Then Vince Anderson needs glasses or all the overpushing happened in the other half of the accels!
I’ve been coaching for 33 years and have seen it every year since I started.
One of the bullet points there says that the fastest sprint coincided with the fewest steps and the slowest with the most (for the same individual). This is almost always true, if you count enough steps, because the secret is the gradual increase in the stride length throughout. Too long in the first few steps leads to shortening in later steps due to stalling out early.
“Some athletes need to push every step of the 100m”?? Oh please!!
