rhythmic movements of swimming are shown demanding not only with the heart and lungs, which helps develop resistance, but also with virtually all major muscle groups of the body. While developing strength and muscular endurance, swimming places less stress on tendons, ligaments and joints of the body than running and other endurance activities.
The power of swimming as aerobic conditioning both beginner and advanced level has been well established. In one study, a group of teenage girls who started a swimming program increased their VO2max average 14 percent in just seven weeks. Among athletes, the value of VO2max using the main swimming is almost on par with that of runners and skiers, and is slightly higher than cyclists.
In addition to their training, swimming superbly placed as the muscles of the upper body, something that can not get run. Since leg muscles are used primarily to maintain a level body in the water, not to drive, the more trust a swimmer in his arms, move more efficiently in water. In fact, studies show that among competitive swimmers, about 80 percent of forward motion comes from the arms and shoulders. Swimming is particularly effective for building muscle pecs and abs. And because of breath control, placed in conditions of respiratory muscles and improves the forced vital capacity, a measure of breathing capacity.
The low rate of injury among swimmers is due to the natural buoyancy of water, which supports the body and relieve the stresses of weight. Since swimming does not place any load on the spine, hips, knees and other joints, is especially beneficial for people with overweight and having problems with your knees or lower back. Due to the low voltage, those people can exercise longer and swam vigorously when perform virtually any other type of exercise. Swimming is particularly effective to maintain and improve aerobic capacity of injured runners and other athletes who otherwise could not keep exercising.
