Participants were required to land on a force platform after spiking a volleyball from a four-step approach before and after an intervention involving visual and aural augmented feedback on correct jumping and landing technique.
Main Outcome Measures:
Mediolateral (ML), anterioposterior (AP), and vertical (V) GRF normalized to body weight (BW).
Augmented feedback was found to significantly (P = 0.01) decrease VGRF by 23.6% but not ML (25%, P = 0.16) and AP (4.9%, P = 0.40) peak GRF.
A single session of augmented feedback may be effective in reducing VGRF in collegiate athletes.
