Why is swimming the most perfect sport in the world?

1, preventing falls A new study published in the American Journal of Epidemiology shows that for the elderly, continuous swimming is more helpful to prevent falls than other sports. The results show that men who swim are 33% less likely to fall than men who engage in other sports. In addition, swimmers have better standing balance ability.

2. Joint protection

When swimming, the body floats in the water, and the joints are not loaded, and the load is the least. Swimming (such as breaststroke) can ensure joint activity and exercise muscle strength, which is a good exercise method.

3. Reduce asthma attacks

Swimming in water, human body temperature is different from water temperature and air temperature. Therefore, regular swimming can improve the regulating function of the nervous system to body temperature, improve the adaptability of human body to cold and hot climate changes, especially to low temperature, improve children's physique and physical disease resistance, and reduce asthma attacks.

4, prevention and treatment of cervical and lumbar diseases

When swimming, due to the buoyancy of water, the spine of the body can be changed from the original upright state to the horizontal state, which greatly reduces the burden on the spine, thus effectively reducing the pressure in the cervical and lumbar intervertebral discs.

Moreover, the water flow has a certain "massage" effect on the spine, muscles and skin, which is also an important reason why many athletes with bone injuries or lumbar muscle strain choose hydrotherapy.

5, improve immunity

When swimming, the constant beating of water waves on the body can play the role of whole body massage, thus promoting blood circulation, improving insulin resistance, accelerating human metabolism, promoting digestion and absorption of nutrients, further enhancing physical fitness and improving immunity.

Step 6 lose weight

When people swim, the resistance in water is 12 times that in air. Overcoming these resistances depends on consuming a lot of energy, which consumes some lipids and glycogen stored in muscles and liver, thus achieving the effect of losing weight.
