概括

睡眠不足会影响运动员的压力和认知功能. 睡眠不足后Stroop任务性能降低预测竞争成功降低,突出了运动员认知压力管理的重要性.

科学领域:

运动科学运动科学运动科学
神经科学是一个神经科学.
心理学心理学心理学

背景情况:

有效的压力管理对于体育表现至关重要.
睡眠不足 (SD) 加剧了压力,改变了运动员的认知/情绪状态,可能会影响比赛结果.
关于SD诱导的长期运动表现变化的预测价值的证据有限.

研究的目的:

调查24小时睡眠不足 (SD) 对运动员压力水平的影响.
为了确定SD后的认知和情绪变化是否可以预测大约1.5个月的体育表现.
探索压力标志物,认知功能和运动结果之间的关系.

主要方法:

65名冬季运动运动员 (大学和职业) 接受了评估.
生理 (焦虑,皮质醇) 和认知 (Stroop,Go/No-Go,CRT,IGT) 测量在基线,24小时SD后和比赛期间进行.
记录了与事件相关的潜力 (ERP),并对表现进行了分类 (超常,正常,异常).

主要成果:

24小时SD增加了焦虑和皮质醇水平,与官方比赛中的水平相匹配.
在SD之后不一致的Stroop响应的减少与随后的竞争表现有负面关联.
P3元件,特别是中叶的三角频率,显著调解了Stroop表现和运动结果之间的关系.

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Correlations

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
