Is this term used more to define the process of how the swing leg is loaded up as it passes the opposite knee in sprinting? Or the function of CM horizontal/vertical velocity generated from the propulsive effects during the getaway phase?
I assuming both have to do with some positive vertical displacement during toe-off and flight phase. However, is this term meant as a pro-active movement skill or step during certain sprint drills or work sessions? And if so, how might it be performed?
