The effect of exercise training on the quality of sleep in national-level adolescent finswimmers
Background: The purpose of the present study was to investigate whether the quality of sleep, in 91 national-level adolescent finswimmers, is affected by swimming style, swimming distance, and gender. Methods: Twenty-four hours before the opening of the National Championship, the participants recorded the training characteristics and answered the following two questionnaires: Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Score. Athletes were allocated to groups by gender, swimming style (monofin vs. bifin) and swimming distance (ā¤ 200 m vs. > 200 m). The dependencies between qualitative variables were estimated by chi-square test or Cramerās V test with modification by Fisherās exact test with cell frequencies less than 5. Binary logistic regression was used in the multi-factor model. Results: There was a difference in the variables of PSQI āusual getting up timeā and āhave pain during sleepā between the two swimming distance groups (ā¤ 200 m vs. > 200 m). By using a multi-factor model (Ļ2 = 13.541, p = 0.035), the variables of PSQI āusual getting up timeā and āhave pain during sleepā remained independent predictors of the swimming distance (p = 0.019, OR 1.75, 95% CI 1.09ā2.81). Conclusion: The athletes swimming distances > 200 m experience more episodes of pain during sleep and get up earlier than athletes swimming shorter distances. Ā© 2019, The Author(s)
