What are the benefits of swimming for men?

　　Benefits of swimming:

　　1. The resistance of water - the resistance of people's activities in water is 800 times that of air. If the movement speed is the same, to complete the same set of movements, you will need to use at least 6 times more force in the water than on land. Then, water sports will achieve twice the result with half the effort.

　　2. The heat dissipation power of water - The heat dissipation power of water is much greater than that of air, more than 28 times that of air. Experiments have shown that the amount of calories a person consumes by exercising in the water for twenty minutes is equivalent to more than an hour of exercising on land with the same intensity.

　　3. The buoyancy of water - The buoyancy of water allows obese people to feel relaxed and comfortable when moving in the water, overcoming the shortcomings of fatigue on land. It can be said that water exercise is the most suitable physical activity for obese people.

　　4. Massage and skin care properties - Since exercise in water causes less sweating, the effect of salt in sweat after training on land is reduced. skin stimulation. The friction and beating of water flow and waves have a special massage effect, which can effectively avoid and reduce skin relaxation and aging, making the skin smooth, smooth and elastic. At the same time, it can also eliminate depression and fatigue, and reduce mental and physical burdens.

　　5. Weight Loss - Water aerobics uses aerobic energy consumption and mainly uses glycogen and fat. Therefore, when performing this exercise together with a scientific nutritional diet plan, it has a very significant effect on regulating body fat metabolism and reducing body fat.

　　6. Weight gain - Compared with lean people, exercising in water and following a scientific diet can moderately increase subcutaneous fat and muscle. Due to the heat dissipation stimulation of the body surface and the buoyancy pressure stimulation, the body fat distribution is adjusted reflexively, causing it to transfer to the subcutaneous layer, promoting fat synthesis, forming a very thin fat layer, and making the body lines flexible and harmonious.

　　Due to the various characteristics of water, the body has the strongest plasticity when exercising in water, especially the training effect on the legs, waist and abdominal muscles is more obvious, so the muscles in the water exercise Isometric exercise is regarded as the most popular muscle training method today.

　　Things to note when swimming

　　Physical examination

　　Because when swimming, people consume up to eight times more physical energy than usual. Therefore, people with heart disease, active tuberculosis, liver disease, and kidney disease should not participate in swimming. suffer from pink eye People with infectious skin diseases should not swim to avoid infecting each other.

　　Warm up exercise

　　Make preparations on the shore before entering the water. Otherwise, sudden strenuous activities may easily cause muscle injuries or other accidents. You can use limb movements such as raising your legs high, squatting and standing up.
