In general, a human goes through different periods during his life, from infancy to old age, and each of these stages is faced with its own biological and physiological changes. According to the report presented by the World Health Organization, the last period of human life or old age begins when the person reaches the age of 60, and in this period, the biological and physiological characteristics of a person change in a way that causes the deterioration of the physical and mental abilities of a person. One of the most important mental disorders of a human being is dementia. This disability and chronic disorder, which sometimes leads to acute mental problems, is associated with personality change, situational awareness, and impaired memory, judgment, and thinking. This disability in its most common type will lead to Alzheimer's disease.
Research shows that if effective treatments for the treatment and prevention of Alzheimer's are not known, the number of people suffering from this disease will reach one hundred million people by the year 2343. Since no effective drug treatment for this disease has been proven, various scientists decided to Use other treatment methods that can control the ways of causing the disease to prevent and control this disease. One of the suggested approaches to achieve this goal is the use of different sports activities. Different studies show that the risk of dementia is reduced in the elderly who have a higher level of physical activity. In fact, sports and physical activities lead to maintaining body function and health. Physiologically, and as a result, it is very effective in maintaining brain health and cognitive function in the elderly. In this review article,, the role of maintaining muscle mass in the prevention of Alzheimer's and types of physical activities in terms of intensity, duration and type of activity in controlling and improving the conditions of patients is addressed.
