Perceived Sleep Quality, Mood States, and Their Relationship With Performance Among Brazilian Elite Athletes During a Competitive Period

Abstract

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.

Psychological Profile, Competitive Anxiety, Moods and Self-Efficacy in Beach Handball Players

“…However, the relationships between the set of constructs proposed in this research had not been analyzed, and they were also differentiated by gender. For this reason, the obtained results make a significant contribution to beach handball and allow us to better understand psychological aspects that have been considered relevant for athletes' performance in previous investigations [8,9,16,29].…”

“…Another of the psychological constructs that have been analyzed in depth in the sports field are moods, highlighting how some dimensions could influence the performance of athletes [16,17]. One of the most commonly used questionnaires to analyze moods is the one proposed by McNair, Lorr and Dorppleman [18], called the Profile of Mood States (POMS), which considers seven factors: tension, depression, anger, vigor, fatigue, confusion and friendship.…”

Burnout in Elite Tennis Players of Different Junior Categories

“…The instrument is being used in recent studies in sports research. [20][21][22] The study used a version of the Athlete Burnout Questionnaire 3 . The questionnaire consists of 15 items that correspond to factors related to Burnout.…”

Sleep-Related Issues for Recovery and Performance in Athletes

“…2,3,12 Nevertheless, these findings are based on lab settings, where performance and physiological measures were analysed isolated from complex sport activities. Recent research underlines the importance of sleep for competition performance indicating there is a relationship between poor sleep quality and loss in a competition, 13 and between sleep duration and competition performance, 14 respectively. Accumulated evidence points at compromised sleep among the athletic population.…”
