'm
33:53
testing the life out of him for for
33:55
an hour on this area. He's gonna think he's gonna
33:57
point out that in couple of months.
33:59
So
33:59
yeah. We're we're looking forward to that.
34:02
I think it's a super interesting area. So we've
34:04
gone through that assessment how
34:06
are we training it? Yeah.
34:08
I mean, have you simply go to, like, just
34:10
doing some Bandwidth, just a big toe
34:13
curls. just
34:14
getting the foot set up with the big toe joint
34:16
on the block and the rest of the toe hanging off it.
34:19
And maybe bringing it to a little bit
34:21
of plant reflection, so you're taking out the contribution
34:23
from the tip be absent anterior or anterior
34:25
should muscle.
34:26
the And
34:27
you can, you know, start up with with the foot flush just
34:30
with the knee sort of sitting behind the ankle to be slightly hyper
34:32
flexed. And
34:33
then you can actually just do an active hearing aid
34:35
to really activate or maximize the the activation
34:37
of other foot and gelling muscles. And you wanna feel like a
34:39
a burning or a manifestation of the arch
34:42
So we do that more so as an
34:44
activation exercise. But, like, when
34:46
when you're doing single encafrases, particularly
34:49
with shoes off ideally, at
34:52
that sort of position. If you do lift a shot, it's a
34:54
vertical on the top, you know, you're you're getting good recruitment
34:56
with the foot muscles anyway and also
34:58
tip post and and your peroneal. So you're getting everything
35:00
in that that one lift. So If someone is limited
35:02
in that in that particular movement or that particular
35:05
position, we just
35:05
work back from that. What's limiting factor? Is it the
35:08
lack of foot strength of That's not allowing them
35:10
to be stable there.
35:11
And if it is, we just we bring in those stated
35:13
exercises to
35:14
to support them to to get that point.
35:16
But, look,
35:17
well, you wanna get the point where that
35:19
can get
35:19
a lot out of as
35:21
few exercises as possible, you know, especially in the busy
35:23
part of the season. So last thing someone
35:25
to do is spend an hour and a half or two hours, you know, doing a
35:27
whole lot of rehab exercises when there's what
35:29
are demand and the time and under energy
35:32
resources?
35:33
Gas. So for someone that's quite
35:35
well versed in this area and speaking to a lot
35:37
of people, in terms of the groups that we've mentioned
35:39
JV in the the Queensland,
35:41
did you say? Yeah. Yeah. Yeah.
35:44
What what is what do you think is going down the line for
35:46
this particular area? In
35:48
terms of research?
35:49
Yeah.
35:52
No.
35:52
I think I think what's come up in the last few years, I mean, there's
35:54
been been several papers since twenty fourteen
35:57
from Luke Kelly's group that are really supposed to
35:59
change people's thinking around this area. So
36:01
I think there's a lot already done. as
36:04
well as just maybe
36:06
being a bit cleaner or tighter with some of our ways
36:08
of assessing foot strength
36:09
and maybe coming up with some sort of solution with a
36:11
with a force place or a strain gauge where you can do
36:13
it properly.
36:14
you know, Han has done monitor. If
36:16
I'm
36:16
doing it myself all the time, I'm probably
36:18
confident in my own reliability. But as soon as I see what
36:20
I was doing, it might be very reliable. So if
36:22
that's why it can be hard to compare numbers.
36:24
the So maybe
36:25
having some sort of a, you know, a
36:28
a cleaner solution might might be better. And then as
36:30
well just being being a bit more creative with some of our exercises
36:32
to target certain muscles in the foot.
36:35
And I still feel like I have a lot more
36:37
need to learn about the area. I'm only
36:39
discretion
36:39
service?
36:41
In the in the article, just moving on
36:43
from the the footsteps in the Eldar, I think that's
36:45
super super interesting. And
36:48
looking
36:48
forward to getting a piece
36:50
on spots with the buy. But
36:53
back
36:53
to the rehab, developing
36:54
reactive strength during
36:57
the
36:57
return to play process. Interesting
36:59
for a second half
37:02
of the article that you wrote, focus
37:04
on this area and then develop an explosive strength
37:07
again during that pretend supply process.
37:10
So the reactive strength first,
37:12
moving through a rehab,
37:15
how can we understand how
37:17
much emphasis we need to put on
37:19
this particular phrase during a particular rehab?
