What are the dangers of excessive exercise

Sports are certainly good for health and can improve the body's immune system. But anything too much will be harmful to the body, so more than the amount of exercise will be harmful to the human body what long life?

Causes pathological bone resorption

Long-term high-intensity exercise will make the bone tissue should be stressed too much, pathological bone resorption, especially in the elderly, but also easy to cause fractures. In addition, long-term high-intensity excessive strain on the periosteum, can also lead to fatigue periostitis and cause fatigue fractures.

Articular cartilage nutritional disorders can occur

The normal structure and function of articular cartilage is one of the important factors to maintain the flexibility and normal movement of joints. Long-term excessive exercise, articular cartilage is often subject to microscopic damage, into the normal elastic change, resulting in cartilage nutritional disorders, accelerating the degenerative disease of cartilage. The accumulation of microscopic damage can cause cartilage ulcers, glass and other injuries.

Decreased skeletal muscle function can occur

Post-exercise muscle soreness is one of the common symptoms after extensive exercise, and acute or chronic overcompliance can lead to structural damage and dysfunction of skeletal muscle. Relative muscle hypoxia after strenuous exercise, accumulation of metabolites lactic acid, free radical production, and increased concentration of calcium ions in myocytes cause structural damage to myocyte contraction, increased protein degradation, decreased or impaired skeletal muscle contraction and extension function, increased muscle India and severe pain.

Induced myocardial ischemia

Excessive exercise makes the heart blood supply can not meet the demand of the heart itself to do work, thus causing myocardial damage, inducing cardiac insufficiency and electrocardiographic abnormalities, and in serious cases may also cause sudden death. High-intensity exercise may also cause blood flow disorders, which can lead to coronary artery endothelial damage, causing coronary artery spasm.

Causes autonomic dysfunction

Excessive exercise is likely to autonomic disorders, resulting in gastrointestinal dysfunction, such as many people in intense exercise fire after strenuous exercise stomach pain, lower abdominal cramps, nausea, vomiting, loss of appetite. In addition sympathetic nerve overexcitation, may also appear exercise hypertension.

Damage to the liver and kidneys

The blood flow of the body is redistributed during excessive exercise, muscle blood flow increases, and the blood flow of the liver, kidneys and other internal organs is correspondingly reduced, especially the liver and kidney function of the elderly have different degrees of decline. On this basis, if the long time or high intensity exercise, it will lead to different degrees of hypoxic damage to the liver, kidneys and other tissues.

Endocrine disorders

Excessive exercise will lead to endocrine disorders, the most affected are the hypothalamic-pituitary-adrenocortical axis and hypothalamic-pituitary-gonadal axis. Prolonged, high-intensity exercise suppresses hypothalamic and pituitary functions, causing endocrine disorders and a series of negative effects on the function of various systems.

Causes mental fatigue

A lot of exercise will lead to burnout, loss of appetite, memory loss, difficulty concentrating, and seriously affect life and work efficiency. Some people will also experience some mental symptoms, such as irritability, irritability, indifference to reaction, mental depression, etc.
