When we do fitness exercises, our muscles relax and contract regularly. When muscles relax, the peripheral blood vessels dilate and congestion. When muscles contract, peripheral blood vessels contract and blood volume increases. Stop to rest immediately after fitness, the heart is still pumping blood efficiently, while peripheral blood vessels dilate, the area of vascular bed increases, and blood accumulates in peripheral blood vessels, resulting in a decrease in blood volume. At this time, the heart is in an ischemic state, peripheral vascular blood cannot flow back to the right heart to exchange gas with the lung, peripheral tissues and cells are in an anoxic state, and metabolic wastes cannot be eliminated. In severe cases, vasogenic shock will occur. Therefore, it is against the basic principles of physiology to rest immediately after fitness.
Therefore, after the fitness, we should do some cushioning exercises to prevent the body from feeling uncomfortable because of sudden stop of exercise. Some aerobic exercises can relieve physical fatigue and increase our fitness effect. Buffer movement should pay attention to the following issues.
First, you can do jogging and other sports after fitness to promote blood circulation and remove blood stasis.
Second, the cushioning exercise should be appropriate, not too intense, which will help the body recover. At the same time, you can sort out the gains of this fitness.
Third, if the fitness intensity is great, you should do full-body relaxation exercise. Two people can help each other.
Fourth, the cushioning exercise should focus on preventing impact, and the content should be related to the initial fitness exercise.
In short, you can't rest immediately after fitness. You should do other exercises to relax your body. This is the correct way to keep fit.
