The purpose of this study was to characterize the hydration habits and fluid balance of female para-ice hockey players.
Fifteen players [5 defense (D), 8 forwards (F), and 2 goalies (G)] volunteered to participate in the study (age: 26.3 ± 10.9 y; ht:155 ± 11 cm; arm length: 65 ± 8 cm; leg length: 88 ± 11 cm; trunk length: 66 ± 14 cm). Players were weighed pre- and postgame, while fluid intake and individual playing time (PT) was monitored throughout the game.
On average, athletes arrived hydrated to the game (USG 1.019 ± 0.006) with 40% of players arriving dehydrated (USG >1.020). Mean playing time for forwards was 11:47-28:49 min:s (18:52 ± 5:48 min:s) and for defence 13:10-18:24 min:s (15:10 ± 2.05 min:s). Sweat loss was 0.96 ± 0.64 L (0.10-2.50 L) which exceeded net fluid intake (0.61 ± 0.37 L). Mean BM loss was 0.44 ± 0.9% (-2.1 to +0.9%) with 4 of 15 players (2 D, 1 F, 1 G) losing between 1.4 and 2.1% BM. Players preferred to drink water during the game compared to a carbohydrate electrolyte solution.
60% of athletes arrived hydrated to the game and drank enough fluid to prevent a BM loss <1%. Of note is that 40% of players arrived at the arena mildly dehydrated based on USG, and despite abundant opportunities to drink fluid during the game, 25% of players lost >1.3% BM due to sweat loss which may compromise physical and cognitive performance.
本研究旨在描述女子冰球运动员的水合习惯和体液平衡情况。
15名运动员[5名后卫（D）、8名前锋（F）和2名守门员（G）]自愿参与本研究（年龄：26.3±10.9岁；身高：155±11厘米；臂长：65±8厘米；腿长：88±11厘米；躯干长度：66±14厘米）。在赛前和赛后对运动员进行称重，同时在整个比赛过程中监测液体摄入量和个人比赛时间（PT）。
平均而言，运动员在比赛开始时处于水合状态（尿比重1.019±0.006），40%的运动员到达时处于脱水状态（尿比重>1.020）。前锋的平均比赛时间为11分47秒至28分49秒（18分52秒±5分48秒），后卫为13分10秒至18分24秒（15分10秒±2.05分钟）。出汗量为0.96±0.64升（0.10至2.50升），超过净液体摄入量（0.61±0.37升）。平均体重减轻为0.44±0.9%（-2.1%至+0.9%），15名运动员中有4名（2名后卫、1名前锋、1名守门员）体重减轻1.4%至2.1%。与碳水化合物电解质溶液相比，运动员在比赛期间更喜欢喝水。
60%的运动员在比赛开始时处于水合状态，并饮用了足够的液体以防止体重减轻<1%。值得注意的是，根据尿比重，40%的运动员到达赛场时轻度脱水，并且尽管在比赛中有大量饮水机会，但25%的运动员因出汗导致体重减轻>1.3%，这可能会影响身体和认知表现。
