The primary purpose of this study was to evaluate whether frontal plane (FP) plyometrics, which are defined as plyometrics dominated with a lateral component, would produce similar increases in vertical jump height (VJH) compared to sagittal plane (SP) Plyometrics. Thirty-two junior varsity and varsity high-school basketball players participated in 6 weeks of plyometric training. Players participated in either FP or SP plyometrics for the entire study. Vertical jump height was measured on 3 occasions: preintervention (baseline), at week 3 of preparatory training, and at week 6 of training. Descriptive statistics were calculated for VJH. A 2-way analysis of variance (ANOVA) with repeated measures was used to test the difference in mean vertical jump scores using FP and SP training modalities. Results showed a significant effect over time for vertical jump (p < 0.001). Moreover, a significant time by protocol interaction was noted (p < 0.032). A 1-way ANOVA demonstrated that only the SP group demonstrated improvements over time, in VJH, p < 0.05. The FP group did not improve statistically. The data from this study suggest that FP plyometric training did not have a significant effect on VJH and significant improvement in VJH was seen in subjects participating in SP plyometrics thus reinforcing the specificity principle of training. However, coaches should implement both types of plyometrics because both training modalities can improve power and quickness among basketball players.
本研究的主要目的是评估与矢状面（SP）增强式训练相比，以横向成分为主导的前平面（FP）增强式训练是否会产生类似的垂直跳跃高度（VJH）增加。32 名初中和高中篮球运动员参加了 6 周的增强式训练。所有研究期间，运动员均接受 FP 或 SP 增强式训练。在 3 个时间点测量垂直跳跃高度：干预前（基线）、预备训练的第 3 周和训练的第 6 周。计算 VJH 的描述性统计数据。使用重复测量的 2 因素方差分析（ANOVA）测试 FP 和 SP 训练模式下平均垂直跳跃得分的差异。结果显示垂直跳跃的时间效应显著（p < 0.001）。此外，还注意到方案间的时间交互作用显著（p < 0.032）。单因素方差分析表明，仅 SP 组的 VJH 随时间改善，p < 0.05。FP 组在统计上没有改善。本研究的数据表明，FP 增强式训练对 VJH 没有显著影响，而参加 SP 增强式训练的受试者的 VJH 显著改善，从而加强了训练的特异性原则。然而，教练应该同时实施这两种增强式训练，因为这两种训练模式都可以提高篮球运动员的力量和敏捷性。
