hey what's up everyone morey croson here and we have a great topic for you today we're going to be
talking about everything that has to do with the shin angle and where to start the video right now
this is the newest edition of the performance side reach your individual goals you don't want
to talk about straight lines we also want to talk about your delivery quick we break
down your video let's make you into the quarterback i know you can become
alright so the shin angle is something that's really important when it comes to really
acceleration for sprinters in particular but anybody who's trying to run fast you have to have
a really great understanding about you know shin angle and i think the more educated you are about
you know how to run faster it gives you the opportunity to be able to really be
focusing in your practice and that ends up being such an important thing guys especially for
anybody that is again sprinter looking to run fast is like when you're actually going and
working on you know running faster you have to be very focused on what it is that you're doing
every step matters every part of each step matters and so you really want to be in tune
with your body to understand what's going on to then therefore know how to improve and so
what we're going to be talking about with the shin angle and there's really two main things right we
have a positive [ __ ] angle which is going to be anything less than 45 degrees which is really what
we're talking about here so if we go and create a little do this real quick so with the shin angle
we're looking at here is the angle of the shin in comparison to the track i'm trying the best that i
can here to make it so it's something that makes sense but really a positive shin angle is when
this angle is below 90 degrees right so anything whoops anything below 90 degrees ends up making
it so this is a positive shin angle so um here we could see exactly where we were at there uh
with that with that shin angle so you really want it to be in around that 45 degree angle i really
like to be able to make it so we can get as close to kind of that that perpendicular with the track
look going on here just to really be able to make it so it's closer to you know a lot of times the
top track athletes are going to be in that like 45 degree angle right and this is coming out of
the blocks obviously so somewhere around there this is saying it's like closer to 40 percent
or 40 degrees we're going to look at here we'll go and do the same thing so yeah this is about
30 degrees this is both christian coleman and and both of these and so we got really closer to
30 degrees according to this here and then we got about 45 degrees or sorry 39 degrees on the right
and this is something that is really great with christian coleman he has such a great ability to
create an amazing shin angle especially during that acceleration what happens
is like as you're first starting you have to be really great and really that second step is
super important and being able to achieve that chin angle right and understanding how to really
maximize your acceleration phase and so you can see it's a little bit bigger there 42 degrees but
point being is understanding exactly what that that angle is so it has to do with the track there
and where your shin is in comparison to you know the track so you know he's at about a 42 degree
angle again this is you know not perfect science in terms of how we're doing it but it gives us a
good idea of around where he's at uh again it goes up to 90 degrees right and so anything that is in
that 90 degree area is considered a positive shin angle now the cl the lower we can get it in the
acceleration phase is better the the start phase the acceleration phase is better off we're going
to be and then as we get to our top end speed what happens is we get to more of what's called
a negative shin angle which is going to be with a 90 degrees right so like basically straight up
or higher right so anything above 90 degrees is gonna be in that positive shin angle category so
if we look to see christian coleman here this is when he was running that that 40 yard dash
so you can see when he gets to that top speed he's more in that like straight down his shin
angle is basically going straight down or is basically exactly perpendicular with
the ground and so that ends up being the big difference between what you know first what is
the shin angle right so the shin angle has to do with the track and your shin the second thing is
what is the difference between a positive shin angle and a negative shin angle so positive shin
angle is when your the the angle of the shin in comparison the track is anything below 90 degrees
and then a negative shin angle is going to be 90 degrees or greater and so and really when we're
talking about a negative shin angle we want to have that more at top end speed when it comes to
a position angle we want to really have that at our acceleration phase and in terms of how much
it should be changing you know we could probably you know if you could start off with closer to
you know a about 40 degree shin angle would be a goal right 40 to 45 would be a huge goal
especially for guys that are like five ten uh to like six two right anywhere in there
you could do the better your shooting angle could be or the lower the closer to 40 the [ __ ] angle
could be the better you are and then from there about a three degree increase on each step okay
um so if you're going to take a side view here as you're going through so you can see that was
we said it was about 39 there right when he was landing boom okay and then here it got up to like
42 ish right so you want to end up building some degree of increase as you're going through but
you don't want to necessarily go from you know 40 degrees to 75 degrees right away and i think a lot
of people end up having that issue where they go from like a first step having a great shin angle
great shin position to second and third step really starting to lose that that great shin
position and what's important when we're talking about this is one we have to have great range of
motion within that ankle joint and and foot joint to be able to get that those toes all the way up
but more importantly when the foot lands we have to have a lot of stability within that ankle right
because what ends up helping you and being able to achieve more range of motion within the ankle
is by having more stability within the ankle i think a lot of people make this mistake
where you just think that you just need to be able to stretch and stretch and stretch your
ankle stretch the ankle and while you that is somewhat degree to some degree correct you want
to be able to eccentrically do it right so you want to be actually adding resistance to it so
now when you're actually improving that range of motion you're doing it through a eccentric
contraction of the muscle and that will set you up more so for performance enhancement instead of
you know just having the range of motion because like you know there's a ton of people that do yoga
all the time but they're not running 100 meter sprints and you know the olympics or you know
sub 45 40 yard dashes so the reason is is because they're not working on an eccentric contraction
of the muscle they're just stretching so it's a different type of training when it comes to
performance enhancement or speed enhancement we're talking and thinking about being able to increase
the range to that e-center contraction or through a even concentric contraction of
like your anterior tib like the muscles on the front part of the shin and an eccentric control
of a lot of the muscles on that posterior side as well as a lot of the muscles on
you know the side of the shin right so both of the there's muscles all through here that they
need to be able to be strong they have to be able to control all that force you're putting
down in the ground because chris coleman the reason he's running fast is slow motion
reason he's running fast is because he's creating so much force into the ground that that allows him
to be able to generate all the power and the speed necessary to be able to run as fast as he does
right and so what has to be understood is that in order to do that it creates a ton of stability and
control within the ankle joint so when your foot hits the ground your foot can't hit the ground and
be wobbly right you need to hit the ground and be strong and stable and be able to transition
right back off and that's what allows you to have a great shin angle right is being able to maintain
this position because if you can't maintain this shin angle here what's going to happen is that
you know your first step might be good but then after that you're going to really quickly start to
increase the shin angle simply because your body can't balance it can't control where you're at so
you know if you're struggling with having multiple steps of having a great positive shin angle
it's because of a lack of stability and control within that ankle joint and maybe even within the
core there's a direct correlation within you know how well you can get dorsiflexion within the ankle
with how well you're able to utilize like your transverse abdominis and so um going deeper into
that understanding that is going to be for another video but point being take consideration into how
your shin angle is applying to your ability to reach top speed because that's what it's all
about is how well can you start how well do you go through your drive phase and that will make you
so you set up yourself for your top end speed and so if you don't have a great understanding of how
you can maximize that this video will help you out to be able to see you know where your shin
angle should be at what are some exercises to be able to help you and really how can you apply that
to your your current training to really make it so you can take your your game to the next level
