This study investigates how short daytime naps affect physical performance and perceived exertion in competitive male soccer players. Using a repeated-measures crossover design, sixteen athletes from the U17 and U19 teams of Yeni Malatyaspor completed three experimental sessions separated by 48 hours. Each session involved one of three conditions: no nap (N0), a 25-minute nap (N25), or a 45-minute nap (N45). Participants' agility, repeated-sprint ability, and exertion levels were tested after each condition. Objective sleep data were collected with Fitbit Charge 6 devices, and subjective measures included the Hooper Index, Profile of Mood States, and sleep quality scales. The study aimed to determine whether strategic napping could acutely improve agility and reduce fatigue during anaerobic performance tasks in soccer players. It was hypothesized that longer naps would enhance agility and lower perceived exertion but would not significantly affect repeated-sprint performance.
