hey what's up everyone morey croson here and we have a brand new breakdown for you today it's
going to be on kristoff lumieretta the sprinter from france and this is going to be a really great
video because it's going to be the start from the behind view it's taking me a long time to be able
to find a top sprinter that has this view so it's going to be super super informative on helping you
and improving your start as always if you like the information go ahead and click that thumbs
up down below subscribe the channel if you haven't already and if you have any questions or comments
or anything like that you can go ahead and leave those down below we'll hop in the video right now
okay so there's going to be a few really main things that we want to be able to see
here uh while while going through that that behind view which you know is just going to be
very very critical in better understanding from a performance standpoint what we can do in order to
maximize the start so you can see pushing off as always you know we want to think about how we can
get that triple extension you know not everybody is able to get that triple extension but he does
a good job getting those those hips through as well and really getting into that good um angle
within his whole body notice how you can see his head a little bit there you know sometimes guys
will keep those head their head a little bit too low and so you you want to make sure you
can't see your head and then also notice how much extension he's getting in that shoulder how much
of a drive he's getting through that arm and then how he's swinging that opposite arm up and through
gets that foot off the ground a good amount but big thing that really stood out to me
is how fast he's able to exchange his legs and you know how how quick his turnover is so notice
when he's put his foot touching the ground here if we're going to be looking at it from
the frontal planer like that side view his knees are basically even when that foot is touching the
ground and so for it being such a more horizontal movement he's actually getting a good amount of
kind of vertical force here as he's going so you can see that foot's touching the ground
boom and the knees are basically you know that front leg is a little bit in front but
you know not too much so we have a bit of a side bend going on within the spine all kind of normal
stuff that we're seeing a lot of times we see that knee kind of come in the foot kind of go out to
the side that allows you to get a little bit more range of motion as you're going into a hip flexion
or driving that that knee up and through driving that elbow back all the way and this is again
where it is most important to be able to see i want you guys to be able to understand posture
and body control but notice how when he's pushing off with that back leg how he's how much air time
he's getting and how fast he's switching those legs through so when his foot is touching the
ground there again he almost now we're looking at it from this side of the frontal frontal plane he
almost has this knee back to the same height as that that front knee or the same you know
position as that front knee so uh what i see a lot of times is when this foot pushes off right then
right basically right away that front foot touches the ground and that knee is way back behind the
front leg when that front foot's touching the ground right so there's a big difference in
how the force engine being generated if as soon as this foot touches off the ground then this but
touches the ground because that makes it so now your foot contact time ends up being a lot longer
and when we're getting into the the start and how to maximize your start the big thing is how can
we get you to minimize the full contact time as fast we can and the big way to be able to do that
is to be able to get that back knee through back leg through sooner to make it so now when you
land you're going to be in a lot better center of mass a lot better center of gravity and that heel
you know that heel can be higher up that will make it so now when you your foot touches the ground
you'll be able to then transition right back off very quickly so what we see is that when people
land here and the heel is closer to the ground that's going to make it so you have a longer foot
contact time during the start right obviously when you're on the top end speed that's more normal is
you're going to be landing with your your foot you know not obviously in such a high angle here
and you can still maximize that full contact time but when you're starting it's very important
to have that heel really high up you know and he's not over doing it with that foot position
right so he's you know has a low heel angle there it's not like he's getting that that
heel all the way up to his butt he's driving that leg straight through but he's yeah he's
very very quick at being able to transition off because of how quick he's able to exchange
those legs and and be able to get very vertical very quickly so within this third step here
he's already pretty vertical overall in terms of where his his leg is landing right he doesn't have
a very flexed knee right there his knees not super bent he's landing with a pretty straight again
heel up again driving that back knee through so you if we're looking at it from that frontal plane
they're about at the same you know height of that back leg is a little bit back right it's
not exactly even but it's also not way behind like you know we'll see a lot of guys that are
going through their start all right so again you can look at some of the body position stuff you
know that's important as well you don't want to end up being too flexed you don't want to
be too straight up you want to be able to maximize the the extension within the arms
but those are things that that i think a lot of us already know right and if you guys aren't watching
yourself sprinting from behind and getting some some technical advice here then you're really not
going to be able to improve your speed to the same level as being able to get some really technical
precision into your sprinting mechanics so videos like this and getting a greater understanding into
your actual you know mechanics and and really biomechanics is critical in understanding now
what you need to improve on whether it's strength power range of motion posture uh turnover speed
contact time start acceleration top end speed there's so much to to be able to understand that
you know you really got to be able to break down your sprinting so then you can isolate okay these
are the areas to improve because if you just keep on trying to squat more deadlift more or
you know just work on your start or or just work on these different random parts of your sprinting
then you're never ever going to get that that really great result that you're looking for you
got to be able to focus you've got to be able to isolate and that'll be the way to make significant
improvement in the shortest amount of time all right as always guys thanks for watching the
videos if you have any questions or anything like that check out the description we have a
lot of different resources for you guys to be able to improve from a sprint perspective as
always i highly recommend you joining some of our programs here we got a lot more people that
have been joining here in the last few months just because of everything going on with with
covet and really been seeing some great results from this friendly perspective and i'm excited
to share them with you but for now as always thanks for watching and we'll talk to you soon
