The effects of mild dehydration during ice hockey are well-studied in males but not females. In a randomized, crossover design, 11 female varsity hockey players drank no fluid (1.7% ± 0.3% body mass loss) or water to maintain hydration during simulated-hockey exercise. Core temperature ( < 0.01) and perceived fatigue ( = 0.02) were higher and sprint power lower ( < 0.01) when mildly dehydrated. Thus, mild dehydration may impair hockey performance and thermoregulation while increasing perceived fatigue in females. Female stop-and-go sport athletes may benefit their in-game sprint performance and thermoregulation by following personalized in-game hydration to prevent becoming mildly dehydrated.
在男性中，对冰球运动中轻度脱水的影响已有充分研究，但在女性中则不然。在一项随机交叉设计中，11 名女子大学曲棍球队员在模拟曲棍球运动中既不饮水也不补液（丢失体重的 1.7%±0.3%）以保持水合状态。轻度脱水时核心体温（<0.01）和疲劳感（=0.02）更高，冲刺能力更低（<0.01）。因此，在女性中，轻度脱水可能会损害曲棍球运动表现和体温调节，同时增加疲劳感。女性间断性运动项目运动员通过个性化的场内补水以防止轻度脱水，可能会提高比赛中的冲刺表现和体温调节。
