The purpose of the present study was to examine the effects of 6 weeks of 40-, 60-, or 80-cm drop jump (DJ) training on lower limb explosive and change of direction (CoD) performance in collegiate Sanda athletes. Repeated-measure ANOVA revealed that there was a significant group × time interaction for standing long jump test (p = 0.006), counter movement jump test (p = 0.026), Illinois agility test (p = 0.003), square test (p = 0.018), Nebraska test (p = 0.027), t test (p = 0.032), and hexagon test (p = 0.012) due to the best performance observed at post-test compared with pre-test for DJ60 (effect size = 0.89-2.89), and the improvement was higher than that of the other groups. These findings suggest that 6 weeks of DJ training could improve the lower limb explosive and CoD performance in collegiate Sanda athletes and that 60 cm may be the optimal drop height.
本研究的目的是考察6周的40厘米、60厘米或80厘米垂直纵跳（DJ）训练对高校散打运动员下肢爆发力和变向（CoD）能力的影响。重复测量方差分析显示，立定跳远测试（p = 0.006）、反向纵跳测试（p = 0.026）、伊利诺伊敏捷性测试（p = 0.003）、方块测试（p = 0.018）、内布拉斯加测试（p = 0.027）、t测试（p = 0.032）和六边形测试（p = 0.012）存在显著的组×时间交互作用，这是因为与预测试相比，DJ60组在测试后的表现最佳（效应量=0.89 - 2.89），且其提高幅度高于其他组。这些结果表明，6周的DJ训练可以提高高校散打运动员的下肢爆发力和CoD能力，并且60厘米可能是最佳的下落高度。
