the scientific way of keeping good health of the body!

hai friends...how are we?

Scientists have studied the movements of various parts of the body and have identified those which produce positive effect for the good health…and they have grouped them into five categories depending upon which part of the body gets the positive benefits…

So, if we do only one of them then only one part of the body gets exercised properly and others moderately or less.

This shows that we should not just do ‘only one exercise and should have a regimen comprising of all five or more than one or with few of them more and others less’…depending upon our need…some need more cardiac work up…some who want to reduce weight should take up more of walk…and so on.

These five are as follows:-

1.Isometric exercise….this is performed by contracting muscles against an immovable object. Eventhough the body does not move, muscles push hard against each other or against an immovable object and thus gain strength. This type can improve muscle strength which can be especially important for older people in preserving independent living.

 

2.Isotonic exercise….This requires contraction of muscles and the movement of joints. Weight lifting and many other forms of calisthenics (bending, jumping and stretching exercises) fit into this category. It can improve muscle strength and muscle endurance, if it is sufficiently lengthy. It is more helpful in improving appearance than health.

3.Isokinetic exercise….Exertion is required for lifting and additional effort is required to return to the starting position. This type of exercise requires specialized equipment that adjusts the amount of resistance according to the amount of force applied. It is superior than isometric and isotonic exercises in improving muscle strength and muscle endurance. It is inconvenient for many people and requires expensive and elaborate equipment. Its most important use is in physical rehabilitation.

 

4.Anaerobic exercise….It includes short distance running, some calisthenics, soft ball and other exercises that require short, intensive bursts of energy but do not require an increased, amount of oxygen use. Such short, strenuous exercises improve speed and endurance, but they may be dangerous for people with coronary heart disease.

5.Aerobic exercise….is any exercise that requires dramatically increased oxygen consumption over an extended period of time. The most common forms of aerobic exercise are jogging, walking, dancing, swimming, cycling etc.

 

Among all these exercises Aerobic Exercise is found by health psychologists as a sustained exercise that stimulates heart and lungs improving the body’s utilization of oxygen. Other exercises have less effect on overall fitness because they draw on short term stores of glycogen rather than on the long-term energy conservation system.

So, those who want to reduce the weight or obesity should do more of aerobic exercises so that the fat stored is burnt…when we run the body needs instant energy…but melting of fat and converting it into energy takes time…so, body uses the energy that is waiting in the ready use store…i.e the energy made out of the previous meal…once you run, this gets used and ready use store gets empty…so we feel very hungry…we end up in hogging…this gets converted to energy and gets burnt when we run next time…so, the fat never gets melted. So, running is not a good intervention to reduce fat.

 

keep rocking guys and gals...
