What is the exercise value of swimming?

Swimming is a relatively popular sport. It is not only a recreational sport, but more importantly, it can strengthen the body and is good for the overall health of the body. It can also increase the body's resistance and improve the body's ability to adapt to the environment, especially winter swimming. So what is the exercise value of swimming? Let us introduce it to you in detail from the following aspects.

1. Improve cardiovascular system

Swimming plays a very important role in improving the cardiovascular system. The stimulation of cold water can promote blood circulation through heat regulation and metabolism; in addition, the pressure and resistance of water during swimming also play a special role in the circulation of the heart and blood. The entire blood circulation system is improved, the diastolic blood pressure increases and the systolic blood pressure decreases in the static state, so the blood pressure value becomes more favorable; the elasticity of blood vessels is also improved.

2. Improve lung capacity

The strength of lung function is determined by the strength of respiratory muscle function. According to measurements, when swimming, a person's chest is subjected to a pressure of 12-15 kilograms. In addition, the cold water stimulates muscle contraction, making breathing difficult. This forces a person to breathe hard and increase the depth of breathing so that the amount of oxygen inhaled can meet the body's needs. Swimming promotes the development of respiratory muscles, increases chest circumference, and lung capacity. It also opens more alveoli during inhalation, allowing for smoother ventilation, which is extremely beneficial to health.

3. Enhance skin blood circulation

During swimming, the stimulation of cold water can cause the blood vessels in the skin to constrict, preventing heat from dissipating outside the body. At the same time, the body steps up to produce heat, dilates the blood vessels in the skin, and improves the blood supply to the skin. Long-term persistence can enhance the blood circulation of the skin.

4. Enhance immunity

The water temperature of a swimming pool is usually between 26 and 28 degrees. Soaking in water dissipates heat quickly and consumes a lot of energy. In order to replenish the heat dissipated by the body as quickly as possible to meet the needs of cold and heat balance, the nervous system responds quickly, speeding up the body's metabolism, enhancing the body's ability to adapt to the outside world, and resisting the cold. People who regularly participate in winter swimming are less likely to catch colds due to improved body temperature regulation function. It can also improve the body's endocrine function and increase pituitary gland function, thereby improving resistance and immunity to diseases.

5. Weight Loss

When swimming, the body is directly immersed in water. Water not only has great resistance, but also has very good thermal conductivity and dissipates heat quickly, thus consuming more calories. In addition, swimming can help prevent sports injuries to the lower limbs and waist. When exercising to lose weight on land, due to the heavy weight of obese people, the body (especially the lower limbs and waist) has to bear a great gravity load, which reduces exercise ability, makes people easily fatigued, and may damage the joints and bones of the lower limbs. Swimming is conducted in water, and a considerable portion of the obese person's weight is borne by the buoyancy of the water, which makes the lower limbs and waist feel much more relaxed, greatly reducing the risk of joint and bone injuries.

6. Fitness

Exercising in water reduces the impact of the ground on bones during ground exercise, lowers the chance of bone aging and makes bone joints less likely to deform. The resistance of water can increase the intensity of human exercise, but this intensity is different from equipment training on land. It is very gentle, and the intensity of training can be easily controlled within the aerobic range. It will not grow very stiff muscles, and can make the lines of the whole body smooth and beautiful.

This is all we have to say about the exercise value of swimming. It can be seen that swimming has many benefits. It can improve the cardiovascular system and lose weight, making it suitable for most people to practice. It should be noted that when swimming, you must pay attention to your personal safety and take protective measures.