37:22
so we can spend the time
37:24
or or
37:25
take the box and kind of move on. Is there
37:27
any, again, move back to the assessments? Is there any
37:29
assessments that you would do to
37:31
get help you guide whether you
37:33
need to spend that time on this particular
37:35
area in terms of reactive strength? Yes.
37:38
Well, look, I think every at least
37:41
probably the spent time on this and probably
37:43
should be the mainstay of any
37:45
sport involves running or somewhat of
37:47
impact or reactivity, it
37:49
should be nearly a I mean, instead of the
37:51
program. But in rehab, I think it's a key link between
37:53
your your your your gym base. We have stuff on your your
37:55
return to sports. another feeling on the tracker
37:58
on the road.
37:58
Exposing
37:59
the Boston unit to those high, as
38:03
well loading rate demands,
38:05
you
38:05
know, the the the the the the fast stretch
38:07
that the killer ton has to has to accommodate and
38:09
the ability to coordinate run run the ankle and
38:11
knee and the hip quite quickly, you can react to it
38:13
for a contact.
38:14
So yeah, it's quite important. You know,
38:16
we talk a lot about rate of force development,
38:19
early versus late phase rate of force development and more
38:21
sports where the reactions evolve. you know, the
38:23
earlier early phase, which is, like, how much,
38:25
you know, the biggest change in force in those first
38:28
fifty to one hundred milliseconds, and it's
38:30
quite important. And, you know, you're gonna you
38:32
pre activate before you hit the ground is actually quite important.
38:34
the So you're
38:35
relying a lot on pre activation of the lower
38:37
leg muscles and the elastic properties
38:40
of the of the kind of tenant in particular. So
38:43
reactor strength is is closely linked to that.
38:45
Yes. I think it is quite
38:47
important. And it
38:49
was just how you go about programming because, you
38:51
know, you you you take different classes of athletes and
38:53
they all got different we have to spend profiles.
38:55
Some are more like to use more ground and maybe spend
38:58
a bit longer on how to get their impulse to get good jump
39:00
fight for them. They're quick and springy. And maybe
39:02
maybe you might need to try and get a bit higher with that
39:04
same sort of you
39:05
know, short content time, and then
39:06
you gotta force that a bit in between.
39:08
You know, and then it's what you work the spectrum
39:10
of, you know, short
39:13
contact sources, maybe slightly longer
39:15
contacts, getting more impulse, and maybe work in the
39:17
contracted properties of the muscles a little bit more.
39:19
And then maybe you know, so as
39:21
well as as I mentioned in the article and and again,
39:23
purely from experience
39:24
and as well as other people who have done a lot of pioneering
39:27
work in this area and some of them you whom you've had on
39:29
on on your podcast. know, starting off with
39:31
just some basic coordination patterns and, you
39:33
know, and I have pushed a few exercises from from different
39:35
people as you do, but, like, just doing
39:38
basic workshops really like the, as I mentioned, the
39:40
the rudimentary that
39:41
I'll test and and have have
39:44
have used and boost it
39:46
boost Schneider.
39:49
I really
39:49
like that. By the way, just to try and get
39:51
some basic coordination patterns go on, particularly people who are
39:53
not as experienced at play metrics, just
39:55
getting their alignment between Ekinli and hip and shoulders.
39:58
minimize the need the need better
39:59
contact.
40:01
Trying to get the active door suppression when
40:03
they cut off the ground and
40:04
then progressing on the single leg and trying to keep
40:06
those qualities going and then you've got a bit
40:08
of a background behind you and it's it's, you know, where you go
40:10
the next, you know, de
40:11
intensified or de add
40:13
more more challenges
40:15
or more complexity to it or or go a bit
40:17
more volume or capacity work.
40:19
the
40:20
And, yes, so, like, you
40:22
were going to hear your job jumps.
40:25
hurdle hops. And then, particularly
40:26
for calf and Achilles injuries or ankle injuries in
40:28
general, I'd I'd like to bring in, like, in sign hopping where
40:30
to talk of steps in in a stadium or a
40:32
top up a header and interline where you really
40:34
kind of have
40:36
to concord it on the end a little better. And
40:38
you're really sort of
40:39
working on the on the contractor
40:41
machinery of your craft vessels as well. So
40:44
I'm trying to get back to those craft engines. I think
40:46
the MX forged is quite useful.
