          Objective To investigate and analyze the fluids intake, urine output and hydration status during spring among male college athletics from one university in Beijing, and to provide scientific evidence for launching targeted health education.

          Methods A simple random sampling method was used to select 109 male students in college with habit of exercise.Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire. The water from food was assessed by the duplicate portion method and the weight method. The urine samples of 24-hour was collected for 3 consecutive days, and the volume, osmolality and specific gravity of urine were measured. The energy expenditure in exercise was estimated by using the exercise plan.

          Results The median drinking fluids intake, water from food, total fluids intake and urine volume were 1 789, 955, 2 701, 850 mL/d, respectively. 15.6% of the subjects were in proper hydration status, and 43.1% of the subjects were in dehydration. The differences between drinking fluids intake, water from food, total fluids intake and urine volume of subjects in the different BMI and BF% levels were not significant ( P>0.05). The differences between drinking fluids intake and total fluids intake of subjects in the different energy expenditure in exercise levels were significant (χ 2 =9.20, 8.43, P<0.05).

          Conclusion Comparing with the normal college students, the drinking fluids intake and total fluids intake of male sports people were higher, the volume of urine was lower, and the hydration status was worse. The targeted health education about water intake was recommended.


          【摘要】 目的 调査并分析北京市某髙校男性运动人群春季饮水量、排尿量与水合状态, 为后期开展针对性的饮水 宣教提供科学依据。 方法 采用简单随机抽样方法抽取北京市某髙校男性运动人群 109 名, 采用连续 7 d 24 h 饮水记录 法调査其饮水量, 采用双份饭法与称重法, 对研究对象食用的食物进行称重采样送检, 调査其食物水摄人量, 收集调査对象 连续 3 d 的尿液, 记录其排尿量并进行检测, 使用训练计划估算其每周运动训练的能量消耗。 结果 调査对象整体每日饮 水量的中位数为 1 789 mL, 每日食物水摄人量的中位数为 955 mL, 每日总水摄人量的中位数为 2 701 mL, 每日 24 h 排尿量 的中位数为 850 mL, 15.6% 的研究对象处于适宜水合状态, 43.1%处于脱水状态。不同体脂率 (BF%)、体质量指数 (BMI) 等级的研究对象每日饮水量、食物水摄人量、总水摄人量与排尿量差异均无统计学意义 ( P 值均>0.05)。不同运动训练能 量消耗等级的研究对象每日饮水量、总水摄人量差异均有统计学意义 (χ 2 值分别为 9.20, 8.43, P值均<0.05)。 结论 相比 普通人群, 北京市某髙校男性运动人群的每日饮水量与总水摄人量较髙, 排尿量较低, 且存在水合状态较差的现象, 应对其 进行针对性的饮水宣教。
