The primary purpose of this investigation was to determine the impact of altering the set structure during an 8-week resistance training program on anthropometric, hormonal, and strength power characteristics. Thirty female volleyball players were recruited for participation and then randomly assigned to 1 of 3 resistance training groups: (i) cluster sets (CRT; n = 10), (ii) traditional sets (TRT; n = 10), or (iii) control (CON; n = 10). All athletes were evaluated for thigh and arm circumference, vertical jump, 20-m sprint, 4 × 9-m shuttle-run, 1-repetition maximum (1RM) back squat, bench press, military press, and deadlift prior to and after an 8-week periodized training intervention. Blood samples were taken before and after the 8-week training period to evaluate resting testosterone, cortisol, and insulin-like growth factor 1 responses to the training period. After 8 weeks of training the CRT group displayed a small but significant improvement in vertical jump (CRT: effect size (ES) = 038, 7.1%) performance when compared with the TRT group (ES = 0.34, 5.6%). Both the CRT and TRT training interventions resulted in very large increases in the 1RM squat (CRT: 8.4% ± 1.2%; TRT: 7.3% ± 0.6%), bench press (CRT: 8.3% ± 2.0%; TRT: 8.7% ± 1.9%), military press (CRT: 5.7% ± 1.2%; TRT: 5.5% ± 1.6%), and deadlift (CRT: 8.2% ± 1.6%; TRT: 8.3% ± 2.2%). There were no significant differences in 20-m sprint or 4 × 9-m shuttle run times between the CRT, TRT, and CON groups. These results suggest that cluster sets allow for greater improvements in vertical jump performance and equal improvements in strength gains to those seen with traditional sets.
本研究的主要目的是确定在 8 周抗阻训练计划中改变设定结构对人体测量学、激素和力量特征的影响。招募了 30 名女性排球运动员参与，并随机分配到 3 个抗阻训练组之一：（i）集群组（CRT；n=10）、（ii）传统组（TRT；n=10）或（iii）对照组（CON；n=10）。所有运动员在 8 周周期训练干预前后评估大腿和手臂周长、垂直跳跃、20 米冲刺、4×9 米穿梭跑、1 次重复最大重量（1RM）深蹲、卧推、推举和硬拉。在 8 周训练期间前后采集血液样本，以评估训练期间静息睾酮、皮质醇和胰岛素样生长因子 1 的反应。经过 8 周的训练，与 TRT 组（ES=0.34，5.6%）相比，CRT 组的垂直跳跃（CRT：效应大小（ES）=0.38，7.1%）表现略有但显著提高。CRT 和 TRT 训练干预均导致 1RM 深蹲（CRT：8.4%±1.2%；TRT：7.3%±0.6%）、卧推（CRT：8.3%±2.0%；TRT：8.7%±1.9%）、推举（CRT：5.7%±1.2%；TRT：5.5%±1.6%）和硬拉（CRT：8.2%±1.6%；TRT：8.3%±2.2%）的非常大的增加。CRT、TRT 和 CON 组之间的 20 米冲刺或 4×9 米穿梭跑时间没有显著差异。这些结果表明，集群组允许垂直跳跃表现更大的提高，并且力量增益的提高与传统组相同。