40:48
the supposed
40:49
to minimize the risk them breaking down again
40:51
when they get back running at those sort
40:53
of moderate high volumes again. What
40:56
kind of athlete would you call in Were
40:58
you in the spend a little more time on the ground
41:00
to get the high? Or
41:01
were you more reactive? I
41:03
was needed, so it's all good. Well,
41:06
I'm as race worker, so I I never left a
41:08
ground. I'm
41:10
really only figuring out now in the last ten years.
41:15
Yes.
41:17
No. But as a transition, I don't know, like, I've
41:19
been running for the last, whatever since I retired from
41:21
Reswork and I've been running now and particularly for
41:23
longer distances and
41:25
then
41:26
Yeah. So, actually, a very funny story.
41:28
One sorry to sorry to say to our team much. I was over in in
41:30
in monocor for a conference back in
41:32
twenty seventeen at the ISC conference. And I was like, extending
41:34
at least just begun working with JPMorgan.
41:36
That's my he's my PhD supervisor. So
41:39
staying in in the central room and
41:41
on the prom night one morning, person just come up
41:43
and come in the car, you know, give me a bit a beef and
41:45
I looked around at the JV. And he was actually driving
41:47
to monika or to monika to the conference, and we met
41:49
Afrezza. He was, yeah, you know, I promise you because
41:51
you run like a race speaker. Obviously,
41:57
that's a good thing in his Yeah.
41:59
But that was really
41:59
it. But I've probably got a little bit puncture since then, but
42:02
I'm yeah. Yeah.
42:03
Yeah. Well I didn't I didn't realize was
42:05
What? Remember did actually when I think about it?
42:07
He was your PhD supervisor.
42:09
He is. Yeah. Yeah. Yeah. Yeah. Yeah.
42:12
because I'm I'm registered to University
42:14
of Kotuzor. which is,
42:16
like, a doctor school that I think takes in University
42:19
of Nice and Marseille.
42:21
So yeah. So JV is my supervisor
42:23
a lot of his you can move back to University
42:25
of Sanofi at the end since then, but that doesn't
42:27
change. Yeah. It
42:29
doesn't change things for me. But yeah.
42:31
How many
42:31
times you've been out there?
42:33
hey Maybe
42:35
once a twice a year, pre pandemic, whereas
42:37
now we're also able to manage things remotely. The
42:39
only only work is done in double only direct action is
42:41
done in clinic. So
42:43
if you guys then can be done through through Zoom or whatever.
42:45
So I'm hoping next time I'm back there would be for my
42:47
my PhD defense and hopefully
42:49
before the end of year. It's beautiful
42:51
out there right now. Yeah. It's gonna
42:52
be part of the country. Yeah. It's a
42:55
really nice special summer. Oh, yeah.
42:57
Absolutely. So explosive
42:59
strength, Moving
43:00
on from reactive strength to explosive strength,
43:02
again, something you mentioned later in the article.
43:06
Assessment
43:06
during the return to play process,
43:08
how much time we need to spend on this? are
43:10
we just ticking the box? What assessments
43:12
would you run your athletes through
43:14
to
43:14
guide this next part of the return to play process?
43:18
Yeah. I I think even as simple
43:20
as saying, like, hopper distance because, you
43:22
know,
43:23
we we know from some of the paper that came out of a group in
43:26
Aspen Tower, but in the last two years
43:28
and is more focused on
43:30
the
43:33
the usefulness or lack of for using
43:35
us, I think, like, half a distance in ACL rehab,
43:38
particularly
43:38
during the proposal phase, because there's probably
43:41
a lot less knee contribution the proposal phase. A
43:43
lot more, maybe during the landing phase, so the need is more of
43:45
an absorber. But from that,
43:47
when they looked at the joint work contribution,
43:50
that's what the anchor hitler contributed the most
43:52
to to the proposal phase
43:54
of other horizontal app. When you look at the muscle
43:56
force that they measure, the solids is, like, far the biggest
43:58
force contributor. So think if you're doing a thing
44:00
like hopper distance test, you're
44:02
getting a good measure of explosive
44:06
qualities from the solid muscle and particularly
44:08
especially in the movement bendy position. could
44:10
you have an accelerated center mass,
44:12
which is a – sorry, is the
44:14
– that
44:15
has a big role in that.
