1, make the figure more perfect.
The whole body muscles participate in swimming, which can develop the body muscles in a balanced way. Swimming is a good aerobic exercise, which can consume excess calories, burn fat, reduce excess fat, prevent obesity, increase muscle content and form a body shape.
2. Enhance cold tolerance
Skin capillaries contract when stimulated by cold water. During exercise, due to lack of oxygen, capillaries will expand all over the body. Swimming will repeatedly contract and dilate capillaries, making the nervous system that dominates the expansion and contraction of skin blood vessels more flexible, enhancing its adaptability to temperature changes and enhancing its cold tolerance.
Step 3 strengthen resistance
Sticking to swimming can not only enhance physical fitness and improve immune system, but also prevent many diseases. Especially butterfly and breaststroke, pelvic muscles and thigh muscles are needed for swimming. Repeated butterfly and breaststroke can prevent uterine prolapse and bladder prolapse and delay genital aging.
Step 4 protect the spine
Swimming is equivalent to massaging the spine. In particular, patients with cervical spondylosis need to bear more pressure when doing other sports because of their own weight factors. When swimming, they can be floated by water. During exercise, the spine is in a stress-free state, and the neck muscles get some exercise, thus stabilizing the neck.
5, regulating endocrine
Swimming can alleviate the problem of endocrine disorders by regulating endocrine, relieve inner pressure and make the heart more calm. In addition, swimming can make skin smoother and more delicate, promote bone growth and prevent osteoporosis and rheumatoid arthritis.
6. Improve cardiopulmonary function
When swimming, the body needs a lot of gas exchange, which can accelerate the blood flow and exercise the pumping ability and vital capacity of the heart. When swimming, accepting water pressure factors to improve vital capacity, and persisting in swimming can improve cardiopulmonary function and reduce the probability of upper respiratory tract infection.
