40 yard dash

The training effect of the flying sprints can be two fold:
1: The increased capacity for 40y by increased high speed distance tolerance (single and multiple), stretching the energy envelope just to the right of the event itself.
2: The increased capacity for 40y by increased speed, stretching the EE just to the left of the event itself.
While both can play a role, 2 will be far more important, especially for the big guys, because:
A: top speed occurs well within the 40y run itself, directly affecting the time, while backs may achieve top speed beyond the 40y mark therefor affecting performance indirectly.
B: Power will always predominate over SE with both groups but especially with the big guys.
So often the big guys are subjected to gassers which I find counter-productive.

Agree on all points.

While I’m as opposed to gassers as you are, the thought of them being eradicated from the training of American footballers might come around the same time as the death of the sun.
