Reason: Muscle ache is caused by insufficient oxygen supply during muscle exercise. The anaerobic decomposition of muscle glycogen releases energy for muscle contraction. When sugar is decomposed anaerobically, a metabolite called lactic acid is produced. If not eliminated in time, lactic acid will accumulate in muscles and blood. Muscle soreness can be caused by tissue ischemia and hypoxia, acid stimulation, muscle injury or muscle spasm caused by exercise and other factors.

Solution:

1, relax after exercise. After exercise, you can lie on the sponge mat or rattan mat and rest for a while. When lying flat, your feet should be placed slightly above your head or even at the same height as your head. Never lie on the ground with water vapor. After a short rest, you can do handstand or handstand against the wall for 3- 10 seconds, which can be done several times, which is beneficial to the blood return of lower limbs to the heart. Then shake your limbs, first shake and pat your thighs or upper arms, and then shake your calves or forearms.

2. Massage after exercise is an important means to eliminate fatigue. The main methods of massage are shaking, needling, rubbing, patting and rubbing. The first is to shake the limbs, mainly to relax the muscles of elbows, knees and limbs.
