In the dynamic realm of sports science, the intricate interplay between various physiological and psychological factors significantly influences athletic performance. Among these factors, sleep quality and mental health, particularly depression, have garnered increasing attention due to their potential impact on athletic performance. In the context of football, a sport that demands both physical endurance and mental resilience, understanding the nexus between sleep, depression, and endurance performance becomes paramount.

Sleep plays a crucial role in the recovery and regeneration of the body, affecting various physiological and cognitive functions. Adequate sleep is not only essential for optimal physical performance but is also closely linked to mental health. On the other hand, depression, a prevalent mental health concern, can have profound effects on an athlete’s overall well-being, including sleep patterns and cognitive function.

Insufficient sleep and poor sleep quality are prevalent among athletes, potentially due to time demands, physical demands, and developmental needs. Sleep disturbances among athletes have adverse impacts on physical performance, mental performance, injury risk and recovery, medical health, and mental health. [1]

This research focuses on unravelling the intricate relationship between endurance performance and two critical factors: the quality of sleep and the presence of depression among football players. The endurance demands of football require players to operate at peak physical and mental capacities, making the exploration of these interconnected variables imperative for a comprehensive understanding of athletic performance
