OBJECTIVE
This study aimed to compare the effects of two frequencies of high-speed resistance training (HSRT) on physical performance and quality of life of older women.
METHODS
A total of 24 older women participated in a 12-week HSRT program composed of either two or three sessions/week (equated for volume and intensity). Women were randomized into three arms: a control group (CG, n=8), a resistance training group performing two sessions/week (RT2, n=8), and a resistance training group performing three sessions/week (RT3, n=8). The training program for both experimental groups included exercises that required high-speed concentric muscle actions.
RESULTS
No baseline differences were observed among groups. Compared with the CG, both training groups showed similar small to moderate improvements (<0.05) in muscle strength, power, functional performance, balance, and quality of life.
CONCLUSION
These results suggest that equated for volume and intensity, two and three training sessions/week of HSRT are equally effective for improving physical performance and quality of life of older women.
目的
本研究旨在比较两种频率的高速抗阻训练（HSRT）对老年女性身体机能和生活质量的影响。
方法
共有24名老年女性参与了一项为期12周的HSRT计划，该计划由每周两次或三次训练课程组成（训练量和强度相等）。女性被随机分为三组：对照组（CG，n = 8）、每周进行两次训练课程的抗阻训练组（RT2，n = 8）和每周进行三次训练课程的抗阻训练组（RT3，n = 8）。两个实验组的训练计划都包括需要高速向心肌肉动作的练习。
结果
各组之间未观察到基线差异。与CG组相比，两个训练组在肌肉力量、功率、功能表现、平衡和生活质量方面均表现出相似的小到中等程度的改善（<0.05）。
结论
这些结果表明，在训练量和强度相等的情况下，每周两次和三次的HSRT训练对改善老年女性的身体机能和生活质量同样有效。
