Long-term lack of exercise reduces people's metabolic function, which easily leads to various muscle and joint diseases, such as scapulohumeral periarthritis and osteoporosis, and also leads to adverse physical reactions such as decreased cardiopulmonary function. Sedentary is also the bane of hemorrhoids, sciatica and pelvic congestion.
Lack of exercise or sedentary behavior will reduce human resistance and make people susceptible to diseases, which is an independent risk factor for the onset of type II diabetes. Lack of exercise can accelerate aging and increase the mortality rate of the elderly, and the incidence of myocardial injury, stroke, diabetes and angina pectoris has increased significantly.
Experts from the World Health Organization clearly pointed out that lack of exercise is the main cause of illness and death and one of the most unreasonable lifestyles. On the occasion of World Health Day, Dr. Brundtland pointed out that the lack of adequate physical activity will have serious consequences for human health, and about 2 million people around the world will die every year.
Hypertension, angina pectoris, stroke, peripheral vascular disease and myocardial ischemia are all very common cardiovascular diseases, and these various cardiovascular diseases are the number one killers in industrial society. Whether in the United States, Canada, Britain, Australia and other countries with high degree of industrial automation, cardiovascular disease is the leading cause of death.
A large number of statistical data show that the above diseases are more or less related to lack of exercise, and people who exercise regularly have less risk of coronary heart disease than those who lack exercise. Many studies have found that people who have been engaged in static work for a long time have a higher incidence of heart disease than the average person. Therefore, lack of exercise will increase the risk of coronary heart disease.
On the basis of searching a large number of literatures, the American Heart Research Association pointed out: "There is sufficient evidence to show that a sedentary lifestyle is more risky than hypertension, high cholesterol and smoking." A recent study also confirmed that among 15000 college graduates, the mortality rate of those who exercise regularly is much lower than that of those who lack exercise.
This study also shows that people who exercise regularly in their spare time can reduce the risk of coronary heart disease if they consume a considerable amount of calories every week. Therefore, actively participating in harmonious sports is one of the best ways to reduce the risk of heart disease.

Exercise for health, exercise for fitness. Fitness and health complement each other and are indispensable. However, if the fitness exercise and physical exercise are improper, it may make people sick.
Let's talk about the dangers of excessive exercise.
Excessive exercise is a common sports disease in sports, and its incidence ranks first among all kinds of sports diseases at present. Its harm to the body involves cardiovascular system, nervous system, respiratory system and endocrine system.
Excessive exercise will have the opposite effect on athletes' physical and mental health, sports performance, and middle-aged and elderly people who exercise to keep fit.
In recent years, sports medicine experts have found through animal experiments that excessive exercise can cause ECG changes, T wave inversion and abnormal rhythm, and a few people have atrioventricular block. Repeated intensive training will also reduce heart function and even cause myocardial infarction. Excessive exercise can also reduce immune function, reduce immunoglobulin and hemoglobin in blood and increase cortisol. Extreme fatigue exercise can also affect the lipid peroxidation of myocardial mitochondria.
This shows that excessive exercise is harmful to health. But how to identify whether the amount of exercise is excessive? It can be judged from the history of sports training, athletes' physical and psychological symptoms, and can also be judged comprehensively by biochemical tests such as electrocardiogram. Middle-aged and elderly people should insist on moderate exercise, and regular physical examination and adjustment of exercise amount are sure to be good for their health.
The essence of exercise is to keep the human body in a positive and energetic state, and "excessive" or "insufficient" is harmful. The essence of sports is to strive for practical results and avoid flashy; The essence of sports lies in faith and perseverance. Only in this way can we resist patients and live a long life in Corning.
