Gymnastics arm pain may be a normal physiological phenomenon, or it may be a pathological phenomenon caused by over-exercise or improper exercise, such as rhabdomyolysis, muscle strains and so on. 1. Physiological phenomenon: under normal circumstances, the human body provides energy through aerobic oxidation. In the case of strenuous exercise, the energy provided by aerobic oxidation is not enough, the muscles in the arm will carry out anaerobic glycolysis to provide energy, anaerobic glycolysis makes a large amount of lactic acid accumulation, so that the arm produces a feeling of soreness and pain, which can be relieved by sufficient rest. 2. Rhabdomyolysis: If the amount of exercise exceeds the body’s load when jumping exercise, resulting in damage to the transverse muscle of the arm, the cell membrane is damaged, so that myosin flows into the bloodstream, resulting in rhabdomyolysis, which can cause pain in the arm. 3. Muscle strain: If there is no warm-up exercise before jumping gymnastics or the amplitude of movement exceeds the muscle load when jumping gymnastics, resulting in muscle tear, that is, muscle strain, will also appear in different degrees of arm pain. Jumping gymnastics arm pain, may also be caused by other factors such as cervical spondylosis, etc., such as pain persists, by rest can not be relieved, it is recommended that patients go to the hospital in time to check, clear cause, follow the doctor’s instructions for standardized treatment.
