Silva, Andressa; Medicine & Science in Sports & Exercise: July 2020 - Volume 52 - Issue 7S - p 316
Sleep is a physiological process that plays a crucial role in human metabolic functions, being fundamental in muscle recovery.
PURPOSE: To associate sleep complaints with musculoskeletal injuries in adolescent track and field athletes.
METHODS: The sample consisted of 30 athletes, who are part of the athletics team of the Sports Training Center, aged between 13 and 22 years and average BMI of 21.21 ± 1.37 kg / m2. Participants completed the Sleep Complaints Questionnaire and retrospective data were collected on musculoskeletal injuries in the team's Physical Therapy sector (last six months). Spearman's correlation coefficient was used to obtain the association between the variables of the Sleep Complaints Questionnaire and the injuries. Finally, the linear regression model was used. The adopted significance level was α ≤ 5%.
RESULTS: The results showed that 23.3% of athletes reported having bad sleep, 40% reported good sleep and 36.7% reported very good sleep. The average total sleep time of participants was 07h22min ± 63.55 min (recommended 9 to 10h sleep for athletes) and the average severity of injuries was 1.47 ± 1.24 AU (1=no clearance and 5=severe or withdrawal over 28 days). Significant negative correlations were found between the variables sleep complaint and total sleep time (r=-0.438; p=0.016), sleep complaint and sleep quality (r=-0.472; p=0.009) and significant positive correlation between sleepwalking. and injury severity (r = 0.577; p=0.006). Linear regression data showed that sleep complaints influence 45% of total sleep time (R=0.456; β=-0.456; p=0.011); that sleep complaints have a 49% influence on sleep quality (R=0.494; β=-0.494; p=0.006); and that sleepwalking has a 64% influence on the severity of injury (R=0.646; β=0.646; p=0.002).
CONCLUSION: The presence of sleep complaints has negative implications on the duration and quality of sleep of the adolescent athlete, as well as increasing the severity of injury.
