This study compared the effects of Flywheel Resistance Squat Training (FRST) vs. Traditional Resistance Squat Training (TRST) on lower body strength in female collegiate basketball players.
Nineteen participants were randomly assigned to either the FRST group (n = 9) or the TRST group (n = 10) through a random number draw. Both groups underwent a 6-week intervention with training sessions conducted twice a week. The FRST group utilized an inertia of 0.075 kg ·m, while another group trained at 80% of their one-repetition maximum (1RM). Each training session consisted of 4 sets of 8 repetitions with a 3-minute rest between sets. Both groups performed standardized warm-ups and stretches before and after each training session. The effectiveness of the training methods was assessed through the Countermovement Jump (CMJ), Reactive Strength Index (RSI), Eccentric Utilization Ratio, Running Vertical Jump, and 1RM squat.
The FRST and TRST groups showed differences within groups in both CMJ and 1RM squat ( < 0.01), with the FRST group demonstrating moderate effect sizes in CMJ (Hedges' g = 0.59) and 1RM (Hedges' g = 1.01). However, there were no differences between groups ( > 0.05). The Eccentric Utilization Ratio showed a small effect size ( = 0.78; ). Additionally, Reactive Strength Index and Running Vertical Jump exhibited low test-retest reliability.
The two groups did not exhibit a statistically significant difference. Nonetheless, both FRST and TRST demonstrated positive effects on 1RM squat and CMJ performance compared to baseline values for each method. Therefore, flywheel resistance training can be considered an effective alternative to traditional resistance training for enhancing strength levels in female basketball players.
本研究比较了飞轮阻力深蹲训练（FRST）与传统阻力深蹲训练（TRST）对女子大学篮球运动员下肢力量的影响。
通过随机抽签将19名参与者随机分为FRST组（n = 9）或TRST组（n = 10）。两组均接受为期6周的干预，每周进行两次训练。FRST组使用0.075 kg·m的惯性，而另一组以其一次重复最大值（1RM）的80%进行训练。每次训练包括4组，每组8次重复，组间休息3分钟。两组在每次训练前后均进行标准化的热身和拉伸。通过反向纵跳（CMJ）、反应力量指数（RSI）、离心利用率、跑步垂直跳和1RM深蹲来评估训练方法的有效性。
FRST组和TRST组在CMJ和1RM深蹲方面均显示出组内差异（<0.01），FRST组在CMJ（Hedges' g = 0.59）和1RM（Hedges' g = 1.01）方面表现出中等效应量。然而，两组之间没有差异（>0.05）。离心利用率显示出较小的效应量（= 0.78；）。此外，反应力量指数和跑步垂直跳的重测信度较低。
两组之间没有统计学上的显著差异。尽管如此，与每种方法的基线值相比，FRST和TRST对1RM深蹲和CMJ表现均显示出积极影响。因此，飞轮阻力训练可被视为增强女子篮球运动员力量水平的传统阻力训练的有效替代方法。
