Aged Population is an emerging global public health concern. The ability to control balance with age is disturbed as a result of the decline in vestibular, vision, somatosensory, musculoskeletal and central nervous systems. In addition, many older adults with balance disorders suffer from orthopedic limitations and cognitive impairment. Balance performance in the elderly is a critical aspect of functional ability and overall health. Thus, falling and fear of falling related to balance disorders is a significant concern and a common risk factor among the elderly population. Is. Understanding and addressing balance function in the elderly is very important to increase their quality of life and reduce the risk of falls. Physical activity plays an important role in increasing balance function and reducing disability in late life. Participating in regular physical activity, including strength training, endurance training, and activities focused on balance and mobility, can significantly improve motor skills, coordination, and agility. Studies show that strength training programs can increase balance, reduce the risk of falls, and improve functional outcomes in older adults. In addition, physical activity is positively associated with better performance in balance tests, as one extra minute of physical activity leads to a 4% improvement in balance over one week and a 5% cumulative improvement over two years. Therefore, promoting physical activity tailored to the needs of older adults is necessary to maintain physical condition, prevent falls, and maintain independence in late life. The purpose of this study is to investigate the effect of physical activity on balance and functional disorders in the elderly with a review approach.
