Abstract

Objective: 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.

Methods: 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 ·m2, 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.

Results: The FRST and TRST groups showed differences within groups in both CMJ and 1RM squat (p < 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 (p > 0.05). The Eccentric Utilization Ratio showed a small effect size (p = 0.78; η p 2 = 0.01 ). Additionally, Reactive Strength Index and Running Vertical Jump exhibited low test-retest reliability.

Conclusion: 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.

飞轮阻力深蹲训练对女大学生篮球运动员下肢力量的影响。
目的:比较飞轮阻力深蹲训练(FRST)与传统阻力深蹲训练(TRST)对女大学生篮球运动员下肢力量的影响。方法:通过随机抽签将19名参与者随机分配到FRST组(n = 9)和TRST组(n = 10)。两组都进行了为期6周的干预,每周进行两次培训。FRST组使用0.075 kg·m2的惯性,而另一组以其最大单次重复(1RM)的80%进行训练。每次训练包括4组,每组重复8次,每组之间休息3分钟。两组在每次训练前后都进行了标准化的热身和拉伸。通过反动作跳跃(CMJ)、反应强度指数(RSI)、偏心利用率、跑纵跳和1RM深蹲来评估训练方法的有效性。结果:FRST组和TRST组在CMJ和1RM蹲下上均有组内差异(p < 0.01),其中FRST组在CMJ (Hedges' g = 0.59)和1RM (Hedges' g = 1.01)上表现出中等效应量。各组间差异无统计学意义(p < 0.05)。偏心利用率的效应值较小(p = 0.78;η p 2 = 0.01)。反应强度指标和跑纵跳表现出较低的重测信度。结论:两组间无统计学差异。尽管如此,与每种方法的基线值相比,FRST和TRST都显示出对1RM深蹲和CMJ性能的积极影响。因此,飞轮阻力训练可以被认为是传统阻力训练的有效替代,以提高女子篮球运动员的力量水平。
