The athlete’s take-off velocity increased with increasing run-up velocity (solid line). Also shown are the horizontal and vertical components of the take-off velocity (dashed lines). The grey line is the line of equivalence between run-up velocity and take-off velocity.The athlete’s take-off velocity was less than his run-up velocity and the faster the run-up velocity the greater the loss of velocity.
