This survey used an online questionnaire addressing demographic and socioeconomic data, disease history, dietary characteristics, and questions regarding CrossFit. To assess intestinal health, the ROME IV Consensus Criteria and Bristol Scale were used. The Pittsburgh International Sleep Quality Index (PSQI-BR) and Epworth Sleepiness Scale were used to assess sleep quality.<\/jats:p><jats:p>\n          Results\u2003A total of 1,090 people (73.3% females) with a mean age of 31.2\u2009\u00b1\u20097.5 years were included. Considering the diagnosis of constipation, 36.9% of the patients were classified as constipated, especially females when compared with males (p\u2009&lt;\u20090.001). On the sleepiness scale, 22.4% of the volunteers showed excessive daytime sleepiness, which was also observed more frequently among females (p\u2009=\u20090.013). In the PSQI-BR, 47.4% of participants were classified as having poor sleep quality (poor sleepers). The overall PSQI-BR score was 5.81\u2009\u00b1\u20092.85, with no difference between males and females (p\u2009=\u20090.360). There was a positive correlation between the PSQI-BR global score and a diagnosis of constipation and excessive daytime sleepiness. There was a negative correlation between the stool type on the Bristol scale and the PSQI-BR global score.<\/jats:p><jats:p>\n          Conclusion\u2003The present study demonstrated that sleep quality was poor among CrossFit users, especially females, which can compromise their training performance.<\/jats:p>","DOI":"10.1055\/s-0043-1778014","type":"journal-article","created":{"date-parts":[[2024,2,15]],"date-time":"2024-02-15T23:57:20Z","timestamp":1708041440000},"page":"e16-e25","source":"Crossref","is-referenced-by-count":1,"title":["Sleep
