Stronger Finish

good point by herb.carl lewis could change automatically under the supervision of TT whom he had utmost trust in.also the breakdown of the 100m which TT believed in was to accelerate smoothly to 60m,maintain and relax to the finish this is exactly waht we see when we watch videos of carl,leroy(in 94 onwards),mark witherspoon and mike marsh.all these guys had great acceleration and strong finishes just because they are training and thought how to accelerate smoothly

I have read something about foot contact time in sprinting and another about weight training. I came out with a conclusion that I’d wish I’d get any verification on.

When someone reaches top speed his foot touches the ground for about 0.08-0.10. Ok. Now a person would need much more than that for maximum force production to the ground. We’re talking about 0.4 give or take depending on the person. So If my max force that I can generate if I’ve given all the time I need was about, lets say 100 Newtons for example. Then at about 0.1 time I can only generate, lets say 50 Newtons. OK. When I train in the gym I’m usually not working much on moving the curve to the left. In fact I only work on extending the curve. That is improving maximum strength ( given the time needed to produce it ). So now my max is about 200 Newtons. But still foot contact give only 50 Newtons.

Some people say that this means weight training is usless since I don’t use that extra strength during my foot contact. But then I say that when max was 100 N each foot contact was working at about 50% of maximum. But then after weight training. You are only working at 25% of maximum… Doesn’t that mean that if I’m stronger. I can maintain my top speed longer cause its not , lets say - taking much out of me -?? Its really interesting to know that.

while doing plyometrics would shift the curve to the left. Which would mean that I can produce more force at that specific 0.1 time of foot contact. I guess I combination of plyometrics and weight training would be great. ( if sprinting was there to apply of course ) I just wanted to verify these thoughts.

Being stronger should make things feel easy, which should help you to relax, which should help max velocity.
Sprinting is more to the left than any type of plyo.
