1, muscle glycogen decomposition is accelerated, oxygen consumption is increased, and muscle is temporarily in a relative hypoxia state. At this time, muscle glycogen can be converted into lactic acid through pyruvate and accumulated in muscle.

2. Grape glycolysis produces a large number of intermediate metabolites such as lactic acid, which cannot be excreted through respiration, forming lactic acid accumulation. Too much lactic acid can make muscles feel sore and can be completely removed from the body within an hour or two after stopping exercise.

Matters needing attention

1, pat and massage. Pat and massage sore parts, relax muscles, promote blood circulation, help repair muscle damage and relieve spasm.

2, 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.

3. Take a proper rest. When the pain can't be eliminated or eliminated slowly, you should take a proper rest, because rest can slow down the muscle soreness, slowly promote blood circulation, accelerate the elimination of metabolites, improve the supply and repair ability of nutrients in muscle soreness, and make it return to normal.