44:16
So that's probably one way.
44:19
probably
44:19
the simplest way to do it
44:21
as an assessment. As
44:23
part
44:23
of my PhD work, I've tested the reliability and
44:26
ended up with some of the biomechanic features of a of a thing
44:28
like horizontal rebound. So it's like a that's what
44:30
the double single, like, hubs. So we hop out on the forest
44:32
bit rebound for distance. And we
44:34
looked lot of variables, like,
44:36
And we we we actually looked for I suppose
44:38
trying to recall is that, we somewhat
44:40
kind of touched on it before. I'm not saying we didn't pioneer
44:42
this, but just trying to maybe strength
44:43
in the case, we're using horizontal reactive strength
44:46
index as
44:47
horizontal alternative to a vertical
44:49
reactive
44:49
strength index measuring rebound, dividing
44:51
rebound distance by the contact time
44:53
them So
44:55
we looked at that and
44:58
we looked at us like
45:00
vertical and joint stiffness we look
45:02
to just hit the ankle joint power
45:04
and joint work and all and
45:06
the joint angle changes. And similar
45:08
to the hopper distance paper in Aspirator,
45:11
the ankle,
45:13
m you know,
45:14
had the ankle and slightly slightly
45:16
lesser degree, the hip had had the biggest contribution
45:18
to to joint work
45:20
and power. And then he obviously
45:22
had a lower contribution, but it was it had
45:25
highest it was the one joint that highest higher stiffness
45:27
than San Diego. or
45:28
the hip.
45:30
So
45:30
yeah. Any sort of horizontal
45:34
jump we'll give you good measure
45:36
of low limb exposure to some qualities. And
45:38
I mean, you will get from Vertical too, like, sort of something
45:40
like a Scott jump or And currently
45:43
with junk, you're probably getting a good measure of exposure
45:45
quality as well from the low
45:47
limit, particularly the calf. So
45:48
though and
45:51
Yeah.
45:51
I think either either or. I mean, there might be
45:53
some logic using
45:55
maybe one vertical or maybe one horizontal one depending
45:57
on the on the sport you're working with.
45:59
just the horizontal RSI
46:01
So hopping onto the fast play
46:04
and going for distance on the -- Yeah. --
46:06
on the rebound. Okay.
46:07
Yeah. And twenty and twenty minutes ratio.
46:10
Okay. Thanks. Copy. Yeah. Yeah.
46:12
Is
46:12
there has that got any
46:15
I know you said you are not there's been other
46:17
work before you in this area. But has that
46:20
got more
46:23
performance related information
46:25
that could be taken on further by you
46:27
sell for others?
46:29
Look, it's screwdrivers. I think I think it's something
46:31
for it's it's something for someone to
46:34
take up and maybe maybe, yeah, investigate
46:36
further. We don't abandon it to coordinate
46:39
with those type of outcomes with performance,
46:41
but
46:42
again, if you're a jump at lease,
46:44
if you're a long jumper, triple jumper,
46:46
think for acceleration,
46:48
I think there might be some yeah, there
46:50
might be some potential there to to to
46:52
think both qualities and and use it as as measure
46:54
of it.
46:56
So it's just I process. Didn't
46:58
the assessment expose the strengths of the aim,
47:01
where we're going with it to to build this
47:03
athlete back up
47:04
to then back
47:05
into back into training.
47:08
Yeah.
47:08
Yeah. I mean,
47:11
you know, as soon as they can run,
47:13
do some basic engineering running, we we bring it in.
47:15
even
47:16
if they're only at basic sort of plan metric level,
47:18
we wanna make sure that the house is in order, you know, so
47:20
that they're they're they're quite proficient
47:23
at the plyometric. They can handle a a good amount of
47:25
plyometric volume, single leg,
47:27
multi direction if if we need to
47:29
pivot the field support player. before we try to
47:31
bring in some, you know, phase
47:33
of volume
47:35
running. And because it's return to run
47:37
phase, particularly for car injury, and where where things
47:40
can clear up again, you know, and there's all that risk of
47:42
the of the
47:42
cabinetry because you're dealing even with the most lintry,
47:45
it's primarily tenant issue that's involved and tenant
47:47
issue takes a lot longer to remodel. And
47:49
so there's a long game and you always have to
47:51
it's easy to if you if you're if
47:53
you're just pure to use symptoms
47:55
as a guide, you can be pain free, you can
47:58
be functionally well, but there's
47:59
ongoing
47:59
remarketing going on there in the background that you don't see.
