The role of sleep can be described as regaining the energy of the body to recover the body after exercise or any other exhaustive routine. The body acts in such a way during sleep that it normalizes all the functions of the body to the required standard and condition in the body.  For example, because of extensive exercises, there may be any anomaly in breathing rate, but with proper sleep, the normal functioning of the lungs can be regained in athletes. At the same time, physical exercises may result in stress and anxiety, but proper sleep time may help to reduce these aspects also. The blood circulatory system may also be affected by intense exercises. Sleep quality helps bring the circulatory system of athletes to normal condition. The research was based on primary data analysis to determine the research used SPSS software, which included descriptive statistics and paired sample correlations that also explain the graphical analysis between them. In short, we can say that all athletes' Physical recovery depends on proper rest and improved sleep quality. This is one of the foremost benefits of the quality of sleep, as it helps improve athletes' physical health as well. The other important implication of the role of sleep quality in athletic performance and recovery is the aspect of muscle function related to it. Various and consistent physical exercises for the training of athletes may cause muscle fatigue. This is because of the activity of anaerobic respiration in muscles due to less oxygen concentration in the body. As a result of anaerobic respiration, the amount of lactic acid produced in muscles increases, and this overproduction of lactic acid can cause muscle fatigue. However, the aspect of muscle fatigue can easily be reduced by proper sleep quality because, during sleep duration, the extra amount of lactic acid is converted into glucose, reducing muscle fatigue.
