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.
There is a positive relationship between mood states and mental health. The aim of the present study was to investigate the construct validity and internal consistency of the Brunel Mood Scale (BRUMS) for use with different populations, which are physically active and apparently healthy. Measures were obtained from 1295 male (N = 709, 34 ± 20 years, mean ± SD) and female (N = 576, 43 ± 24 years, mean ± SD) volunteers. Factor analysis was used, verifying that six factors (components) accounted for 62.65% of the total variance of the scale. The Varimax method with Kaiser Normalization for the rotation of the factors for the main components, and it was observed that the 24 scale items loaded on six mood factors (anger, depression, tension, vigor, fatigue, and confusion). Internal consistency was good for all the factors identified. We suggest that the results provide some support for validity of the BRUMS for use with different populations, which are physically active and apparently healthy.

Resumo: O objetivo do presente artigo é investigar na literatura os principais motivos de aderência e desistência de brasileiros praticantes de exercícios físicos em academias de ginástica. Trata-se de um estudo de revisão de literatura com caráter qualitativo. Utilizou-se os descritores em ciências da saúde considerados relevantes para busca de estudos empíricos nas bases de dados disponíveis no portal de Periódicos da Capes. Dentre os motivos mencionados para a aderência, destacam-se a busca pela saúde, estética, socialização, melhoria da condição física e bem-estar. A desistência das academias de ginástica pelos praticantes de exercícios físicos foi atribuída à falta de tempo, preguiça, distância que o praticante deverá percorrer do seu trabalho ou da sua casa até a academia e ao alto custo das mensalidades. A identificação e administração destes fatores devem ser consideradas na promoção da atividade física e saúde. Palavras-chave: Aderência. Academias de Ginástica. Motivação. Exercício Físico.
Adherence at physical exercises in fitness centersAbstract: The aim of this study is to investigate the reasons in the literature of adhesion and dropout of practitioners of physical exercises in fitness centers. This is a study of literature review with qualitative aspect. Using the descriptors in the health sciences to search for empirical studies in the databases available on the portal's regular Capes. Among the reasons mentioned for adhesion, it is the search for health, beauty, socialization, improving the physical condition and well-being. The dropout of fitness centers by practitioners of physical exercises has been attributed to lack of time, laziness, distance that the practitioner should go to their work or their home to the academy and the expensive price expend monthly. The identification and management of these factors should be considered in the promotion of physical activity and health.
Brandt, R, Bevilacqua, GG, Coimbra, DR, Pombo, LC, Miarka, B, and Lane, AM. Body weight and mood state modifications in mixed martial arts: An exploratory pilot. J Strength Cond Res 32(9): 2548-2554, 2018-Mixed martial arts (MMA) fighters typically use rapid weight loss (RWL) as a strategy to make competition weight. The aim of the present study was to compare body weight and mood changes in professional male MMA athletes who used strategies to rapidly lose weight (n = 9) and with MMA athletes who did not (n = 3). Body mass and mood states of anger, confusion, depression, fatigue, tension, and vigor and total mood disturbance were assessed (a) 30 days before competition, (b) at the official weigh-in 1 day before competition, (c) 10 minutes before competition, and (d) 10 minutes postcompetition. Results indicated that RWL associated with reporting higher confusion and greater total mood disturbance at each assessment point. Rapid weight loss also associated with high anger at the official weigh-in. However, in performance, RWL did not have deleterious effects on performance. The RWL group also reported greater total mood disturbance at all assessment points with a moderate difference effect size. Research supports the notion that RWL associates with potentially dysfunctional mood states.
Resumo: O objetivo da presente pesquisa foi avaliar os estados de humor de velejadores após regatas do Pré-Panamericana de Vela, bem como fatores associados. A amostra foi composta por 18 atletas de ambos os sexos, que foram avaliados por meio da Escala de Humor de Brunel. Os atletas apresentaram elevada tensão e fadiga, associadas a altos níveis de vigor. Homens apresentaram maior vigor e fadiga, e menor tensão, depressão e raiva do que as mulheres, porém sem diferenças estatísticamente significativas. Quanto à classe, velejadores de classes individuais apresentaram maior tensão, depressão e confusão do que os de classes com dois tripulantes, porém sem diferenças estatísticamente significativas. Os estados de humor apresentados pelos atletas após regatas do Pré-Panamericano de Vela podem ser considerados diferente do ideal para o rendimento esportivo, porém ainda existe pouco domínio teórico dos estados de humor de velejadores para análises mais aprofundadas.
