As it relates to maximal sprinting - a quick question to the S&C folks:
Is lifting maximal weight the ONLY way to get stronger?
The answer is obvious: of course it's not!
Sprinting is no different.
For others (e.g. those with poor technique), other methods will be more-appropriate
... just not always MAXIMALLY
Sprinting maximally is NOT a necessity to improving speed
Intensity - at least as measured by velocity - should usually be governed by technical proficiency.
Mechanics first - load second
