Yeah, the fastest sprinters can apply the largest vertical and horizontal forces in the proper direction in less time, and the goal of horizontal force is clear (for every action, there is an opposite and equal reaction):the more horizontal force you apply, the faster you sprint, and one goal of vertical force is that you explained in the video, but there is also another. And it's this:imagine that relative to an straight horizontal line (it's 0°,and vertical line is 90°), your horizontal force is created by applying more force in that 45° angle, and since it's doing an move at that angle, for every 1 meter movement in that direction, there's 0.5 m both vertical and horizontal movement, which means that you need 2 times less force to accelerate and hit a speed the same as vertical speed if the application of force was 90° (just vertically), which means that if the pressure between your foot and ground is less (created by applying more vertical force in that very very early part of the ground contact (maybe first 2 hundreds of second), then your „weight” to the ground (the pressure) is less, and if it's 2 times less (by creating 2 times more vertical force in that early part), then you would need not 2 times less force to accelerate at the same rate in that direction of 45° as in vertical by applying not 2 times less, but 1 unit of force, but 4 times less force to do that (here was an example of 45°, but you can even make it as close as 20° angle). So making your foot-ground pressure less, you make your horizontal force production more efficient and by applying 2 times more vertical force in that early part, your horizontal force units (Newtons) are 2 times more efficient and move you 2 times faster in that direction (and we should also add air resistance, but if the direction of air moving and your moving is same, and his and your top speed are equal, then you would not have air resistance, and that ibly matters, which can be done, but here is also air resistance, and if it is 100 Newtons (caused by high body horizontal acceleration) and your force direction angel is 45°, you should „fight” against 50 Newtons of these, but less angle relative to horizontal line makes you evn

Also, reducing your foot-ground push force reduces your braking forces, and even then you need of less horizontal force to run at the same speed (in two ways:by creating less drag, and by the explanation of the first comment).

Here's question how how ur knowledge is good but how

What do u try to do

Appreciate that bro! After some time to recover from season, it’s back to work 😤😤

So what exercise would be best to train horizontal force?

@@PREZIDENTIAL I guess you mean exercises apart from sprinting. I can't explain it here. But basically i would recommend nothing bilateral. Instead exercises with a strong focus on the core and the contralateral sling. (Exercises where one side hits the extensor cahin and the other the flexors simultaneously). Also exercises with strong emphasis on rate of force relaxation. I think rate of force development is clear and it's very important. But rate of force relaxation is how quickly you can decrease muscle tension (force). And it is probably the most important skill for top speed sprinting.

Thank you man!

Thanks for watching! Yeah I’m really grateful to have year round training. Gets a bit toasty in June/July but it’s better than -20 in the winter like some places have!

It should help, yeah

@@ATHLETE.X given the form and technic remain correct. But extra power and strenght doesnt always necessarily evolve to speed. So it maybe it need some effort.
