With swimming, you can greatly strengthen the body.
Ancient Indian philosophers have identified 10 benefits of swimming that give a person clarity of mind, freshness, vivacity, health, strength, beauty, youth, purity, nice skin color and attention of beautiful women.
The main feature of this view is the finding in an aqueous medium in a relaxed state of anti-gravity (the density of water is almost 800 times the density of air) in a horizontal position.
Since water has a high thermal conductivity (30 times greater than air), it requires the body’s elevated cost of energy for even the loads of low intensity. So, stay in water at a temperature of 24-25 ° C for 3-4 min followed by a increase metabolism by 50-70%. The energy consumption when performing physical exercises in the water exceeds more than in 2 times, the energy consumption when performing the same exercises on the air. So swimming is the preferred means of recovery in people with overweight.
In swimming, the energy consumption depends on the speed and manner of navigation:
when swimming freestyle with a speed of 10 m/min the energy consumption is 3.6 kcal/min;
20 m/min and 5.1 kcal/min;
50 m/min is 12.2 kcal/min.
Less stress are the styles breaststroke and crawl on back, so they are recommended for people with lower functionality.
Health benefits of swimming
Swimming has a beneficial influence on functional systems of the body:
– strengthening respiratory muscles;
– increases mobility of joints of thorax;
– increases vital capacity and ventilation capacity of the lungs,
– significantly improved function of the respiratory system;
– reduced gravitational load on the spinal column;
– strengthens the muscles of the chest, which leads to improved posture;
– a positive effect of water environment on the nervous system is manifested in stimulating brain activity, accelerating the elimination of phenomena of fatigue during strenuous mental work, increase of mobility of nervous processes;
– hydro-massage helps the skin to improve regulation of the autonomic functions of the body, reflex stimulation of the cardiovascular system;
– improvement of peripheral circulation
– increases the body’s resistance to exposure to low temperatures.
