It seems that dehydration may impair decision-making performance in athletes.
This study aimed to investigate the influence of dehydration on passing decision-making performance in soccer players.
Participants were 40 male soccer players (M = 22.3 ± 2.3 years) who agreed to participate in the study and were randomly assigned to the following conditions: control (CON), dehydration (DEH), and euhydration (EUH). The players played in 2 games of 90 min in duration (2 45-min halves) followed by 2 15-min halves (overtime) with and without proper hydration. The Game Performance Assessment Instrument (GPAI) was considered for the analysis of passing decision making.
The GPAI analysis indicated effective reduction in the decision-making index in the DEH condition compared with the EUH and CON conditions, F(2, 38) = 31.4, p < .05, ES = 0.8.
In conclusion, dehydration may be considered a mediating factor in the passing decision-making performance of male soccer athletes.
脱水似乎可能会损害运动员的决策表现。
本研究旨在调查脱水对足球运动员传球决策表现的影响。
参与者为40名男性足球运动员（平均年龄M = 22.3 ± 2.3岁），他们同意参与本研究，并被随机分配到以下条件组：对照组（CON）、脱水组（DEH）和正常水合组（EUH）。球员们进行了两场时长90分钟（上下半场各45分钟）的比赛，之后是两场15分钟的半场比赛（加时赛），比赛中有的有适当水合，有的没有。使用比赛表现评估工具（GPAI）来分析传球决策。
GPAI分析表明，与EUH组和CON组相比，DEH组的决策指数有效降低，F(2, 38) = 31.4，p <.05，效应量ES = 0.8。
总之，脱水可能被视为男性足球运动员传球决策表现的一个中介因素。
