OBJECTIVE
To investigate the hydration status pre- and post-training among university athletes using urine color and weight loss as indicators.
PARTICIPANTS
Participants were 52 university athletes training for campus games in a developing country.
METHODS
Pre- and post-training urine specimens were compared with a standard urine color scale. Paired t tests were used to compare urine color and difference in body mass pre- and post-training.
RESULTS
The mean age of the athletes was 22.87 ± 3.21. A statistically significance difference (p < .01) was observed between pre- (4.31 ± 1.75) and post- (5.67 ± 1.45) training urine color values for males. Hydration status and weight post-training were statistically significantly different both at the level of p < .01.
CONCLUSIONS
The results suggest that there is a link between urine color and body mass difference among the student athletes tested. Exercise increases hypohydration due to fluid losses, and therefore attention should be given to fluid supplementation and individualization of fluid intake for each athlete.
目的
以尿液颜色和体重减轻为指标，调查大学生运动员训练前后的水合状态。
参与者
参与者为发展中国家一所大学中52名参加校园运动会训练的运动员。
方法
将训练前后的尿液样本与标准尿液颜色对照表进行比较。采用配对t检验来比较尿液颜色以及训练前后体重的差异。
结果
运动员的平均年龄为22.87±3.21岁。男性训练前（4.31±1.75）和训练后（5.67±1.45）尿液颜色值之间存在统计学显著差异（p<0.01）。训练后的水合状态和体重在p<0.01水平上均存在统计学显著差异。
结论
结果表明，在所测试的学生运动员中，尿液颜色与体重差异之间存在联系。运动因液体流失会增加水合不足，因此应关注液体补充以及为每位运动员制定个性化的液体摄入量。
