Swimming is a familiar sport and a very popular one. Even people who don't like sports, there are many people who like to go to the water to play. Swimming to lose weight can help us burn a lot of calories, and it can also allow us to increase muscles while doing aerobic exercise. Swimming to lose weight can make us have streamlined muscles, very beautiful.

The benefits of swimming

Swimming Benefit 1: Enhance myocardial function

When people exercise in water, all organs are involved, consume more energy, accelerate blood circulation, and provide more nutrition for the organs in motion. The increased blood flow rate will increase the load on the heart, making it beat faster and contract stronger and stronger. People who swim regularly have very good heart function. The average human heart rate is 70-80 beats per minute, and the stroke volume is 60-80 ml. Regular swimmers have a heart rate of 50-55 beats/min, and many excellent swimmers have a heart rate of 38-46 beats/min and stroke volumes as high as 90-120 ml. The action of water during swimming makes it easy for the blood from the extremities to return to the heart, which increases the heart rate. Long-term swimming will significantly increase cardiac motion, strong contractility, thickening of blood vessel walls, increased elasticity, and increased stroke volume. Therefore, swimming can exercise a strong heart.

Swimming Benefit 2: Enhanced resistance

The water temperature in the swimming pool is usually between 26 and 28 degrees. Immersion in water quickly dissipates heat and consumes a lot of energy. In order to replenish the heat emitted by the body as soon as possible, meet the needs of the balance of cold and heat, make the nervous system respond quickly, speed up the body's metabolism, enhance the body's ability to adapt to the outside world, and resist the cold. People who often participate in winter swimming, due to the improvement of body temperature regulation function, the chance of catching a cold is relatively small, and it can also improve the endocrine function of the human body, that is, the increase of the function of the pituitary gland, thereby improving the resistance and immunity to diseases.

Swimming Benefit 3: Bodybuilding

When swimming, people usually use the buoyancy of water to lie prone or supine in the water, relax and stretch the whole body, so that the body can develop comprehensively, symmetrically and harmoniously, and the muscle lines are smooth. Exercise in the water reduces the impact of the ground on the bones, reduces the probability of bone aging, and makes bones and joints less prone to deformation. The resistance of water can increase the intensity of exercise, but this intensity is different from equipment training on land. The muscles of the body can make the lines of the whole body smooth and graceful.

Swimming Benefit 4: Strengthening lung function

Breathing mainly depends on the lungs, and the strength of the lungs depends on the strength of the respiratory muscles. Exercise is one of the effective means to improve and increase lung capacity. According to the actual measurement: when swimming, a person's chest is subjected to a pressure of 12-15 kg. The cold water stimulates muscle contraction, making it difficult to breathe, forcing people to breathe hard, increasing the depth of breathing, and making the amount of oxygen inhaled to meet the needs of the body. The vital capacity of an ordinary person is about 3200 ml, the difference in breathing (the difference between the expansion and contraction of the chest circumference during maximal inhalation and maximal exhalation) is only 4-8 cm, and the maximum oxygen intake during vigorous exercise is 2.5-3 liters/min . It is 10 times larger than that at rest; the vital capacity of swimmers can be as high as 4000-7000 ml, the breathing difference can reach 12-15 cm, and the maximum oxygen uptake during vigorous exercise is 4.5-7.5 L/min, which is 20 times higher than that at rest. Swimming promotes the development of respiratory muscles, increases the chest circumference, increases the vital capacity, the alveoli are more open during inhalation, and the ventilation is smooth, which is extremely beneficial to health.

Swimming Benefit 5: Skin care

When people swim, the water washes the skin, sweat glands and fat glands, which plays a good massage effect, promotes blood circulation, and makes the skin smooth and elastic. In addition, when exercising in water, the salt in sweat is greatly less irritating to the skin.
