Explain Modulating Process of Ageing
Despite various researches, ageing becomes an inevitable process. The only option is to have good control measures. These are highlighted herewith:
a) Nutrition: Caloric restriction retards ageing. Isn't that interesting? This is due to decrease in O2 consumption, decrease in free radicals and a decrease in peroxidation.
b) Exercise: Regular exercises increase O2 uptake capacity. It improves cardiac performance and reduces muscular-skeletal disabilities. Age-related 'Resting Metabolic Rate' (RMR) gets reduced in exercising individuals and helps to increase antioxidant reactions.
