In this kind of cyclical exercise also involves all muscle groups, but because of the horizontal position of the body and the specifics of the aqueous medium load on the circulatory system in swimming less than running or walking on skis.Several smaller and power consumption, thereby to achieve the desired effect of improving swimming training necessary to develop a sufficiently high rate at which the heart rate zone would reach coaching mode (not less than 130 beats / min).Without mastering the proper technique of navigation make it quite difficult.As a result, difficulty inhaling (water pressure on the chest) and expiratory swimming contributes to the development apparatus of external respiration and increases lung capacity.

Specifics conditions for swimming (humidity, microclimate pool) is particularly beneficial for people with asthma.When sailing asthma attacks usually do not occur, whereas when running during forced breathing their probability is higher.The virtual absence of stress on the joints

and spine can successfully use this type of muscular activity in spinal diseases (deformation, discogenic sciatica, and so on. N.).

Energy supply of muscle activity during swimming has a number of features.The very stay in water (without performing any movements) causes an increase in power consumption by 50% (compared with their levels), maintaining the body in water require increased energy consumption in the 2-3, since the thermal conductivity of water 25 timesgreater than air.Due to the high water resistance at a distance of 1 m spent swimming in 4 times more energy than when walking with the same speed, i.e.about 3 kcal / kg per 1 km (walking - 0.7 kcal / kg / km) and therefore swimming can be a great means of normalization of body weight - provided load regularity (at least 30 minutes 3 times a week).With the mastery of technique of swimming, sufficiently intense and prolonged load swimming can be effectively used to improve the functional state of the cardiovascular system and reduce coronary heart disease risk factors.
