Brandt, R, Bevilacqua, GG, and Andrade, A. Perceived sleep quality, mood states, and their relationship with performance among Brazilian elite athletes during a competitive period. J Strength Cond Res 31(4): 1033-1039, 2017-We described the perceived sleep quality and mood states of elite athletes during a competitive period, and clarified their relationship to athletes' sport performance. Participants were 576 Brazilian elite athletes (404 men and 172 women) of individual and team sports. Mood states were evaluated using the Brunel Mood Scale, whereas perceived sleep quality was evaluated using a single question ("How would you evaluate the quality of your sleep in the last few days?"). Evaluations of mood state and sleep quality were performed up to 60 minutes before national and international sports competitions began. Descriptive and inferential statistics (including logistic regression) were used to evaluate the relationship of sleep quality and mood states with performance (i.e., winning or losing). Athletes typically had good sleep quality and mood states similar to the Iceberg profile (i.e., high vigor and low tension, depression, anger, fatigue, and mental confusion). The Wald test revealed that sleep, anger, tension, and vigor predicted athletes' performance. Specifically, poor sleep quality and low vigor and anger decreased the odds of winning, whereas higher tension increased these odds. The Hosmer-Lemeshow test indicated that the results were sufficiently generalizable. Overall, we observed a significant relationship between sleep and mood states, which in turn both significantly influenced athletes' sports performance. Thus, coaching staff and athletes should monitor athletes' sleep quality before competitions to ensure athletes are in the optimal condition for performance.
布兰特、R、贝维拉夸、GG以及安德拉德、A。竞技期巴西精英运动员的睡眠质量感知、情绪状态及其与运动表现的关系。《力量与体能研究杂志》31(4):1033 - 1039，2017年 - 我们描述了精英运动员在竞技期的睡眠质量感知和情绪状态，并阐明了它们与运动员运动表现的关系。研究对象为576名巴西个人和团体运动项目的精英运动员（404名男性和172名女性）。使用布鲁内尔情绪量表评估情绪状态，而睡眠质量感知则通过一个单一问题进行评估（“你如何评价过去几天你的睡眠质量？”）。在国内和国际体育比赛开始前60分钟内对情绪状态和睡眠质量进行评估。使用描述性和推断性统计（包括逻辑回归）来评估睡眠质量和情绪状态与运动表现（即获胜或失败）之间的关系。运动员通常具有良好的睡眠质量和类似于冰山模型的情绪状态（即高活力和低紧张、抑郁、愤怒、疲劳及精神混乱）。 Wald检验显示，睡眠、愤怒、紧张和活力可预测运动员的表现。具体而言，睡眠质量差、活力低和愤怒会降低获胜几率，而较高的紧张程度则会增加获胜几率。Hosmer - Lemeshow检验表明结果具有充分的普遍性。总体而言，我们观察到睡眠与情绪状态之间存在显著关系，而这两者又都对运动员的运动表现产生显著影响。因此，教练团队和运动员应在比赛前监测运动员的睡眠质量，以确保运动员处于最佳表现状态。
