Sleep quality assessment in Fitness Functional Athletes: A Cross-sectional Study

Introduction: Functional fitness is an intense sport that requires adequate recovery, with sleep playing a critical role in recovery. Factors such as training load and caffeine consumption may affect sleep quality, but few studies have examined these aspects simultaneously. Objective: To describe the quality and quantity of sleep in Fitness Functional athletes, considering training load and caffeine consumption. Method: Cross-sectional and descriptive study of male functional fitness athletes (18 to 35 years old). Sociodemographic data, sleep quality (Pittsburgh Sleep Quality Index - PSQI), training load and food consumption patterns were collected during the transmutation phase using an online form. Results: Of the 20 included athletes, 85% reported good or very good subjective sleep quality, but 90% had poor sleep quality according to the total PSQI score. In addition, 30% of participants reported sleeping less than 7 hours per night and low consumption of caffeinated beverages and energy supplements. Conclusion: Although athletes reported good subjective sleep quality, the objective assessment (PSQI) showed poor quality that was not related to caffeine or supplement consumption. The high energy demands of sport may negatively affect sleep, with resting times below international recommendations.

引言：功能健身是一项高强度运动，它要求充分的恢复，其中睡眠在恢复过程中扮演着至关重要的角色。诸如训练负荷和咖啡因摄入等因素可能会影响睡眠质量，但很少有研究同时考察这些方面。研究目的：旨在描述功能健身运动员的睡眠质量与数量，并考虑训练负荷和咖啡因摄入。研究方法：对18至35岁的男性功能健身运动员进行横断面和描述性研究。在转换阶段，通过在线表格收集了社会学人口数据、睡眠质量（匹兹堡睡眠质量指数 - PSQI）、训练负荷和食物消费模式。研究结果：在20名受试运动员中，85%报告了良好的或非常好的主观睡眠质量，但根据PSQI总分，90%的运动员睡眠质量较差。此外，30%的参与者报告每晚睡眠时间少于7小时，并且咖啡因饮料和能量补充剂的摄入量较低。结论：尽管运动员报告了良好的主观睡眠质量，但客观评估（PSQI）显示的睡眠质量较差，这与咖啡因或补充剂的摄入无关。体育运动的能量需求可能对睡眠产生负面影响，休息时间低于国际推荐标准。
