The aging population is a growing demographic worldwide, and promoting the health and well -being of elderly individuals is becoming increasingly important. Physical activity has been shown to have numerous health benefits, but the most eefctive approach for promoting physical activity in elderly individuals remains unclear. This study aimed to compare the impact of supervised physical activity versus self -managed physical activity on the quality of life of elderly individuals. A clinical trial was conducted at Badar Medical Complex, University Teaching Hospital and Avicenna Hospital. 52 parctiipants were recruited, with 26 i n each group. The supervised physical activity group parctiipated in a structured physical acvtiity program, while the self-managed group received educational materials and were encouraged to engage in physical activity on their own. The SF -36 quesotinnair e was used to assess quality of life, and demographic information was also collected. Results: The results showed that people in the supervised physical activity group did much better on the SF-36 than those in the self-managed physical activity group, except for the body pain and general health domains. In particular, the group that was watched over did much better in the areas of physical functioning, rolephysical, vitality, social functioning, and mental health. Conclusion: The findings suggested that supervised physical activityprograms may be more effective in improving the quality of life in elderly individuals, particularly in the domains of physical function, social interactions, energy levels, and mental health. These findingshighlight the importance of structured and supervised physical activity programs for promoting health and well-being in elderly individuals.