48:02
And that could be up to six months based on and once
48:04
the reason who who who
48:06
retrospectively or who ended did
48:09
MRI follow ups in in in in in lost of injuries.
48:11
So that that's that's that's gone up for several months. So
48:13
if you have quick corners get back playing or performing
48:16
and you've kind of back up a little bit in your rehab thinking you're
48:18
out woods, you know,
48:19
you're still at a you're at very, very high risk of
48:21
reoccurrence.
48:22
So I think
48:24
it's really important that we we expose
48:26
them to good level of reactor strength
48:28
work and
48:29
a level of volume running. So maybe
48:31
tens and sport obviously, but
48:33
this is something
48:34
that's going to be look at volume anyway, but for field sports,
48:36
maybe having exposure to a
48:38
moderate amount of volume at impasse, moderate to
48:40
high intensity
48:42
for a phase before we can be.
48:44
That's what's comfortable returning back
48:46
to the competition.
48:49
How how important is it to be
48:51
super careful post cat
48:53
injury in that introduction
48:55
back to running unlike something like
48:57
a hamstring where you get
48:59
into high speeds to to get into that
49:01
danger zone. Yeah. Car. Yeah. You're
49:03
in it straight away? It's almost
49:05
like the reverse. So, like, obviously, with a hamstring,
49:07
you probably get away with, like, low low intensity,
49:10
moderate intensity running. I mean,
49:12
again, but I didn't get too much out of hamster injury before
49:15
Martin back three years ago, four weeks out.
49:17
And it's a great 2b. So it was a my
49:19
attendance junction and vice and
49:21
the and I was
49:22
quite aggressive with with rehab and because I was
49:24
rehab
49:25
and myself, and I was I was going to take risks.
49:27
And if I didn't make marathon, you know, it was
49:29
not a big no big deal as soon as they could. managed
49:31
to get it resolved, managed to run a PV that that day,
49:33
but I know it was a sprinter. I wouldn't have got
49:35
away with it because I wouldn't have had it I
49:37
wouldn't have just been able to handle it. Maxim
49:39
has been running, but he didn't have to go find a few things
49:41
for marathon. So yeah.
49:43
But for the calf, injury pretty solid. You
49:45
can probably kinda go short along
49:48
with with with your progression, maybe bring them bring in
49:50
some, like, shorts. Not always a sprint,
49:52
but, like, maybe, working eighty to ninety percent
49:54
of their maximum velocity over, you know, fifty,
49:56
sixty meter repeats.
49:59
They can
49:59
probably handle
49:59
that. And while you're trying to build
50:02
capacity concurrently,
50:03
then you can also start to increase the volume
50:07
gradually over a week
50:09
or two.
50:10
the So
50:11
you can kinda go
50:12
short to long with those
50:14
cabinetry scores in home screens, but you have to go sort
50:16
of, you know, gradually slow to fast.
50:19
you know, and making sure I think the order before we bring
50:21
in high speed running. Cool.
50:23
And your PHD in
50:26
Okay. The added of a killers, a
50:28
killers rehab? A killers
50:30
rehab. Yeah. Northern biomechanics. Yeah.
50:33
the So
50:34
I'm sorry comment towards the
50:36
end. Sorry,
50:36
mate. Twin towards the end? Yeah.
50:38
Come
50:39
towards the end. Yeah. So I'm I'm I'm I've I've one study
50:41
to finish off, and I'm breaking my thesis
50:43
at at moment. So
50:44
hoping to have it submitted in the next
50:47
over the winter months and hopefully have it have my
50:49
defense. Before
50:51
the end of the year, So, yeah, it's been
50:53
been a five year journey.
