Resumo
The purpose of this study was to evaluate the influence of a session of resistance training on the sleep patterns of elderly people. Forty men aged 65-80 years who were sedentary and clinically healthy were divided into two groups: the control group (n = 18) and the resistance group (n = 22). Both groups underwent two polysomnography tests, one at baseline and another after either a resistance training session (the resistance group) or no physical exercise (the control group). the resistance training session was based on 60% of one repetition maximum (a test that assesses the maximum force). We observed that the frequency with which the control group awoke (arousal index) increased from 16.29 +/- A 6.06 events/h to 20.09 +/- A 6.9 events/h, and in the resistance group, it decreased from 22.27 +/- A 11 events/h to 20.41 +/- A 8.57 events/h (t = 2.10 and p = 0.04). for stage-1 sleep, there was an increase from 4.96% at baseline to 5.40% in the control group, and there was a decrease in the resistance group from 8.32 to 6.21% after the exercise session (t = 2.12 and p = 0.04). A session of resistance training at 60% of one repetition maximum was able to modify the sleep pattern in men aged 65-80 years, suggesting that physical exercise has a modest influence on sleep consolidation.
