  • 摘要:International Journal of Exercise Science 8(2) : 134-144, 2015. The purpose of this study was to compare the effects of an aquatic- (W) and land-based (L) plyometric program on balance, vertical jump height, and isokinetic quadriceps and hamstring strength. Thirty-four participants were randomized into three groups, W (n = 12), L (n = 11), and control (n = 11). The W and L groups completed an eight-week plyometric program. A two-way repeated measures ANOVA revealed a significant main effect of condition (F = 346.95, p < 0.001) and interaction between condition by time (F = 1.88, p = 0.01). Paired samples t-tests revealed statistically significant improvements from pre- to post-testing in the L group for isokinetic quadriceps strength at 60 degrees per second (p = 0.02) and hamstring strength at 120 degrees per second (p = 0.02). Statistically significant improvements were observed from pre- to post-testing in the W group for balance (p = 0.003), vertical jump height (p = 0.008), isokinetic quadriceps strength at 60 and 120 degrees per second (p < 0.001), and hamstring strength at 120 degrees per second (p = 0.03). Results demonstrate that aquatic-based plyometric training can be a valid form of training by producing improvements in balance, force output, and isokinetic strength while concurrently decreasing ground impact forces.
