1, long-term excessive exercise will make people mentally dependent.
A lot of exercise will increase a kind of "morphine-like substance" produced by human body, which will be released into the blood in large quantities, which will make people feel excited and can inhibit all kinds of discomfort and pain. After a long time, you will become addicted. Once you stop exercising, you will feel depressed, depressed, excitable and anxious.
2. Excessive exercise will damage the body's immune function and affect health.
When people exercise vigorously, they will produce immunosuppressive proteins, which will also cause apoptosis of immune cells, reduce the number of immune cells, and eventually lead to the decline of the body's immunity. When the body's immune ability is reduced, it is easy to suffer from colds, pneumonia and gastrointestinal infectious diseases when encountering germs and viruses.
3. Excessive exercise will lead to the decline of athletic ability.
Excessive exercise reduces the functions of various organs and systems, increases the incidence of exercise-induced anemia, and can cause insufficient exercise ability, decreased reaction ability, decreased sense of balance and decreased muscle elasticity. At the same time, it is accompanied by symptoms such as loss of appetite, insomnia, irritability, constipation, depression, anxiety and cold, which may affect the normal exercise ability. At the same time, excessive exercise may also lead to excessive wear of human joints and increase the risk of joint injury.
4. Overloaded strenuous exercise can cause accidents.
Overloaded exercise makes the cardiac circulatory system overwhelmed, and the amount of blood and oxygen needed will suddenly increase, but the supply will be relatively reduced. In this state of ischemia and hypoxia, athletes' hearts will suffer from acute ischemia, which will lead to cardiac arrest and cerebral blood flow interruption.
Precautions in sports
1, following the principle of gradual development of sports.
In a complete fitness plan, the intensity should be from small to large, the movements should be from easy to difficult, from simple to complex, from slow to fast, from short to long, and so on, so we must not rush to achieve success.
2. Warm up and relax before and after exercise.
Make full preparations before exercise to improve the excitability of the body and the flexibility of the joints. After the main exercise, pay attention to organize activities to promote muscle relaxation and smooth breathing.
3. Arrange diet reasonably before and after exercise, and fully supplement nutrition in time.
Such as timely hydration during and after exercise; After long-term aerobic exercise, carbohydrates, high-quality protein and various trace elements should be supplemented in time; More attention should be paid to the full intake of nutrients such as protein and sugar before and after strength training. Reasonable arrangement of diet and nutrition is of positive significance to the full storage of energy in the body, which can delay the appearance of fatigue and accelerate the recovery of physical fitness.
