熬夜行为对运动员心理认知的影响

Effects of Staying up Late on Athletes’ Psychological Cognition

本研究旨在探讨熬夜行为对运动员24h中心理认知指数的影响。应用Karolinska嗜睡量表(KSS)和睡眠监控,采取早睡型(ECTs)、晚睡型(LCTs)分组,对被试在24 h中(次日08:00 h和14:00 h、18:00 h)进行心理认知表现测试。结果:我们发现ECTs和LCTs在日间嗜睡、精神运动警觉、执行功能方面有明显的差异。结论:熬夜行为会影响运动员的认知能力;LCTs在次日08:00精神运动警觉、执行功能较弱;良好的作息时间可提高运动员的运动成绩。

This study aimed to investigate the effect of day and night behavior on the psychological cognitive index of athletes during 24 hours. The Karolinska Sleepiness Scale (KSS) and sleep monitoring were used to group early-sleeping (ECTs) and late-sleeping (LCTs) groups. The subjects were in 24 h (the next day at 08:00 h and 14:00 h, 18:00 h) conduct a psychological cognitive performance test. Results: We found significant differences in ECTs and LCTs in terms of daytime sleepiness, psychomotor alertness, and executive function. Conclusion: Day and night behavior will affect the cognitive ability of athletes;LCTs will be less alert and perform better at 08:00 the next day;good working hours can improve athletes’ athletic performance.
