This really does amaze me, do you honestly believe there is anyone who doesn't get what acceleration means? Really? REALLY?
Dude...
Reaction to the gun/strart.....now what happens, yep.....acccerate....UNTIL...a sprinter reaches his topend/max velocity.....then its sustain/maintain....then decellerate.
Pay attention....
Those able to maintain/sustain a higher % of their MV longer (meaning they dellcerate at a slower pace) are the ones who wins the races. Ok?
World clas sprinters reach MV at around 60/70m, then it's all about speed endurance.....ok? That is why 100/200m sprinters train at 300m, that SPEED ENDURANCE is the most important aspect of a 100/200m sprinters game. Yes, not so in a 40/60. There it's just start/accelerate.
I know....huh?
