Association between distal-proximal skin temperature gradient during sleep and aerobic capacity

在睡眠开始后观察到直肠温度的下降。测量第一个睡眠周期远端（拇指大鱼际和足底区）-近端（锁骨下窝、肚脐和大腿）皮肤温度梯度作为热损失指数。第一睡眠周期热损失指数与有氧能力评分呈显著正相关。目前的研究结果表明，有氧能力的下降增强了睡眠期间较低的远端热损失能力。有氧运动训练（50%HRR, 30min， 3次/周，4周）对第一睡眠周期热损失指数无显著改善。

The decline in the rectal temperature was observed after sleep onset. The distal (thenar of the thumb and the plantar area) - proximal (infraclavicular fossa, the navel, and the thigh) skin temperature gradient during first sleep cycle was measured as the heat loss index. There is a significant positive correlation between heat loss index in the first sleep cycle and the aerobic capacity score. The present findings suggest that a decline in aerobic capacity enhances a lower distal heat loss capacity during sleep. The heat loss index during the first sleep cycle was not improved significantly by aerobic exercise training (50%HRR, 30min, 3 times/week, 4 weeks).
