There are infinite benefits for men to do it in the water

Swimming is a very popular sport, especially in the hot summer, when many people swim. So what are the precautions for swimming? What are the benefits of swimming?

Benefits of swimming:

1. Water resistance - The resistance felt by people in water is 800 times greater than in air. If the speed of movement is the same, the same set of movements requires at least 6 times more strength in water than on land. Therefore, water sports will achieve twice the result with half the effort.

2. Water's heat dissipation ability - Water's heat dissipation ability is much greater than air, more than 28 times that of air. Experiments have shown that the amount of heat consumed by a person exercising in water for 20 minutes is equivalent to more than an hour of exercise on land at the same intensity.

3. The buoyancy of water - The buoyancy of water allows obese people to feel relaxed and comfortable when exercising in water, overcoming the shortcoming of easy fatigue caused by land activities. It can be said that water sports are the most suitable sports activity for obese people.

4. Massage and skin care - Since water sports cause relatively less sweating, the salt in the sweat after land training can reduce the stimulation to the skin. The friction and beating of water flow and waves have a special massage effect, which effectively avoids and reduces the relaxation and aging of the skin, making the skin smooth, smooth and elastic. At the same time, it can also eliminate depression and fatigue, and reduce the mental and physical burden.

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

6. Weight gain - Compared to thin people, water exercise combined with a scientific diet can increase subcutaneous fat and muscle to a certain extent. Due to the stimulation of body surface heat dissipation and buoyancy pressure, the distribution of body fat is reflexively adjusted, transferred to the subcutaneous tissue, promoting fat synthesis, forming a very thin fat layer, and making the body lines soft and harmonious.

Due to the various properties of water, the body's plasticity is strongest when exercising in water, especially the training effect on the leg and waist and abdominal muscles is more obvious, so muscle training in water is regarded as the most popular muscle training method today - isokinetic exercise.

Swimming Tips

Physical examination

Because when swimming, people consume eight times more energy than usual, so people with heart disease, active pulmonary tuberculosis, liver disease, and kidney disease should not swim. People with conjunctivitis and infectious skin diseases should also not swim to avoid mutual infection.

Warm-up exercises

Before entering the water, you should do some warm-up exercises on the shore. Otherwise, if you suddenly engage in more intense activities, it is easy to cause muscle injuries or other accidents. You can use limb exercises such as high leg raises, squatting and standing up.
