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.
