Is swimming good for Cardiovascular?

Is swimming good for Cardiovascular? Swimming is a good exercise for your health. It not only has the effect of fitness shaping, but also helps to improve the cardiovascular system. Let's take a look at the cardiovascular benefits of swimming.

Is swimming good for Cardiovascular?

1. The buoyancy of water promotes blood circulation

In the water, the gravity of the human body is mostly offset by the buoyancy of the water, so that the swimmer can exercise in a horizontal position, and the pressure of the water on the skin makes the blood in the large vein easily flow back to the atrium, which is the body's Blood circulation creates good conditions.

2. Water resistance increases myocardial strength and blood vessel elasticity

When people swim in the water, they are hindered by the resistance of the water, so that the swimmers can exercise as much as they can on the land. It takes a lot of effort to get a certain speed, so it has a great influence on the human cardiovascular system, especially in the When swimming fast, the heart rate is greatly accelerated, and the output of the blood is 5 to 6 times higher than that of the quiet. This requires an increase in blood flow, and completes the blood circulation while overcoming the pressure of the water and the cold contraction of the microvessels. Thereby the strength of the myocardium is increased and the elasticity of the blood vessels is increased.


3. Cold water stimulation enhances blood vessel elasticity

When people are swimming, the water temperature is generally lower than the temperature on the ground. Due to the stimulation of cold water, the blood circulation and metabolism of the whole body are enhanced, the blood vessels of the skin are contracted sharply, a large amount of blood is sucked into the internal organs, and the visceral blood vessels are dilated, and the body is cold-resistant and the skin. The blood vessels will expand rapidly, and a large amount of blood will flow back from the viscera to the body surface, and the blood vessels will be stretched one by one to effectively enhance the elasticity of the blood vessels.

4. Low temperature effects of water enhance vascular reflex ability

The effect of cold water stimulation on the function of the cardiovascular system, but also the enhanced vascular reflex ability of cold stimulation, so that they respond quickly after encountering cold water stimulation, and the flexibility is improved. The long-term adherence to swimming exercise can thicken the blood vessel wall and increase the elasticity. , thereby delaying vascular aging.

5. Water impact massage delays blood vessel aging

Water is flowing. When swimming in the water, people's movements and water flow will cause the small arteries on the surface of the human body to be impacted by water, thus acting as a massage, which also helps to increase the elasticity of small arteries. Delays vascular aging.
