The value of mean skin temperature as an estimate of energy expenditure was verified in a sample of 10 normal-weight adult male subjects. Measurements were carried out with thermometric probes under conditions of rest and environmental thermoneutrality. Total heat losses were then calculated through a computerized complex mathematical formula. The value for mean energy expenditure obtained in this manner (100.2 +/- 7.02 kcal/h) is extremely close to the value for theoretical metabolism derived from the predictive equations in the literature (95.01 +/- 6.14). This verification of the validity of transforming cutaneous temperature data into energy expenditure, in accurately standardized experimental conditions, confirms the importance that the value of mean skin temperature, in the area of variability among individuals, can have in conditioning the energy balance at different levels, for a given caloric intake and with all other parameters being equal (age, sex, physical activity). In this connection, these results suggest that skin temperature may play a role in the pathogenesis of obesity.
在10名正常体重成年男性受试者的样本中,验证了平均皮肤温度作为能量消耗估计值的有效性。在休息和环境热中性条件下,使用温度探头进行测量。然后通过计算机化的复杂数学公式计算总热损失。以这种方式获得的平均能量消耗值(100.2±7.02千卡/小时)与文献中预测方程得出的理论代谢值(95.01±6.14)极为接近。在精确标准化的实验条件下,将皮肤温度数据转化为能量消耗的有效性验证,证实了在个体间变异性范围内,平均皮肤温度值对于在给定热量摄入且所有其他参数相同(年龄、性别、身体活动)的情况下,在不同水平调节能量平衡可能具有的重要性。就此而言,这些结果表明皮肤温度可能在肥胖症的发病机制中起作用。
