Types of physical activity:

There are two types of exercise: isotonic and isometric.

* Isotonic exercise involves the contraction of muscle groups against a low resistance over a long run, such as running, swimming or calisthenics. Isotonic exercise is more beneficial for the cardiovascular system: increasing the amount of blood pumped by the heart and promotes the proliferation of small vessels that carry oxygen to the muscles, these changes allow for sustained physical activity. An example of this type of exercise is aerobics exercise system designed to improve cardiovascular conditions. A regular program of aerobic can improve the body’s ability to absorb oxygen efficiently, increasing the force and increases

resistance. For maximum performance, the exercises

Aerobic should be three to five times a week,

minimum period of 15 minutes to an hour.

* Isometric exercise muscles move against high resistance along a short route, as the push or pull an immovable object. Isometric exercise is best for developing large muscles, increases the thickness of the muscle fibers and their ability to store glycogen, the fuel of muscle cells. This type of exercise is designed to increase muscle strength, an example of this is the work done with machines and weightlifting.

* A cardiac level, there was an increase of the organic resistance, improved circulation, regulating pulse and decreased arterial pressure.

* In the lungs, improvement is seen in lung and subsequent oxygenation.

* Development of muscle strength, which in turn determines an increase in bone strength (increased bone-mineral density) thus prevents osteoporosis.

* Improved body position by strengthening the lumbar muscles.
