The aim of this study was to examine the chronic effects of single and repeated jumps training on vertical landing force (VGRF) and jump height in untrained men. The VGRF and jump height were compared after a six-week plyometric training programme containing single and repeated jumps, together with two additional parameters: landing time (LT) and range of the knee flexion during landing (KF). Thirty-six untrained physical education students with a plyometric training background were randomly assigned to a single jump group (SJG, n =12), repeated jumps group (RJG, n =12), and control group (CON, n =12). The SJG performed only single jumps, the RJG executed repeated (consecutive) jumps, whereas the CON did not perform any exercises at all. A countermovement jump (CMJ), repeated countermovement jumps (RCMJ), and a drop jump (DJ) were tested before and after the training. Only the RJG showed a significantly reduced VGRF (p < 0.05) in all tests. Both plyometric groups significantly improved (p < 0.05) their jump height in all tests. The LT was significantly greater in the RJG, compared to the SJG, in all tests. The KF was also significantly (p < 0.05) greater in the RJG than in the SJG for CMJ and RCMJ. The results suggest that repeated jumps are beneficial for simultaneous landing force reduction and jumping performance enhancement.
本研究旨在探讨单次和重复跳跃训练对未经训练男性垂直跳跃力（VGRF）和跳跃高度的慢性影响。在包含单次和重复跳跃的为期六周的增强式训练计划后，比较了 VGRF 和跳跃高度，同时比较了两个附加参数：着陆时间（LT）和着陆时膝关节屈曲范围（KF）。36 名具有增强式训练背景的未经训练的体育教育学生被随机分配到单次跳跃组（SJG，n = 12）、重复跳跃组（RJG，n = 12）和对照组（CON，n = 12）。SJG 仅进行单次跳跃，RJG 执行重复（连续）跳跃，而 CON 根本不进行任何运动。在训练前后测试了纵跳（CMJ）、重复纵跳（RCMJ）和跳下跳（DJ）。只有 RJG 在所有测试中 VGRF 显著降低（p < 0.05）。两个增强式训练组在所有测试中跳跃高度均显著提高（p < 0.05）。与 SJG 相比，RJG 在所有测试中的 LT 均显著增加。与 SJG 相比，RJG 在 CMJ 和 RCMJ 中 KF 也显著增加（p < 0.05）。结果表明，重复跳跃有利于同时降低着陆力和提高跳跃性能。
