Volleyball primarily focuses on technical and tactical training with a ball. However, there is growing interest in integrating fitness training into volleyball practice, particularly to enhance explosive strength through plyometric methods, but there is a lack of a direct scientific comparison between training with and without the ball. This study aimed to compare the effects of two training protocols on volleyball players. One protocol combined plyometric exercises with technical gestures (wall drills) using the ball, while the other protocol excluded the ball during plyometric exercises. Twenty male volleyball players (aged 18.6 ± 0.3 years, height 189.8 ± 2.2 cm, weight 79.4 ± 1.6 kg) were divided into experimental (with ball) and control (without ball) groups. The analysis of the results highlights significant improvements in both the squat jumps (SJs) and the countermovement jumps with arm swing (CMJas) for both groups. While there were no significant differences between the groups for SJ, significant differences emerged in CMJas, indicating varied training effects. Specifically, the interaction effect was significant ( = 0.004), demonstrating a meaningful distinction in performance improvements between the two groups. The effect size of the interaction is moderate (η = 0.37, 95% CI: 0; 0.91). These results suggest that incorporating a ball into plyometric training can be beneficial for developing explosive strength in a different way, thereby improving performance due to the motivational stimulus provided. However, given the specificity of the sample and the training protocols used, further studies are needed to confirm these results and evaluate their applicability to a larger sample of volleyball players.
排球主要侧重于有球状态下的技术和战术训练。然而，将体能训练融入排球训练的兴趣日益浓厚，特别是通过增强式训练方法来提高爆发力，但对于有球训练和无球训练之间缺乏直接的科学比较。本研究旨在比较两种训练方案对排球运动员的影响。一种方案是将增强式练习与使用球的技术动作（墙壁训练）相结合，而另一种方案是在增强式练习期间不使用球。20名男性排球运动员（年龄18.6±0.3岁，身高189.8±2.2厘米，体重79.4±1.6千克）被分为实验组（有球）和对照组（无球）。结果分析表明，两组的深蹲跳（SJ）和手臂摆动的反向移动跳（CMJas）均有显著改善。虽然两组在SJ方面没有显著差异，但在CMJas方面出现了显著差异，表明训练效果不同。具体而言，交互作用显著（=0.004），表明两组在成绩提高方面存在有意义的区别。交互作用的效应大小适中（η=0.37，95%CI：0；0.91）。这些结果表明，在增强式训练中加入球可能有助于以不同方式发展爆发力，从而由于提供的激励刺激而提高成绩。然而，鉴于所使用样本和训练方案的特殊性，需要进一步研究来证实这些结果，并评估其对更大样本排球运动员的适用性。
