在目前的研究中，12名有氧健康和12名久坐不动的老年男性接受了两次夜间多导睡眠监测(PSG)研究。对照组的PSG是在没有有氧运动的第二天进行的，而运动后的PSG的研究是在下午的精力性有氧运动之后进行的。除了得出通常的睡眠参数外，还使用计算机评分程序来计算每一次PSG追踪中的单个脑电(EEG)慢波的数量。多因素和单因素分析显示，与久坐不动的受试者相比，配合组入睡潜伏期更短，入睡后觉醒时间更短，离散睡眠次数更少，睡眠阶段转换更少，阶段1睡眠更少，睡眠效率更高，总慢波更多。尽管没有发现急性运动挑战的主要影响，但事后的分析表明，运动期间高水平的体温预示着健康和久坐的受试者睡眠碎片的增加。这些发现初步支持了运动和健身可能对老年男性睡眠有重大影响的观点。然而，结果也表明，单一运动挑战导致的高水平体温可能会产生不利影响。对本研究的意义进行了讨论，并对未来的研究提出了建议。
In the current study 12 aerobically fit and 12 sedentary older men underwent two nocturnal polysomnographic (PSG) studies. A control PSG was conducted following a day without aerobic activity, whereas a postexercise PSG study was conducted following an afternoon session of exhaustive aerobic exercise. In addition to deriving usual sleep parameters, a computer scoring program was used to count the number of individual electroencephalographic (EEG) slow waves in each PSG tracing. Multivariate and univariate analyses showed that the fit subjects had shorter sleep onset latencies, less wake time after onset, fewer discrete sleep episodes, fewer sleep stage shifts during the initial portion of the night, less stage 1 sleep, a higher sleep efficiency and more total slow waves during both PSGs than did the sedentary subjects. Although no main effects were found for the acute exercise challenge, post hoc analyses showed that high levels of body heating during exercise predicted increased sleep fragmentation for both fit and sedentary subjects. These findings provide initial support for the contention that exercise and fitness may have significant effects on the sleep of older men. However, results also suggest that high levels of body heating resulting from a single exercise challenge may have adverse effects. Implications of the study are discussed and suggestions for future research are provided.
