As opposed to adults, infants were found to have 5-fold differences in values of heat production per unit of mass and unit of body surface. Animals of the same age have these differences not over 20-50%. Newborn mature infants could have these differences to reach 50-60%. The data obtained suggest significant differences in the efficiency coefficient values for muscles contractile activity to play the role of the mechanism of heat production control in chemical thermoregulation and postnatal formation of the constancy of main (standard) metabolism.
与成年人不同，婴儿每单位质量和单位体表面积的产热值存在5倍的差异。相同年龄的动物这种差异不超过20%-50%。新生成熟婴儿的这种差异可能达到50%-60%。所获得的数据表明，在化学体温调节以及主要（标准）代谢恒定性的产后形成过程中，肌肉收缩活动的效率系数值存在显著差异，肌肉收缩活动在产热控制机制中发挥作用。
