With the rapid development of economy and science and technology, electrification, mechanization and automation have gradually replaced most of the human body's movements, which has gradually reduced the human body's movements. With the improvement of people's living standards, due to the gradual reduction of exercise, the intake of high fat, high sugar and high protein in the human body continues to accumulate and increase. Therefore, one less and one more make the normal metabolic function of human body decline, and the incidence of obesity, diabetes, hypertension, stroke and heart disease gradually increase; The function of the heart will also decline for more than ten years in advance because of one less, and the incidence of cancer is 7 times higher than that of people who exercise regularly; The incidence of arteriosclerosis, nephropathy, gallstones, osteoporosis and mental depression is also rising obviously.

As the saying goes, life lies in exercise, and exercise is an active means to improve human immune function, resist diseases and prolong life. Research data show that healthy people who exercise regularly have better cellular immune function and humoral immune function than ordinary people. "The way to keep fit is always to exercise less." Exercise is an essential factor to get rid of illness and prolong life, and it is also the need of life. Mainly in the following aspects:

1, exercise can enhance physical fitness: physical exercise can increase vital capacity, make gas exchange fully, increase oxygen content in blood and accelerate metabolism; Enhance the excitement and inhibition process of cerebral cortex; Strengthen myocardial fibers, strengthen myocardial contraction and improve myocardial oxygen supply; It can also improve the quality of sleep, reduce the pressure of life and reduce depression and anxiety; Preventing cholesterol from depositing in blood vessels can effectively prevent arteriosclerosis, hypertension and coronary heart disease.

2, exercise can prevent human organs from aging: regular exercise can promote people's blood flow, provide sufficient nutrition for cells in various parts of the body through microvessels, and delay the aging of tissues and organs. Enhance balance and endurance.

3. Exercise can delay brain aging: research has confirmed that after the age of 30, 654.38 million brain cells die every day; After 70 years old, only 1/3 remains in brain cells. For people who often exercise and are diligent in thinking, the cerebral vessels are often stretched, which slows down the aging of nerve cells and helps to improve memory and thinking ability.

4. Exercise can delay the aging of bones: improve the elasticity and toughness of skeletal muscles and joint ligaments, thus improving the ability of bones to resist stretching, bending, compression and torsion. Exercise can also improve the range, flexibility and accuracy of joint and ligament activities; Improve bone blood circulation, enhance substance metabolism, and increase bone organic components.

5, exercise can enhance the body's immune function: First of all, exercise can promote the body's metabolism more vigorously, thus avoiding the malignant transformation of aging cells in the body. Second, exercise can promote myocardial contraction, accelerate blood circulation in the body, and significantly increase white blood cells that devour bacteria, viruses and cancer cells in the blood, so that diseases can be eliminated more timely and quickly. Thirdly, endogenous thermogenic substances produced by the body during exercise can promote the increase of T lymphocytes in the body, and antibodies secreted by T lymphocytes can effectively annihilate cells and toxins invading the human body.

6. Exercise can improve the function of digestive system: promote the activity of rectus abdominis and abdominal wall muscles, strengthen the peristalsis of digestive tract and the secretion of digestive glands, promote appetite, improve the blood circulation of gastrointestinal tract, enhance the function of digestive glands, and massage the stomach. It is beneficial to the digestion of food and the full absorption of nutrients, reduces the occurrence of atrophic gastritis, and prevents gastroptosis, gastric neurosis, constipation, etc.

7. Exercise can improve endocrine regulation function: exercise can improve the metabolism of sugar in the body and prevent diabetes; Can lower cholesterol and prevent arteriosclerosis; It can control weight, promote the utilization of excess fat and prevent obesity.

8. Exercise can improve renal function and promote the excretion of metabolic waste.

9. Exercise can improve the function of reproductive system: due to the stimulation of endocrine system, especially gonads, people can maintain normal youthful vitality, improve sexual function and improve the quality of sexual life. Research shows that women over 40 who exercise regularly have a more harmonious sex life than women who don't exercise.

10, exercise can delay skin aging: skin health is a sign of bodybuilding. Skin aging is also a manifestation of body aging. Exercise can enrich the blood of the skin, and the blood can deliver oxygen and nutrients to the skin, making people radiant, full of vitality and preventing aging. To keep your skin fit, you should maintain it mainly from the aspects of exercise, nutrition and sleep.
