The aim of the study was to verify the impact of the jump height measured during the serve, attack and block on their effectiveness. The analysis of the literature and observations lead to the hypothesis that despite the similarities in men's and women's volleyball, the nature of the way of playing between women and men differs. The observation covered 39 male and 24 female elite volleyball players. We used a proprietary software tool, namely OpenCV to assess the jump height library. The analysis was performed on the jump serve height (SJH), attack jump height (AJH), and block jump height (BJH). The following analysis was performed to confirm the differences in the height of the jump and partially confirm the hypothesis. The main difference between men's and women's volleyball is how the serve, attack and block jump height affect winning or losing match sets. In male volleyball players, there is a decrease in the parameters of SJH, AJH and BJH in subsequent sets of matches, while in female volleyball players this relationship is reversed. For men, it seems reasonable to strive to increase the height of a jump to maximize effective offensive actions, as well as to maintain the developed performance throughout a match. In women's volleyball, it is worth using such training measures that allow players would achieve their maximum jumping abilities from the first set, and the main training goal should be focused on the technique and tactics of the whole team.
本研究旨在验证发球、扣球和拦网时所测跳跃高度对其效果的影响。文献分析和观察结果提出假设，尽管男子和女子排球有相似之处，但女子和男子的打球方式本质上有所不同。观察覆盖了 39 名男性和 24 名女性精英排球运动员。我们使用了一种专有软件工具，即 OpenCV，来评估跳跃高度库。分析了跳跃发球高度（SJH）、扣球跳跃高度（AJH）和拦网跳跃高度（BJH）。进行了以下分析以确认跳跃高度的差异，并部分证实了该假设。男子和女子排球的主要区别在于发球、扣球和拦网跳跃高度如何影响赢得或输掉比赛。在男排运动员中，随着比赛后续轮次的进行，SJH、AJH 和 BJH 的参数呈下降趋势，而在女排运动员中则相反。对于男性来说，努力增加跳跃高度以最大限度地提高有效进攻动作，以及在整个比赛中保持已发展的表现似乎是合理的。在女子排球中，值得采用允许运动员从第一局就发挥出最大跳跃能力的训练措施，而主要的训练目标应该集中在整个团队的技术和战术上。
