The scientific name of this kind of soreness is: delayed muscle soreness. It is caused by lactic acid accumulation and muscle microstructure destruction.

2. Lactic acid accumulation is caused by lactic acid in glycolysis metabolites during strength training; The destruction of muscle microstructure will heal in the recovery period after training, and the healed muscle will become thicker than the original muscle fiber. This is called the principle of excessive recovery, which is the driving force of muscle growth.

Generally, the cold compress lasts for 10 ~ 15 minutes, and the ice pack is separated from the skin with clothes or towels to prevent skin frostbite.
