未经证实:已知进行性体液流失对运动和认知表现的影响是由于暴露于环境热应激所致,形态学因素,和有限的液体补充。运动员需要恢复失去的身体水分。然而,运动员在运动过程中可能无法保持充足的水分。本系统综述研究了水分不足和液体平衡对运动员认知功能的影响。
未经授权:PubMed,体育讨论,并在Ebsco数据库中搜索有关水合不足的研究报告,运动中的液体平衡和热量对认知表现的影响。多个短语,包括水合,脱水,流体平衡,心情,认知,警惕,警惕决策,和大脑被探索。研究的参与者在运动过程中要么接受液体,要么没有接受液体。
UNASSIGNED:来自24篇文章的24项试验(n=493名参与者)符合纳入标准。严重的水合不足,在16种出版物中一致报道了>2%的体重损失。五篇文章指出,水分不足与热应激和有限的液体摄入(3-5%的体重损失)有关,损害了认知能力。情绪紊乱,疲劳,感知劳累的评分不断补充了认知上的低水合损害。
UNASSIGNED:研究结果表明,在较高水平的3-5%体重损失时,水分不足会损害认知表现和情绪。然而,在个人和团队运动中获得水分不足和液体平衡的运动特定认知协议仍然模棱两可。
UNASSIGNED: The effects of progressive body fluid loss on athletic and cognitive performance are known to result from exposure to environmental heat stress, morphologic factors, and limited fluid replenishment. Athletes need to restore lost body water. However, athletes may fail to maintain euhydration during exercise. This systematic review investigated
hypohydration and fluid balance effects on an athlete\'s cognitive function.
UNASSIGNED: The PubMed, Sports Discuss, and Ebsco databases were searched for studies reporting on hypohydration, fluid balance and heat on cognitive performance in sport. Multiple phrases including hydration, dehydration, fluid balance, mood, cognition, vigilance, decision making, and brain were explored. Participants in the studies did either receive fluid or did not receive fluid during exercise.
UNASSIGNED: Twenty-four trials (n=493 participants) from 24 articles met the inclusion criteria. Significant
hypohydration, >2% body mass loss was reported consistently in 16 publications. Five articles where
hypohydration was associated with heat stress and limited fluid intake (3-5% body mass loss) impaired cognitive performance. Mood disturbance, fatigue, and ratings of perceived exertion constantly complemented hypohydration impairment on cognition.
UNASSIGNED: Findings show that
hypohydration impairs cognitive performance and mood at higher levels of 3-5% body mass loss. However, sport-specific cognitive protocols of accessing
hypohydration and fluid balance in individual and team sports remain equivocal.
