The degree of muscle soreness after exercise is different, and the reasons are different:
1, acute muscle soreness: lactic acid
When people do strenuous exercise, the decomposition of muscle glycogen is accelerated and the oxygen consumption is increased, so that the muscle is temporarily in a relatively hypoxic state. At this time, muscle glycogen can be converted into lactic acid through pyruvate and accumulated in muscle. The muscles that accumulate lactic acid will contract, thus squeezing blood vessels, making blood flow blocked and producing the feeling of muscle pain.
But lactic acid will be completely excreted in one or two hours after stopping exercise, so acute muscle soreness will not last long.
2. Delayed muscle soreness: it is muscle fiber injury.
Generally speaking, soreness peaks 24 to 72 hours after exercise. A strong ache may mean that the action is wrong, or it may be overtraining, or it may be because the training level of a certain aspect has dropped, or the muscles have more centrifugal contractions.
Extended data:
In daily life, you can prevent and eliminate the symptoms of muscle soreness by the following methods:
1, stretching exercise. Static stretching can accelerate muscle relaxation, relieve antagonistic muscles and help to recover tired muscles. Perform static stretching exercises on sore parts, keep stretching for 2 minutes, then rest for 1 minute, and repeat. Doing this stretching exercise several times a day is helpful to relieve spasm and lay the foundation for preventing strain during training.
2. Pat and massage. Pat and massage sore parts, relax muscles, promote blood circulation, help repair muscle damage and relieve spasm.
3. Local hot compress. Hot compress is the most effective method. Hot compress on sore local muscles can promote blood circulation, accelerate metabolism, and accelerate the relief and recovery of muscle soreness, especially with slight stretching or massage, which will accelerate the elimination of delayed muscle soreness and promote it to return to normal.
4. Take a proper rest. When the pain can't be eliminated or can't be eliminated slowly, you should take a proper rest. Because rest can slow down muscle soreness, and can slowly promote blood circulation, accelerate the elimination of metabolites, improve the supply and repair of nutrients in muscle soreness, and make it return to normal.
