Have you considered that second guessing your coach on an internet forum is about the single most disrespectful thing you could possibly do as an athlete? Either he is your coach or he isn’t.
If he is, listen to him. If he’s not, don’t waste his time or insult him like this.
As an athlete I look to progress my times with the absolute best path of methods. I have 2 different coaches (school/club) and second guess a lot of methods.
I could do the front splits, but coming from a hammer back ground my body had been built to do that, from a flexibility point of view was more flexible then most sprinters yet my sprinting stride sucked.
My point is to keep working on the sprint stride and should improve, oh that and trust the coach.
Place tape markers at every meter (preferably in the middle of the lane where you place your feet) and film from the side. You should then be able to estimate your stride length very well. Also, be sure to achieve full speed!
Of course horizontal velocity is a factor. That’s given. But vertical diplacement is a much more adjustable factor and the factor that separates the shuffler from the long strider.
You took you’re hips out from the begining. At first you were set up in a good position and then lifted you’re butt up before the lift. Keep the butt down and do the lift.
All the videos are old and the sprint videos have about half a second of film worth analyzing.
You’re young. Just keep training and stop worrying about the minutia and asking stupid questions–it will only hinder your progress. Get out of the mindset now that strength in the weightroom equals or even approximates strength on the track and that strength in the weightroom is going to translate to improvements on the track without significant work. Looking at your sprint videos alone it looks like you are stuck in this syndrome already because your upper body is incredibly rigid and it is hard to say, but your hips actually do look fairly tight in that video. ROM on mobility drills or stretches =/= muscle tone and tissue quality. This is why there are plenty of girls that can do all of the splits in the world and still look like their pelvis is in rigor mortis when they sprint.
yah i know what you guys are saying, couple guys told me that when i originally showed the videos on another forum and i’ve mostly fixed the technical issue in my deadlifts now.
Can you clarify further into this?
what do you mean my upper body’s rigid? and if mobility stuff/stretching aint gonna be good for me, whats your reccomendation?
