Based on the relationship between sleep and sports performance, the present study aimed to evaluate sleep quality and excessive daytime sleepiness among adult CrossFit (CrossFit, LLC, Santa Cruz, CA, USA) practitioners and to verify possible associations with intestinal health. This cross-sectional study involved males and females aged ≥ 18 years who had been regularly practicing CrossFit for at least 3 months. 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. A total of 1,090 people (73.3% females) with a mean age of 31.2 ± 7.5 years were included. Considering the diagnosis of constipation, 36.9% of the patients were classified as constipated, especially females when compared with males ( < 0.001). On the sleepiness scale, 22.4% of the volunteers showed excessive daytime sleepiness, which was also observed more frequently among females ( = 0.013). 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 ± 2.85, with no difference between males and females ( = 0.360). 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. The present study demonstrated that sleep quality was poor among CrossFit users, especially females, which can compromise their training performance.
基于睡眠与运动表现之间的关系，本研究旨在评估成年CrossFit（美国加利福尼亚州圣克鲁斯市CrossFit有限责任公司）练习者的睡眠质量和日间过度嗜睡情况，并验证其与肠道健康的可能关联。 这项横断面研究纳入了年龄≥18岁、定期进行CrossFit练习至少3个月的男性和女性。该调查使用了一份在线问卷，涉及人口统计学和社会经济数据、疾病史、饮食特征以及有关CrossFit的问题。为评估肠道健康，采用了罗马IV共识标准和布里斯托量表。使用匹兹堡国际睡眠质量指数（PSQI-BR）和爱泼华嗜睡量表来评估睡眠质量。 总共纳入了1090人（73.3%为女性），平均年龄为31.2±7.5岁。考虑到便秘的诊断，36.9%的患者被归类为便秘，尤其是女性与男性相比（<0.001）。在嗜睡量表上，22.4%的志愿者表现出日间过度嗜睡，在女性中也更频繁地观察到（=0.013）。在PSQI-BR中，47.4%的参与者被归类为睡眠质量差（睡眠不佳者）。PSQI-BR的总体得分是5.81±2.85，男性和女性之间没有差异（=0.360）。PSQI-BR全球得分与便秘诊断和日间过度嗜睡之间存在正相关。布里斯托量表上的粪便类型与PSQI-BR全球得分之间存在负相关。 本研究表明，CrossFit使用者的睡眠质量较差，尤其是女性，这可能会影响她们的训练表现。
