We investigated the effect of a 12-week physical training programme on the sleep of nine unfit women. Data were collected at 0, 4, 8 and 12 weeks of the training programme. Changes in fitness were assessed by changes in maximal oxygen consumption (VO2max) and onset of blood lactate turn point (LTP). Lean body mass (LBM) was calculated from total body potassium measurements. The all-night sleep recordings were made following days during which the subjects carried out their normal daily routines and did no extra exercise. Although cardiorespiratory fitness improved significantly as indicated by an increase in both VO2max and LTP, there was no change in LBM. The improvement in cardiorespiratory fitness did not result in any changes in the sleep parameters measured. Other workers have reported an improvement in sleep quality in eight army recruits during their basic training. The male recruits showed improved cardiorespiratory fitness and an increase in muscle bulk. These results suggest that increased fitness only facilitates sleep when there is an associated increase in LBM. Alternatively it may be that the response of sleep to improved fitness is sex-linked.
我们研究了一项为期12周的体育训练计划对9名身体状况不佳的女性睡眠的影响。在训练计划的第0、4、8和12周收集数据。通过最大耗氧量（VO2max）和血乳酸拐点（LTP）的变化来评估身体状况的变化。瘦体重（LBM）通过全身钾测量来计算。整夜睡眠记录是在受试者进行正常日常活动且没有额外运动的日子之后进行的。尽管VO2max和LTP的增加表明心肺功能显著改善，但LBM没有变化。心肺功能的改善并未导致所测量的睡眠参数发生任何变化。其他研究人员报告说，八名新兵在基础训练期间睡眠质量有所改善。男性新兵的心肺功能得到改善，肌肉量增加。这些结果表明，只有当LBM相关增加时，体能的提高才会促进睡眠。或者，睡眠对体能改善的反应可能与性别有关。
