Eliminate excess fat
When people swim in the water, they will generate a lot of body heat. In addition, the human body constantly moves in the water, and the energy consumption of the body is greater. In order to maintain the balance of the body, the body needs to mobilize a large number of stored energy substances to accelerate the decomposition and supplement the heat lost and consumed by exercise. In addition, when swimming, the body is stimulated by cold water, which will reflexively cause thyroxine secretion to increase strength. Thyroxine can be stimulated by cold water, which will reflexively increase the secretion of thyroxine. Thyroxine can achieve the purpose of losing weight and maintaining normal weight.
(2) reducing the concentration of plasma cholesterol
Swimming can promote the increase of high-density lipoprotein content in plasma, and high-density lipoprotein is the nemesis of cholesterol. It not only participates in the reverse transport of cholesterol, but also urges plasma sterols to return to the liver for transformation and utilization. When its content is sufficient, it can also peel off the cholesterol deposited on the arterial wall, thus regulating the plasma cholesterol concentration and helping to prevent arteriosclerosis.
(3) Enhance the function of returning to camp.
When swimming, water waves have the massage effect of beating and squeezing the skin and blood vessels, which is beneficial to venous blood return, accelerating blood circulation, being extremely beneficial to heart work, reducing the burden on myocardium, helping to improve the microcirculation function and nutrient supply of myocardium, making myocardium more developed and contracting more powerfully.
(4) An ideal method to treat chronic diseases.
Patients with chronic arthritis, who exercise in water, use the buoyancy of water to make their leg joints in a relaxed state, so that they can flex freely and exercise comfortably, which is better than jogging. Because when jogging, patients must support their weight with their feet, and their joints are always in a state of tension. Although they are positive, the effect is halved. Swimming can also improve blood circulation and metabolism of limbs, and reduce bone and joint hyperplasia and muscle soreness. Asthmatics can also benefit from swimming. Because the air on the water surface is fresh and moist, there is no strong irritation or other substances that cause allergies. As long as the water temperature is well controlled, it is not easy for patients to induce asthma when swimming, and it can also prevent bronchospasm caused by other exercise methods.
(5) Swimming can regulate brain function and relax muscles.
Busy work, dizziness, swimming in the water for dozens of minutes, suddenly feel refreshed, clear-headed, work efficiency will certainly be greatly improved.
Therefore, for most people, swimming is the best way to keep fit.
