Objective To investigate and analyze the amount and the type of fluid intake in spring among male college athletics in a university in Beijing, and to provide scientific basis and reference data for fluid intake-related education and formulating adequate water intake.
Methods A simple random sampling method was used to select 109 male sports crowd from a college in Beijing. The information on amount and types of fluid intake were recorded using the validated 7-day fluid specific diary.
Results The median amount of daily fluid intake among participants was 1 789 mL. The number of participants who reached the amount of adequate water intake for Chinese adult residents 60, which accounted for 55.1% of the total participants. There was difference on the amount of fluid intake among different participants after grouped by the quartiles of exercise consumption (χ 2 = 9.20, P = 0.03). There were also differences in the percentage of fluid intake reaching the recommended amount on adequate water intake (χ 2 = 18.27, P =0.04). The median amount of plain water, dairy products, sports beverages, and other sugary beverages were 1 180, 40, 65, and 383 mL, respectively; which accounted for 67.1%, 2.2%, 3.7%, and 22.2% of daily fluid intake. There was difference on the amount of sports beverages among different participants after grouped by the quartiles of BF% ( χ 2 = 8.59, P = 0.04). There was difference on the amount of sports beverages ( χ 2 = 8.25, P = 0.00) and other sugar-sweetened beverages (χ 2 = 8.57, P = 0.02) among different participants after grouped by the quartiles of energy expenditure.
Conclusion Among male sports population in a university in Beijing, the amount of fluid intake differed among different participants after grouped by the quartiles of exercise consumption. As the exercise consumption of participants increased, the water consumption increased. Participants mainly drink plain water, and there were differences on the types of fluid intake among participants with different BF% and different energy expenditure.
【摘要】 目的 调査北京市某髙校男性运动人群春季饮水量及饮水类型, 为制定相应适宜水摄人量提供科学数据。 方法 采用单纯随机抽样的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, 记录调査对象每 次的饮水量和饮水种类。 结果 调査对象每天饮水量中位数为 1 789 mL, 达到中国成年居民水适宜摄人量的为 60 人, 占 总人数的 55.1%。按能量消耗四分位分组后, 不同能量消耗组调査对象之间的饮水量差异有统计学意义 (χ 2 =9.20, P= 0.03), 达到适宜饮水量的百分比差异有统计学意义 (χ 2 =18.27, P= 0.04)。调査对象白水、奶及奶制品、运动饮料、其他含 糖饮料饮用量中位数分别为 1 180, 40, 65 和 383 mL, 分别占饮水量的 67.1%, 2.2%, 3.7% 和 22.2%。不同体脂率组调査对 象的运动饮料饮用量占饮水量的百分比差异有统计学意义 (χ 2 = 8.59, P =0.04)。不同能量消耗组调査对象的运动饮料(χ 2 = 8.25, P = 0.02) 和其他含糖饮料饮用量占饮水量的百分比 (χ 2 = 8.57, P = 0.01) 差异有统计学意义。 结论 北京市某髙校 男性运动人群中, 不同能量消耗组饮水量不同, 能量消耗较髙组饮水量也较髙; 饮水类型主要以饮用白水为主, 不同体脂率 和不同能量消耗组运动人群间的饮水类型存在差异。
