文题释义：

排水量：是指人体通过排尿、粪便、排汗以及通过皮肤和呼吸途径的非感蒸发的水排出，正常情况下人体排水量和水摄入量处于动态平衡。处于坐姿位的普通成年人一日排水量为2.0-3.0 L，排水量受到年龄、身体组成、温湿度、身体活动水平等因素影响。
能量代谢测试舱：基于开放式间接测热法的密闭舱室，通过连续测量舱内O2和CO2的浓度来计算舱内受试者O2消耗量和CO2产生量，从而计算能量消耗量。可以通过能量代谢测试舱测量并计算一日总能量消耗和基础能量消耗的比值，获取一日身体活动水平。

 

背景：目前没有连续而精确的测量特定活动强度下的一日排水量的研究。
目的：测量分析青年男性在中等活动强度的一日排水量，为每日水需求量提供参考。
方法：20名男性受试者在人体能量代谢测试舱内进行23 h中等强度活动，使用高精度人体体质量秤测算23 h排湿量和排尿量，结果换算为一日排水量来确定一日需水量。同时计算一日单位体质量排湿量、单位瘦体质量排湿量和单位体表面积排湿量。

结果与结论：①青年男性一日平均排水量为(3 339.7±509.9) g，排尿量为(1 982.9±449.5) g，排湿量为(1 356.7±215.6) g，饮水量和排水量呈正相关(r=0.616，P < 0.05)。②每日单位体质量排湿量为(21.0±3.6) g/kg，每日单位瘦体质量排湿量为(25.8±3.9) g/kg，每日单位体表面积排湿量为(799.4±129.4) g/m2。③青年男性在中等活动强度下的一日排水量约为3 340 g，排水量受到摄入量影响，摄入水越多排出的水也越多。

Abstract:

BACKGROUND: No studies currently focus on the measurement of daily water loss under certain physical activity level continuously and precisely.
OBJECTIVE: To provide evidence for daily water requirement in Chinese young men based on the measurement of the daily water loss in Chinese young men under moderate physical activity.
METHODS: Twenty male subjects were enrolled, and 23-hour whole-body sweat loss and urine output were measured using high-precision body weighting scale in whole-room indirect calorimeter. The results were converted to daily (24-hour) water requirement to determine the daily water requirement. Daily whole-body sweat loss per unit body weight, daily whole-body sweat loss per unit fat free mass and daily whole-body sweat loss per unit surface area were calculated.
RESULTS AND CONCLUSION: In Chinese young men, daily water loss was (3 339.7±509.9) g, daily urine output was (1 982.9±449.5) g and daily whole-body sweat loss was (1 356.7±215.6) g. There was a linear correlation between water intake and water loss (r=0.616, P < 0.05). Daily whole-body sweat loss per unit body weight was (21.0±3.6) g/kg, daily whole-body sweat loss per unit fat free mass was  (25.8±3.9) g/kg and daily whole-body sweat loss per unit surface area was (799.4±129.4) g/m2. Daily water requirement of Chinese young men under moderate physical activity is approximately 3 340g, and moreover, water loss increases with the increase of water intake.
