The purpose of this study was to explore the effects of an 8-week drop jump (DJ) training program at varying heights on lower limb strength, anaerobic power, and change of direction (CoD) abilities in elite female Chinese wrestlers.
The drop jump (DJ) training program was conducted at varying heights of 20, 40, 60, and 80 cm. The study involved 40 elite female wrestlers who were divided into five groups respectively: Control, DJ20, DJ40, DJ60, and DJ80. Participants engaged in an 8-week structured training program that incorporated drop jumps at the assigned heights for each group.
The results demonstrated significant enhancements in explosive strength and anaerobic power, particularly with DJ40 to DJ60 (d = -2.48 to -5.54), and in CoD performance across all DJ groups (d = 1.07 to 5.25), showcasing a dose-response effect.
Optimal training effects for lower limb strength and power were found at drop jump heights of 40-60 cm, while heights of 60-80 cm yielded the most significant improvements in CoD performance. This highlights the specificity of DJ training heights in enhancing athletic performance among elite female wrestlers.
本研究旨在探讨为期8周、在不同高度进行的跳深（DJ）训练计划对中国优秀女子摔跤运动员下肢力量、无氧功率和变向（CoD）能力的影响。
跳深（DJ）训练计划在20厘米、40厘米、60厘米和80厘米的不同高度进行。该研究纳入了40名优秀女子摔跤运动员，她们被分别分为五组：对照组、DJ20组、DJ40组、DJ60组和DJ80组。参与者参与了为期8周的结构化训练计划，其中包括在每个组指定的高度进行跳深训练。
结果表明，爆发力和无氧功率有显著提高，特别是在DJ40至DJ60组（d = -2.48至-5.54），并且所有DJ组的CoD表现均有提高（d = 1.07至5.25），呈现出剂量反应效应。
在40 - 60厘米的跳深高度发现了对下肢力量和功率的最佳训练效果，而60 - 80厘米的高度在CoD表现方面产生了最显著的改善。这突出了跳深训练高度在提高优秀女子摔跤运动员运动表现方面的特异性。