50:55
So, yeah, the the the broad topic
50:57
we need to learn in biomechanics. So
51:00
if we have
51:02
couple of chapters in it, so two
51:05
papers. Well, one paper would be the horizontal
51:07
rebound test that I mentioned. testing reliability
51:09
and looking at the biomechanical features of that, which
51:11
we have paper in in submission at the moment. And
51:13
then another liability paper for CDK via the
51:15
metric test that we're trying to finish and
51:18
get ready for submission. And then our main
51:20
study would be RCT and
51:22
unrunner's participants
51:24
who take part sports and above running,
51:26
so not just discerning, it's it's field sports, so any
51:28
sports and above is running,
51:29
them who
51:30
have chronic mid portion, it can have turned it up at least.
51:32
So having symptoms more than three months,
51:34
paying
51:35
in the in the mid portion of the tender
51:37
as opposed to the run the heel insertion.
51:39
them
51:40
So we we give
51:42
them we we we randomize them into into one or two
51:44
groups. So one program one group
51:46
follows program that we put together that's
51:48
based on two or three
51:50
high
51:50
intensity sessions a week and multi
51:52
factorials are working on cast strength and
51:54
play metrics and guiding
51:57
the running and then another group follows
51:59
program that's
51:59
kind of by
52:02
it's a silver naga protocol. So
52:04
current silver naga is a prominent researcher
52:07
based in University of Delaware. And
52:09
per
52:09
protocol,
52:11
it's kind
52:12
of similar nature. And that it's it's it it
52:14
it has multi exercise types of, you know,
52:17
combined concentric, e centric, and so on, bring
52:19
it in planck. But probably a little bit less specific
52:21
in terms of how you progress So it's kind of – it's more
52:23
kind of based on symptoms, whereas we're kind
52:25
of hit certain strength targets
52:27
to collect progression.
52:29
to a maximum level
52:31
of tolerable pain as opposed to just relying on
52:33
pain to progress. And
52:34
we test them at start and then at
52:36
week six and week twelve and then we do long term question
52:39
or follow ups. So we look at the running mechanics
52:41
and using three d motion capture,
52:43
and we test our cap strength, hypothetically,
52:45
straight leg and bentley, and
52:47
then we look at their vertical drop jump and single car
52:49
rental rebound.
52:50
So that's been a big study. And they've also got
52:52
single case report that I'm preparing to just submit
52:55
on a football player
52:57
in Ireland who sustained indicators rupture.
52:59
And
53:00
last spring time when
53:03
intercounty training resumed
53:05
after after the restrictions, so the first week
53:07
back and hit a surgical repair. So we're able
53:10
to collect some data on him over the nine
53:12
months is my nine month rehabilitation journey and also
53:14
mapped out his rehabilitation. So, yeah,
53:18
there's four papers in that study. Everything that
53:20
nothing data in my thesis, and hopefully,
53:23
will be useful.
53:26
One last question.
53:29
Biggest mistakes either
53:31
you have made or others make
53:35
when we have been and
53:37
Achilles.
53:39
Cool. Yeah.
53:42
I'll
53:44
put you on the spot there. Sorry, mate. You have. Yeah.
53:46
I've not done that. We all make mistakes. I've
53:48
missed you.
53:54
Yeah. I I think it's actually quite important because, you know,
53:56
so with with attendance, it's it's not just
53:58
the tissue, it's not just the the structural
53:59
damage and
54:01
you
54:02
see in their my scan doesn't always match up to the pain response
54:04
and all that. You know, there's a lot of other factors going on
54:06
that we can't see and it's very hard to
54:08
quantify. Even
54:10
the pain responses to get from a good attendant, a lot of that
54:12
is just chemical noise in in in the attendant. So
54:14
you've got the cells that reacts. You've got
54:16
an inflammatory process. That's not the normal part
54:18
of exercise. We get in the foundry response and normally,
54:20
it resolves itself. And when when
54:23
the sometimes your response kicks off, the the the the the
54:25
sellers in the attendant, the team decides to become active.
54:27
You've got that sort of battle
54:30
between release of roxavendamib, that
54:32
breakdown in tender tissue and then the roxavendamib to
54:34
head to repair us. I know you got your own your
54:36
your inflammatory mediators and then your
54:39
information is resolving
54:41
mediators. And
54:42
oftentimes
54:44
when you have them, when the tenant becomes more
54:46
chronic, you've got extra growth
54:48
of blood vessels. Normally,
54:50
the tenderness that the actual collagen fibers
54:54
don't have much blood supply, direct blood supply
54:56
or nerves of by normally, the northern blood
54:58
supply is on the periphery in in that sort of synovial
55:01
space. But when you've got a chronic
55:03
tendinopathy that you you can actually engross the blood vessels
55:05
towards it that that core of the attendant. And then with
55:07
that, you've got a sprouting of the not the nerve endings.
