The scientific name of this kind of soreness is delayed muscle soreness, which is caused by the accumulation of lactic acid and the destruction of muscle microstructure. Lactic acid accumulation is caused by lactic acid in glycolysis metabolism 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.

1, cold compress the target muscle immediately after heavy training in the early stage. Generally, the cold compress lasts for 10 to 15 minutes, and the ice pack is separated from the skin with clothes or towels to prevent frostbite. Or take a cold bath

2. Eating a lot of carbohydrates within 2 hours after nutritional supplement training can restore the level of muscle glycogen, so eat a meal within 2 hours after training.

3. Strengthening stretching is mainly to stretch the muscles in sore parts after training 12 hours, or when training other events the next day.

4, acid discharge training Acid discharge training is the training to eliminate excess lactic acid in muscles.

Data expansion: Fitness is a kind of exercise, such as all kinds of unarmed aerobics, rhythmic gymnastics, rhythmic gymnastics and all kinds of self-resistance movements. Gymnastics can enhance strength, flexibility, endurance, coordination and the ability to control all parts of the body, thus making the body strong.
