Swimming is considered to be a sport that contributes to the effective treatment of osteoarthritis because in the water, the gravity decreases. When swimming, most joints in the legs and spine are not affected by body weight. During swimming, groups of back muscles are strengthened, joints are better than nourished exercise, can restrain and reduce the degenerative process in joints, reducing the frequency of relapses of the disease. When swimming due to the great resistance and heat conduction properties of water, it consumes a lot of energy, thus reducing the excess body weight, helping to reduce the additional burden on the muscles and joints, especially the knee and hip joints, and lumbar spine.

Exercising at chest-level water can help reduce the tension in the joints by 75%. Swimming is also very useful for those who want to recover from joint injuries, increase the endurance of the body.
When swimming, water pressure plus muscle pressure press on the blood vessels to help blood flow back to the heart and lungs. Due to the pressure of water on the swimmer's chest, restricting the inhalation and exhalation, strong breathing is necessary, helping to develop the respiratory system and increase the living capacity of the lungs. The higher the capacity of the lungs to live, the greater the ability to endure in labor and movement, create favorable conditions for breathing, and reduce asthma attacks, especially for smokers.
Regular swimming can help lower blood pressure and cholesterol levels in the body. When swimming, will increase blood and oxygen supply to the lungs and muscles, enhance the cardiovascular system, and at the same time bring a positive effect in the release of carbon dioxide from the body, helping the body maintains stable blood pressure and reduces the risk of a heart attack or stroke.

A warm-up helps warm the body and tightens the muscles, bones, and joints, thus avoiding cramps as well as avoiding sudden colds when in the water.
Should spread evenly during the week, swim once every 2 days in a period of 25-30 minutes. Do not stretch too long in one session. Elderly people often have unstable blood pressure, so they should not dive deeply, because then the increased pressure under the water greatly affects the breathing rate of the lungs and heart rate.

Before swimming, only snack and swim for 1 hour after eating. It is advisable to stay hydrated before, during, and after swimming.
