India is home to more than 1 billion people, with 16 percent of the world's
population on 2.4 percent of the globe's land area. While global population has
increased threefold during this century, from 2 billion to 6 billion, the population
of India has increased nearly five times from 238 million to 1 billion in the same
period. India thus faces the most critical question of improving health levels of its
population despite the constraints of persisting mass poverty.
Physical activity or exercise is a cornerstone of a healthy life style. The
human body is designed for physical activity and movement. Not only does
physical activity make the individual look and feel better, but it is also critical for
improving health and extending the life. Throughout his life, man has to be
physically active in order to procure his daily food and to succeed in the battle for
survival. The marked deterioration in health and physical automation has
mechanized our day-to-day life. Now-a-days people become almost sedentary and
physically inactive because of very limited movement caused by scientific
innovation. Physical inactivity can have serious implications for people health,
observes the World Health Organization.
