Maintenance of Healthy living is dependent to a large extent on leading an active life interspersed with moderate habits in eating and drinking. Since times immemorial, body beautiful has been admired and worshipped by all and great importance has been placed on the various methods of physical culture.
Exercise involves not only the energies of contraction and |

transformation of energy including mechanical efficiency of the body muscles but also acts in a way that power of body muscles increases and increased amounts of oxygen are made available.
Exercising is the key to dieting success since large amount of calories are burnt by exercise. Thus light exercise uses less and severe exercise more calories. The burning of more and more calories keeps the person active, his figure trim and prevents the development of those extra tyres round the waist or a paunch and a flabby body. The muscle increases in size chiefly through enlargement of smaller and less frequently excited fibers. There is increase in connective tissue and formation of more new blood channels so that the muscles become firm and even hard, thus their enduring power is increased. |

There are a number of studies which go to substantiate the fact that physical activity programmes executed regularly go a long way in maintaining good cardiac health. Similarly there is evidence based on animal experiments that exercise increases the formation and growth of new coronary channels in the heart. It cannot be denied that pleasurable physical activity not only gives a sense of well being, but also acts as an outlet for the pent up emotions, worries and tensions of daily life. In fact there is hardly any part of the body’s orchestra which does not benefit in one way or the other from exercise. It improves the adaptation of the organs to the various stresses and strains. Vigorous muscular contraction means more venous return of blood to the heart, better pulmonary ventilation and diffusion of gases in the lungs and so excretion of carbon dioxide. Thus, since there is improvement in respiratory and cardiac reserves of the body, it can stand the strain in better capacity. |
