We went through this in a great deal of detail in the original forum. There is a big difference between what is athlete input and perception and what is actually happening.
Sprinting is a hind-brain activity and all actions while in contact with the ground MUST be automatic.
A misperception here and a conscious effort to push will cause a shift to the fore-brain, slowing the action down with very negative consequences and Vince’s comments can be construed as encouraging this.
I have had considerable experience working with NFL players on speed issues, including testing them over 40y after technical corrections, and have seen big improvements based on my input, so I don’t accept that there is any difference between what works on the gridiron and on the track.
