Context:
Frequency and magnitude of ground reaction forces (GRF) have been implicated in causing injuries such as “jumpers knee.”
Objective:
To investigate whether a single session of augmented feedback concerning landing technique would decrease GRF.
Design:
Pretest posttest experimental design.
Setting:
University biomechanics laboratory.
Participants:
Fifteen female Division 1 intercollegiate volleyball players.
Intervention:
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).
Results:
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.
Conclusions:
A single session of augmented feedback may be effective in reducing VGRF in collegiate athletes.
