Effects of Aerobic exercises on Sleep quality and Cardio-Respiratory endurance in healthy middle-aged adults- A Randomized Controlled Trial

Studies have shown that insufficient sleep is associated with hormonal changes in the body, including the release of leptin, ghrelin, cortisol, and growth hormone. Hormonal changes may result in reduced tissue insulin sensitivity. These changes have an impact on inappropriate food selection, changes in energy regulation, excessive food intake, and reduced physical activity. Studies on improving sleep quality through physical activity have mixed results. Significant amount of research has investigated the effects of physical activity on sleep. Results generally suggest that physical activity is beneficial for sleep, however it is unclear how large these benefits are. Research suggested that people who are physically active have better sleep quality than those who are not. Other studies found that moderate physical activity does not significantly improve sleep duration, habitual sleep efficiency or sleep disturbances.  The current study will examine whether physical activity has any effect on sleep quality and cardio-respiratory endurance