55:09
And those nerve endings are quite exposed on
55:11
my own edges for their quite exposed
55:13
and noisy area. and it just becomes sensitized
55:16
to those sort of that chemical noise, and that's what kind of drug
55:18
for pain.
55:19
So that's
55:20
a tricky one. And then you've got,
55:22
you know, you've got you know, there's nice
55:24
paper there by, guess, in in
55:26
in Sean London last year. He's part of the current
55:28
seven Eagles Group in Delaware where he categorized
55:31
treated in subgroups of of patients who can
55:33
attend update, those were more structured dominance.
55:35
So it's pretty much like a mismaturing loading
55:37
capacity. And those who were twice
55:40
like a social dominance. So again, there's
55:42
lot of fears and catastrophies and
55:45
beliefs around the early symptoms and thus can
55:48
increase
55:49
towards the sensitivity of the tissue and
55:51
those nerve endings, and then maybe those were more metabolic,
55:53
which probably the less forty people because
55:55
the time it can be sensitive other things go on the body.
55:57
So I think as well as get back to my main point,
55:59
one thing
56:00
that will be learned over the years is to try and
56:02
understand what the patient thinks or the only things that's going
56:05
on, what they're understanding of it is, their processes.
56:07
because now most fear that they're gonna rupture.
56:09
And sometimes, you know, yes, when
56:11
you're rupture, there there probably is some
56:13
pathology there that you might see that
56:16
might be make them a little bit more vulnerable.
56:19
But when you are sore, you're probably not gonna do things that
56:21
are gonna cause you to actually, doing fast and explosive.
56:23
So that pain can be a little bit protective. So trying to
56:25
break down that barrier.
56:28
But, yeah, just definitely trying to involve the patient a lot
56:30
more, and as well as That's one thing I probably
56:32
learned over the years, try to understand what way they're thinking.
56:34
And if it's a rational try in
56:36
a very careful and centered way, try to break that
56:38
down and work through
56:40
it.
56:42
Lavette. Sorry
56:44
to put it on the spot there, but dealt with like
56:46
a dream professional. No, no.
56:50
But not. Thank you for coming on card. If
56:52
anyone wants to keep it to date what you got going on,
56:55
PHD wise, other stuff
56:57
going on, running, etcetera. Where's the best place
56:59
Twitter, Instagram?
57:01
Both. Yeah. I suppose you use Twitter a lot more
57:03
for professional stuff and just find
57:06
a good resource. So, yeah, a lot
57:08
of a good
57:09
resources there. Not actually like to like to try
57:11
and that's what share it is and, you know, it's it's it's a
57:13
good two and two and you're limited with with with characters
57:15
in space to try and get you on pause together precisely. And
57:18
try
57:18
to use it for that purpose and share and
57:20
and as well as learn to motors and
57:21
try and steer the things that don't need to get involved
57:24
in. So in Twitter, yeah, my handler is a common
57:26
person like, like, good in there, good in there, even though it was get
57:28
my own needs and that's other
57:31
characters to it. With the blood check as well?
57:34
Yeah. Yeah. That was Manavonics was here. Yeah.
57:36
We all got out of the bonus back in in none in twenty
57:38
twelve. Did you
57:39
mention I forgot it. So was
57:41
that just a thing that went if you're in the Olympics,
57:43
you know, will take in two thousand twelve? Yeah. That
57:45
time. Yeah. Yeah. Yeah. Yeah. Nice. Yeah.
57:48
I'll take it. And the
57:51
Twitter or LinkedIn
57:53
as well. I often use that more as
57:55
well as for more for professional stuff. But
57:57
Yeah.
57:57
Look, I mean, if we're spot ways, look, I've
57:59
people have been very generous with their time to me over the
58:02
years and have grown up on them. And if someone comes to me with
58:04
a question, I'm always trying to try to have
58:06
them and if I kinda have them join point them in the right direction.
58:08
So
58:08
yeah. always
58:10
happy to take a few free tours.
58:12
Awesome. Well,
58:13
thank you for the last hour.
