EFFECTS OF HIGH INTENSITY EXERCISE - CROSSFIT® AND BODYBUILDING ON SLEEP OUTCOMES (DAYTIME SLEEPNESS AND INSOMNIA), CHRONOTYPE AND SEVERITY OF DEPRESSION

Introdução

Evidences show that physical activity is an important factor for maintaining health, delaying the loss of functional capacity throughout life (CIPRIANI et al., 2010; MACEDO et al., 2003); exerts a beneficial function on mood and sleep alterations, being a method of prevention and treatment without medication (ZUO et al., 2012; JIMÉNEZ-GARCÍA et al., 2021). This research is justified, given the importance of the findings to know how the professional performance should be guided aiming at a benefit for the health and performance of practitioners.

Objetivo

To assess the effects of CrossFit® and bodybuilding on sleep outcomes (daytime sleepiness and insomnia), chronotype, and depression.

Métodos

Descriptive analysis with a quali-quantitative approach emphasizing the sociodemographic, anthropometric and sleep outcomes of a group of Crossfit® practitioners and a group of Bodybuilding practitioners, both in the city of Fortaleza/CE, Brazil during the period from February/2022 to May/2022. Data were collected through a structured questionnaire comprising a sociodemographic assessment form and some instruments: ESS, MEQ, IGI and PHQ-9.

Resultados

90 CrossFit group participants answered the questionnaires, 38 men and 52 women. The mean total age was 33.6. In the BodyBuilding group, 44 individuals participated, 21 men and 23 women. The mean age was 32.6. As for the classification of EDS using the Epworth scale, in the CrossFit group, 30% have EDS and in the Bodybuilding group, 18.2%. As for the chronotype (MEQ), in the CrossFit group, 53.3% were morning, 41.1% indifferent and 5.6 were afternoon. In the Bodybuilding group, 47.7% were morning, 40.9% indifferent and 11.4% were in the afternoon. The Mann-Whitney U test, when comparing the IGI between the chronotypes, showed that in both groups, individuals with evening preferences tend to have higher levels of insomnia severity. When comparing depression rates (Mann-Whitney U test) between chronotypes in the CrossFit group, afternoons have higher rates of depression than mornings. In the Bodybuilding group, no difference could be found. In the correlation of variables test (Spearman's rho) in both groups, higher depression indices are associated with higher values ​​of insomnia severity indices.

Conclusões

The result will reflect in the academic and professional spheres, where the result of CrossFit® in the health and life of its practitioners will allow a better understanding of this method.
