Most of rhabdomyolysis after exercise is due to excessive exercise, that is, muscle exercise overload. Aerobic exercise belongs to low-intensity exercise, so it generally does not cause rhabdomyolysis. However, it is not absolute. For example, when the exercise load of small muscle groups is overloaded, although it still belongs to aerobic exercise (the energy supply mode is mainly aerobic oxidation of glycogen), it may also cause serious damage to muscles and cause rhabdomyolysis.
Small muscle groups such as shoulders and arms consume less oxygen during exercise, so it is difficult to achieve anaerobic exercise even for a long time. Rhabdomyolysis may occur in small muscle groups after long-term high-intensity exercise, and the body may still be in aerobic exercise state. Therefore, aerobic exercise may also cause rhabdomyolysis, but it usually does not cause great harm to renal function because it destroys less muscle fiber tissue.
Excessive exercise can lead to rhabdomyolysis, but what is excessive exercise? Generally speaking, exceeding the range of physical load is excessive exercise. Exercise load includes exercise intensity and exercise duration. Excessive exercise is a relative value, such as the same exercise load, which may be a normal training amount for people who exercise regularly, but it will lead to excessive exercise for people who lack exercise.
Finally, we should pay attention to proper amount during exercise, replenish water, electrolyte and vitamins in time after exercise to promote the discharge of metabolic waste, but we should pay attention to the method of drinking a small amount of water many times.
