The following are some detailed explanations, please refer to:

This kind of muscle soreness, which usually appears 24 hours after exercise, is called "delayed muscle soreness" in sports medicine. The pain peaked 24-72 hours after exercise and basically disappeared after 5-7 days.

After strenuous exercise, especially after long-distance running, all skeletal muscles will have delayed muscle soreness. Long-distance runners will have pain in the extensor and flexor muscles of their hips, thighs and calves, especially at the distal end of the joint between muscles and tendons. After extreme exercise in hot summer, besides muscle pain, there will be symptoms such as dehydration, low calcium and low protein.

Most people think that excessive use of muscles will lead to muscle soreness.

The reason is:

1, the sharp increase of muscle tension and elasticity will cause physical damage to muscle structural components.

2. With the increase of metabolism, the toxicity of metabolic waste to tissues increases.

3. The neuromodulation of muscle changes, causing muscle spasm and pain.

How to prevent it?

1, the exercise schedule should be reasonable. After a period of exercise, the symptoms of muscle soreness were alleviated. And be single-minded. For example, downhill exercise can relieve muscle pain caused by downhill exercise after a period of time.

2, local warm rubbing medicine. Washing with warm water after exercise can relieve muscle soreness. Topical oil, ointment or liniment can also relieve pain.

3. Stretching muscles can relieve soreness. Stretching muscles can accelerate the relaxation of muscles, relieve antagonistic muscles and help the recovery of tense muscles. This kind of muscle stretching exercise also lays a foundation for preventing strain during exercise.

4. Make preparations and organize activities during exercise. Adequate warm-up activities and reasonable finishing exercises are helpful to prevent or relieve muscle soreness.
