People who don't often exercise in life sometimes feel muscle soreness all over after exercise. People who often take part in physical exercise sometimes feel muscle soreness when they exercise too much, which is a normal physiological phenomenon.
In sports medicine, there are two kinds of muscle soreness caused by exercise: one is that the pain appears immediately after exercise, but it disappears quickly, which is called acute muscle soreness; The other is a few hours or a night after exercise, accompanied by fatigue, muscle spasm, stiffness and other symptoms. This kind of muscle pain disappears relatively slowly, and can not fully recover until 3-4 days or even 6-7 days. This symptom is called delayed muscle pain or post exercise fatigue.
We often say that muscle soreness mainly refers to the latter, namely delayed muscle soreness.
reason
In the process of participating in physical exercise, every action is completed by muscle contraction. A large number of energy substances in muscle (such as adenosine triphosphate, creatine phosphate and muscle glycogen) are decomposed to release energy for muscle movement. People who do not often take part in physical exercise have weak cardiopulmonary function and poor blood circulation, which makes a large amount of lactic acid produced by muscle contraction unable to be oxidized and eliminated in time, but accumulated in muscle and stimulate nerves in muscle, which will make people feel muscle pain. Of course, there is another view that connective tissue abnormalities are the biggest cause of delayed muscle soreness. This is a normal physiological phenomenon. It has no effect on physical health. It will disappear naturally after proper rest.
preventive measure
In order to reduce muscle soreness, the middle-aged and elderly friends who take part in physical fitness exercise for the first time must have a small amount of exercise and gradually increase it after their body adapts. If they already feel soreness, they don't have to stop exercise. They can appropriately reduce some amount of exercise and carry out local hot compress or hot bath after exercise, so as to promote blood circulation and relieve muscle soreness. After the muscle soreness disappears, you can gradually increase the amount of exercise. You should adhere to long-term physical fitness exercise, so that the cardiopulmonary function can be gradually improved, the supply of oxygen is sufficient, and the lactic acid can be treated in time, so the phenomenon of muscle soreness is not easy to occur.
