This comparative study focused on chronic exercise training, menstrual cycle, menstruation, and sex related with slow-wave sleep and energy expenditure (EE) during sleep in runners and controls. Participants included 26 highly trained runners (9 males, 8 amenorrheic females, and 9 menstruating females) and 20 controls (10 males and 10 menstruating females) aged 21 ± 2 years. Sleeping metabolic rate and EE during slow-wave sleep were 2.7% and 3.9% higher in the luteal than the follicular phase for female runners. Significant interactions were found between the 8-h time course adjusted EE and menstruation, exercise training, and sex. Sleep stage durations did not differ between groups. Interestingly, amenorrheic runners did not suppress sleeping and overnight metabolic rates, suggesting that EE in sleep may not be a causative factor for amenorrhea in runners. This study highlights the complex relationship between chronic exercise, menstrual cycle, and sex on EE during sleep.
这项比较研究聚焦于长期运动训练、月经周期、月经以及与跑步者和对照组睡眠期间慢波睡眠和能量消耗（EE）相关的性别因素。参与者包括26名训练有素的跑步者（9名男性、8名闭经女性和9名经期女性）以及20名对照组人员（10名男性和10名经期女性），年龄为21±2岁。对于女性跑步者，黄体期睡眠代谢率和慢波睡眠期间的能量消耗比卵泡期分别高出2.7%和3.9%。在经过8小时时间进程调整的能量消耗与月经、运动训练和性别之间发现了显著的交互作用。各组之间睡眠阶段时长并无差异。有趣的是，闭经的跑步者并未抑制睡眠和夜间代谢率，这表明睡眠中的能量消耗可能不是跑步者闭经的一个致病因素。这项研究凸显了长期运动、月经周期和性别在睡眠期间能量消耗方面的复杂关系。
