Objective

The aim of this study was to compare the effects of 12 weeks of traditional resistance training (TRT) or resistance training using Cluster-set (CS) on functional performance and physical fitness of postmenopausal and elderly women.

Methods

Participants (61.1 ± 4.9 years, body mass 64.5 ± 1.8 kg, height 155.7 ± 4.7 cm) were randomized to TRT (n = 35) or CS (n = 31). Anthropometric measures, muscle strength and power, gait speed, core stability, flexibility, and functional performance tests were performed before and after 12 weeks of training. The difference between protocols was the structure of rest intervals. The TRT group performed 120 s of rest between sets of 8 repetitions, while the CS performed 30 s of rest after every 2 repetitions. Two-way ANOVA with repeated measures was applied for each variable and, when needed, the Bonferroni post hoc was used. Statistical significance was set at p < 0.05.

Results

No group by time interaction was found for any variable. Regarding between-moment comparisons, there were significant improvements for 1 repetition maximum (RM) bench press (F = 104.6; η_p² = 0.62; p < 0.001), 1RM leg press (F = 74.6; η_p² = 0.53; p < 0.001), medicine ball throw (F = 64.0; η_p² = 0.26; p < 0.001), standing long jump (F = 27.6; η_p² = 0.30; p < 0.001), countermovement jump (F = 17.4; η_p² = 0.21; p < 0.001), squat jump (F = 23.2; η_p² = 0.26; p < 0.001), plank time (F = 31.6; η_p² = 0.33; p < 0.001), 6 m walking test (F = 18.0; η_p² = 0.22; p < 0.001), sit-to-stand test (F = 20.4; η_p² = 0.24; p < 0.001), sit and reach test (F = 56.8; η_p² = 0.47; p < 0.001) and 2 kg elbow curls (F = 15.9; η_p² = 0.19; p < 0.001).

Conclusion

Considering that both CS and TRT methods were equally effective to improve the physical fitness and functionality of elderly women, the decision of which protocol to use should be based on individual preferences and practical aspects.

与绝经后和老年妇女的传统方法相比，集群式阻力训练可带来类似的功能和力量改善。

目的

这项研究的目的是比较12周传统抵抗训练（TRT）或使用簇集（CS）进行的抵抗训练对绝经后和老年妇女的功能表现和身体健康的影响。

方法

参与者（61.1±4.9岁，体重64.5±1.8 kg，身高155.7±4.7 cm）被随机分为TRT（n = 35）或CS（n = 31）。训练前后十二周进行人体测量，肌肉力量和力量，步态速度，核心稳定性，柔韧性和功能性能测试。协议之间的区别是休息间隔的结构。TRT组在8个重复的集合之间执行了120 s的休息，而CS每2个重复执行了30 s的休息。对每个变量应用具有重复测量的双向ANOVA，并在需要时使用Bonferroni post hoc。统计学显着性设定为p <0.05。

结果

找不到任何变量的按时间分组交互。关于瞬间之间的比较，对于1次最大重复（RM）卧推（F = 104.6; _ηp ²  = 0.62; p <0.001），1RM腿部按压（F = 74.6; _ηp ²  = 0.53; p <0.001），药球投掷（F = 64.0; _ηp ²  = 0.26; p <0.001），站立跳远（F = 27.6; _ηp ²  = 0.30; p <0.001），反向运动跳跃（F = 17.4;η _p ²  = 0.21; p <0.001），蹲跳（F = 23.2; _ηp ²  = 0.26; p <0.001），浮板时间（F = 31.6; _ηp ²  = 0.33; p <0.001），6 m行走测试（F = 18.0; _ηp ² = 0.22; p <0.001），从站到站测试（F = 20.4; _ηp ²  = 0.24; p <0.001），从站到站测试（F = 56.8; _ηp ²  = 0.47; p <0.001）和2 kg肘卷曲（F ＝ 15.9；_ηp ²  ＝ 0.19； p ＜0.001）。

结论

考虑到CS和TRT方法在改善老年妇女的身体健康和功能方面均同样有效，因此应根据个人的喜好和实际情况来决定使用哪种协议。
