What do you know about the causes of muscle fatigue?

Most people will feel very tired after strenuous exercise, sometimes a lot of sweating, abdominal and calf muscles will be very sore, especially on the second day after exercise, some people can't even get out of bed to move, the body is extremely painful, some college students seem to be paralyzed after military training. In fact, these are all muscle fatigue caused by excessive exercise.

If a person usually does not exercise much, suddenly have to go through a lot of exercise or exercise for a long time, their body will be very tired, especially the muscles will also feel very tired, mainly because the exercise lasts for a long time, muscle glycogen will be broken down and provide energy for exercise, but because the storage of muscle glycogen is relatively limited, if it has been consumed in large quantities, it will definitely make the muscles fatigued. After a period of exercise, short-term high-intensity exercise that relies on glycolysis to provide energy will produce lactic acid, which will interfere with muscle contraction if it remains in the muscles for a long time, resulting in muscle fatigue.

The cause of muscle fatigue may be caused by an excessively strong exercise pattern, and high-intensity short-term exercise is likely to cause muscle contraction. Glycolysis and oxidation in the metabolic system limit the body's ability to work muscles, resulting in localized fatigue. If you want to exercise, don't exercise for too long, and don't have high-intensity exercise in a short period of time, otherwise the body will not be able to adapt for a while, which is likely to cause muscle fatigue.

Muscle fatigue occurs when muscles work repeatedly and their ability to do things decreases. The occurrence of fatigue during exercise is related to the intensity of muscle work, as well as the amount of oxygen in the cells. Muscle fatigue occurs when muscles work repeatedly and their ability to do things decreases.

The occurrence of fatigue during exercise is related to the intensity of muscle work. High-intensity anaerobic exercise makes muscle fatigue occur faster; During low-intensity aerobic exercise, muscle work can be maintained for a considerable period of time without fatigue.

The exact cause of this muscle soreness is not fully understood.

Most people believe that the overuse of muscles can cause muscle soreness due to the following reasons: 1. The sharp increase in muscle tension and elasticity can cause physical damage to muscle structural components.

2. The increase of metabolism and the increase of the toxicity of metabolic waste to tissues.

3. The neuromodulation of muscles is changed, causing muscle spasms and causing pain.
