Abstract text INTRODUCTION:
Sleep quality is an important factor which deserves to be taken into account in evaluations of high-performance athletes (Silva et al., 2012). Thus, the objective of this study was to investigate the sleep complaints, patterns and disorders of elite athletes during preparation for the Rio 2016 Olympic Games.
METHODS:
The study included 146 athletes from the Brazilian Olympic Team (male: n = 86; 59%; female: n = 60; 41%) with a mean age of 24.3 ± 4.6 years. The athletes underwent a single polysomnography (PSG) evaluation at the Sleep Institute, São Paulo, during a week in which the athletes were undergoing clinical evaluations. Sleep specialists evaluated the athletes and asked about their sleep complaints during a clinical consultation. In this evaluation week, the athletes did not take part in any training or competitions.
RESULTS:
53% of the athletes reported a sleep problem during the medical consultation, the most prevalent being insufficient sleep/waking up tired (32%), followed by snoring (21%) and insomnia (19.2%). The sleep efficiency and sleep stages revealed that men had a lower percentage of sleep efficiency and slow wave sleep than the women (p=0.001 and p=0.05, respectively). The PSG examination and clinical evaluation, we found insomnia to be the most prevalent sleep disorder among the athletes (19%), followed by bruxism (7%) and sleep apnea (7%) (apnea/hypopnea index [AHI] > 5 events/hour).
CONCLUSION:
The fact that we found sleep complaints in 53% of the athletes is in line with the findings in the literature, which show a similar percentage of sleep complaints such as snoring, insomnia, insufficient sleep and bruxism in the general population.
