hey what's up everyone morey croson here and today we're gonna be doing a breakdown on christian
mccaffrey it's been about a year and a half since i did a breakdown on christian mccaffrey so i've
done it in the past but i know i've personally gotten a lot smarter with better understanding you
know how to do these breakdowns and also you know what is some key information to be able to take
from these breakdowns and i think within christian recovery server can really learn a lot of great
information to utilize within our own start in order to really maximize our overall performance
so as always if you like the information go ahead and click the thumbs up down below subscribe the
channel if you haven't already and if you have any questions comments or anything like that
go ahead and leave that in the comments down below we'll hop in the video right now okay so christian
mccaffrey here is you know somebody that just from a technical perspective i think has some great
great mechanics in the 40-yard dash and again some things that i think we could really take away from
you know the first thing i always talk about and i know if you've watched these videos before you
already know but if this is your first time uh watching that front knee and really understanding
you know how that front knee goes is an important thing and seeing how it drops initially like that
there's some guys that talk about how that back foot you know shouldn't go back at all um i do
think that it ends up having to go back and push down all the best guys that do it john
ross you know christian mccaffrey really anybody that that has a great start marquise good win
all go and they push down with that back leg first drop that front knee down get full extension
within the back leg but what we're really looking to see is how much time is being spent on the
ground so we can see here um or what happens here is he first touches the ground here 9.03
and he's off the ground at about 920 maybe 921 we'll say so that's about a 0.18 for contact time
and that really ends up being a pretty average contact time within that that front leg and this
is something that is fairly easy to be able to do yourself here and being able to understand
you know how to um break down your own sprint and your own start to be able to see what are some of
the necessary adjustments that need to be made and the reason i'm doing this is just because i
recently did a breakdown and it kind of exposed some of the things that you know needed to be
corrected within a start there and so what ends up happening here is when you can really go into the
numbers so now we'll go to the second step 9.43 and he pushes off at 960. so again that's 0.17
so when you really go and get to looking at the numbers you can see how you're progressing
over the point over the course of the sprint and how well you're able to transition from
your kind of start phase into your transition phase or drive phase and into your top end speed
phase so you got 9.18 and then one seven notice how high his his legs already are this is going
to be his third step touching the ground here he's going to touch it about what is that let's say 969
and is off by probably 981-ish right so he's already within those first three steps getting
close to or are already um in into you know point one two around time period maybe point one three
in terms of how much time that you spend on the ground usually what i say is that within four
steps you want to be spending nine nine three under point one four seconds on the ground
and off at 1003 right and so that is already at about point one so he has tremendous acceleration
right and one of the big things that i think has an impact on that because in four steps to already
have a full contact time of 0.1 um is great you're going to be setting yourself up to run
something like a you know four four four five by doing that which is where christian mccaffrey was
at and so what what's happening is that if we look back you can see how he's driving that knee up and
getting getting a lot of height within the leg right and then able to create a lot of pullback
right so from getting this knee all the way up to the position it is and then being able to
pull that foot back down and land in a position where his foot you know not directly underneath
the hips but pretty close underneath the hips makes it so now he has the power generated before
his foot touches the ground that makes us so now when he's put touching the ground
he can really be quick with that timing right so what ends up happening to guys is that they don't
get the foot out in front very well and because that when the foot's touching the ground it's
a lot more of a force deriving action right which means that you have to utilize that force spent or
that time spent on the ground in order to generate the force you need to be able to propel yourself
off and generate the necessary yeah force or torque needed to be able to get a great leg cycle
what christian mccaffrey does that's different is he's getting that foot all the way out in
front pulling that leg back before his foot even touches the ground so now when the foot touching
the ground it's a it's just absorbing and then pushing right back off so it's a lot more of
like a plyometric effect where you're just going to be bouncing it's like a rebound where it's just
going to go the force is going to go into the ground and then take it right back out and push
right off so now he doesn't have to utilize that that time spin on the ground as much to be able
to generate his force he already has the force generated within his body which makes it so he's
able to get under that 0.14 and under that that first four steps which i think is a critical part
of being able to run a elite time when it comes to running a 40 yard dash obviously you know you want
to be able to get in like the 0.12 area within those first four steps and that's how you're
going to be able to run you know closer to the low four fours or into the four threes and that's a
very very important part of being able to you know sprint fast and notice you know because everybody
tries to say stay down you need to stay you know in that in that drive phase for a long time and
you do need to stay in the dry face it's not like i'm saying you know that's not an important
part of the run but notice how fast he's able to get himself from this kind of starting position
into you know the spine basically being upright right i mean he doesn't spend
a lot of time with his chest down eyes down heads down you know nothing's really looking down
and this is his already seventh step right here you know he's basically looking straight up he's
so he's able to transition from his start face through his transition or drive phase to his top
end speed really quickly or at least the top end speed positioning right it's not necessarily he's
in his top end speed and so it's still considered the drive phase because he's still creating that
force but he's in the top end postural position right so you don't want to end up staying down
for too long because you know that makes it so you end up staying in your drive phase longer than you
necessarily need to you want to be able to get your hips through work on that hip extension and
really make sure that you're getting that that leg drive and creating a lot of force down into the
ground and that will make it so then you can get into your top end speed a little bit faster this
is really important when it comes to the 40 and now once you get to your top end speed you got to
just be able to hold it for a long period of time when it comes to being able to run the hundred or
something like that now you know once you get into more of like a 200 meter race you don't need to be
as quick to get to your top end speed you have to because you have the turn that you have to
be able to get through so you have more time to be able to develop and then you get to that last
straight away and now you want to be going to your top end speed but when it comes to
running the 40 running the 100 you're running in a straight line the whole time it's about
being able to get your top end speed fast and then being able to maintain that and just understanding
the mechanics to be able to do that so you know within by doing this breakdown hopefully you get
a better understanding of where your start should be if you know you have any questions about that
would be happy to help you out i will say you know getting these breakdowns done will give you
a clear understanding of what needs to be worked on within your 40. we currently have a program
available right now within the program you get a free breakdown right it's a three-month program
only 109 i highly recommend it if you guys are looking to get faster than the 40 and a very very
quick amount of time just because we'll be able to identify what you need to do in order to improve
within your mechanics and then be able to get you on a plan to be able to address that and improve
that so you know i highly recommend you doing that especially if you've been watching these videos
and kind of understand what i'm talking about here or into the analytics of it all everybody that's
in the programs now really enjoy the analytics and i hear that a lot and it's something that i'm glad
people out there really enjoy it because i think it can really help them in improving their speed
all right as always thanks for watching these videos and we'll talk to you soon
