Abstract
INTRODUCTION: Velocity-based training (VBT) is an alternative and more individualized approach for determining resistance than percentage-based training (PBT) within a strength training program. However, VBT benefits in female collegiate athletes are not well-documented. The purpose of this study is to compare the effects of VBT to PBT on strength and power in female collegiate athletes. METHODS: Sixteen female collegiate soccer and volleyball athletes were randomly assigned to an 8-week strength and power-focused PBT or VBT protocol. Before and after the training period, vertical jump (VJ), maximal back squat, and reactive strength index (RSI) were measured. A 2x2 factorial ANOVA (α=.05) was used to assess group and time differences in the variables of interest. RESULTS: There was a significant interaction for RSI (VBT: -16.3±4.4; PBT:2.9±24.5; p=0.33), but no significant main effects (p>.05). There was a significant main effect of time for VJ (VBT:16±.0.6; PBT:1.5±0.7) and squat (VBT:11.9±7.7; PBT:11.5±5.6; p.05). CONCLUSION: Both VBT and PBT effectively improved VJ and squat. As such, both methods can effectively improve strength, but VBT may limit speed-based development in measures such as RSI.
