Internal foot power in the standing long jump: comparison of distal foot power and foot power imbalance

The internal foot power and work during the takeoff phase of the standing long jump were calculated using distal foot power and foot power imbalance techniques. The foot power profiles were very similar for the two methods with a period of power absorption followed by a period of power generation right before takeoff. The net work during takeoff was negative for both methods with the distal foot power method resulting in slightly more net energy absorption.
