Produção científica na língua portuguesa sobre o sono em atletas: uma revisão sistemática

Abstract

Sleep is a physiological state with a temporary suspension of perceptual activity, with phases and stages, which alternate during the process when we are sleeping. In moments of sleep deprivation, we are faced with an imbalance of the circadian rhythmicity causing changes in the metabolism, production of hormones and muscle repair. The objective of this review study is to analyze the scientific production in the Portuguese language about the sleep in athletes. The method used was a systematic review of studies published in the last 18 years in the databases Scielo, Web of Science, Scopus, and Sportdiscus. In the findings, eight Portuguese studies were selected, in which they investigated sleep quality, sleepiness, chronotype and quality of life. All studies have demonstrated the importance of quality sleep for athletes in training periods and competitions for a physical, cognitive recovery. The disclosure of these studies may develop and disseminate to coaches and athletes evidence-based information about the importance of sleep in the sports training.
