Abstract

Background: It has been suggested that velocity-based training (VBT) improves real-life performance in sports, such as jumping, but studies rarely examined the associations between variables derived during VBT (VBT-variables) and jumping performances. Objective: The aim of this study was to investigate the associations between VBT-variables derived during deadlift exercise executed at different loads and anthropometric variables, and vertical and horizontal jump performance in young athletes. Methods: Seventeen youth soccer players (16-18 years old) were included. Predictors were body height, body mass, body fat percentage, and VBT-variables (force, power, and velocity) measured at different loads (45%, 55%, 65%, 75%, 85%, and 95%) of a one-repetition maximum deadlift (1RM). Criteria included tests of vertical and horizontal jumping performance. Results: The VBT-variables are more strongly correlated with horizontal jumps (Pearson's r up to .81) than vertical jumps (Pearson's r up to .75). The VBT-variables for the deadlift recorded at lower loads stronger correlated with jumping performance than the VBT-variables recorded at higher loads. Conclusions: Results of the study suggest that light-to-moderate loads (45%-65% of 1RM) maximize power output and are therefore more strongly related to jumping performance in youth athletes. Further intervention studies aimed at the improvement of jumping performances using the VBT are warranted.

青少年足球运动员基于速度的训练装置中得出的变量与跳跃表现之间的相关性分析：多元回归研究

背景：有人认为，基于速度的训练（VBT）可以提高现实生活中的运动表现，如跳跃，但研究很少检查VBT过程中得出的变量（VBT变量）与跳跃表现之间的关系。目的：本研究的目的是调查年轻运动员在不同负荷下进行提举练习时得出的VBT变量和人体测量变量与垂直和水平跳跃成绩之间的关系。方法：选取17名16～18岁的青少年足球运动员。预测因素是在一次重复最大升力（1RM）的不同载荷（45%、55%、65%、75%、85%和95%）下测量的身高、体重、体脂百分比和VBT变量（力、功率和速度）。标准包括垂直和水平跳跃性能测试。结果：与垂直跳跃（Pearson’s r高达.75）相比，VBT变量与水平跳跃的相关性更强（Pearson's r高达.81）。与较高负荷下记录的VBT变量相比，在较低负荷下记录到的提举的VBT变项与跳跃性能的相关性更强。结论：研究结果表明，轻至中等负荷（1RM的45%-65%）最大限度地提高了功率输出，因此与青年运动员的跳跃表现密切相关。有必要进行进一步的干预研究，以提高使用VBT的跳跃性能。
