In this case, you should do a little massage before going to bed on the night after exercise, and taking a hot bath can also have a certain effect (but soaking in hot water for a long time will make your muscles tired and weak), which can speed up your metabolism, make the lactic acid accumulated in your muscles gradually be transported away by blood, and the muscle ache will gradually disappear.

If you don't treat it that day, your muscles will be sore the next day. It's no use doing any treatment at this time, only waiting for it to recover itself.

These muscle groups may be painful and stiff after untrained people take part in strenuous activities. This symptom usually appears after stopping exercise 12 hours, and it is more harmful the next day, and then gradually relieves, and the symptoms disappear after 4-6 days. Muscle pain may be caused by injury, especially the injury of muscle connective tissue and connective tissue attached to tendon.

Secondly, the production of histamine and other substances can also cause swelling and pain. After the damaged tissue is repaired, the muscles will become stronger, and even if they exercise more vigorously in the future, they are unlikely to be damaged again. Generally speaking, centrifugal muscle contraction makes muscles ache more easily than centripetal muscle contraction. Muscle soreness after exercise is called delayed muscle soreness.

Most methods relieve muscle soreness by stretching and lengthening muscles, which may be due to the stimulation of Golgi's golgi tendon organ of muscles and the suppression of impulses.

From the central point of view, pulling muscle can change the excitability of the corresponding center, block the spasm caused by excessive excitement of muscle spindle through negative pulling reflex, and improve the local tissue ischemia caused by spasm, thus improving the blood flow of muscle and promoting the recovery of damaged tissue.
