Describe the benefits of physical activity in the elderly
Compared with those who are inactive, older adults who are active weigh less; have greater flexibility, more endurance, better balance, and better health; and they live longer. Physical activity also increases blood flow to the brain, thereby preserving mental ability, alleviating depression, supporting independence, and improving quality of life. Regular physical activity tones, firms, and strengthens muscles, helping to improve balance, restore confidence, reduce the risk of falling, and lessen the risk of injury should a fall occur.?
