What should I do if my running leg hurts suddenly?

The cause of pain after exercise: It is because of the accumulation of lactic acid, an intermediate product produced during glucose metabolism in the body during exercise. Because the exercise is relatively excessive and exceeds the intensity of anaerobic exercise, lactic acid produced in the body cannot be further decomposed into water and carbon dioxide in a short time, and anaerobic metabolism is formed due to insufficient oxygen supply, which leads to the accumulation of a large amount of excess lactic acid in the body.

There are two main ways to solve soreness: one is to promote the decomposition of lactic acid by increasing oxygen supply, and the other is to promote blood circulation to metabolize accumulated lactic acid as soon as possible. (This process is called acid excretion)

The main ways of discharging acid are as follows:

1.

Jogging allows muscles to have sufficient aerobic metabolism and accelerates lactic acid decomposition.

2.

Massage and stretching can relax muscles, soften stiff muscles after exercise by physical means, and promote blood circulation.

3.

Hot compress, hot bath or sauna can promote blood circulation and lactic acid metabolism.

4.

Sleep, deep sleep is the most effective way to recover.
