Answer:
On the ageing process, physical activity can play very effective role, however, it should be implemented in a suitable manner. It is a well-known fact that regular physical activity is the supplement to delay the ageing process. It can in some cases, overturn the most common signs of ageing viz., loss of muscles and bones, increased body fats, decline of memory, decreased metabolism, flexibility and blood flow etc. Participation in physical activity for a longer duration maintain functional fitness among aged population in following manner: (i) Reduces loss of muscles mass: With advancing age the muscle mass decreases. The accumulation of fats reduces due to regular exercise. Ageing has a depressing consequence on metabolism. Regular physical activity results in dropping the metabolic rate and decreases the loss of lean body mass. (ii) Maintains bone density: With advancement of age, bone density decreases as well generally leading to the rupture or osteoporosis. Physical activity assist in minting bone mass and prevent osteoporosis. Bone growth gets stimulated with resistance exercises. (iii) Improves lungs capacity: Oxygen uptake and exchange increases and enhances the lungs capacity due to regular exercise. In maintenance of strong lungs, it plays prominent role and reduces the loss of elasticity of the lungs and chest wall. (iv) Lessens stress and tension: Regular physical activity has a distinctive capability to slow down the depression process by reducing stress and tension.
