Resumo
We analyzed the effect of an 8-week strength training (ST) program on the rate of farce 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 RFD (48.4%) and on RID 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.
