We analyzed the effect of an 8-week strength training (ST) program on the rate of force development (RFD) and electromyographic activity (EMG) in older women. Seventeen women (M age = 63.4 years, SD = 4.9) without previous ST experience were randomly assigned to either a control (n=7) or training (n=10) group. A leg-press isometric test was used for assessment. ST (three sessions/ week, three sets of 10-12 repetition maximum, five different exercises) induced significant increases (p < .05) on peak RPD (48.4%) and on RFD) and EMG of vastus medialis at time intervals of 0-50, 0-100, 0-150, and 0-200 ms (41.1-69.2% and 43.8-64.3%, respectively). Therefore, ST resulted in favorable changes in neuromuscular responses in older women.
我们分析了 8 周力量训练（ST）方案对老年女性的力量发展速率（RFD）和肌电图活动（EMG）的影响。17 名无先前 ST 经验的女性（M 年龄=63.4 岁，SD=4.9）被随机分配到对照组（n=7）或训练组（n=10）。使用腿蹬等长测试进行评估。ST（每周三次，三组 10-12 次重复最大，五种不同的运动）导致峰值 RPD（48.4%）和 RFD）以及股直肌在 0-50、0-100、0-150 和 0-200 毫秒的间隔的 EMG 显著增加（p<.05）（分别为 41.1-69.2%和 43.8-64.3%）。因此，ST 导致老年女性的神经肌肉反应发生了有利的变化。
