1, the need to improve the physical fitness of the whole people. In the 2008 Beijing Olympic Games, China achieved the world 1 gold medal count for the first time, Japanese life expectancy was 1, and China ranked 8 1. The time for Chinese students to participate in sports is not as long as that in developed countries such as Japan, and the physical education class scores of Chinese students are generally on the decline. The proportion of the whole people participating in sports is much lower than that of the United States, western European countries and Japan, and most middle-aged and elderly people participate in square dance, so the effect of exercise is relatively poor.

2. In order to develop sports industry. The development of China's sports industry is seriously lagging behind, accounting for only 0.6% of GDP, while that of developed countries is 2%. Therefore, the State Council proposed to vigorously develop the sports industry and strive to reach 5 trillion yuan by 2025. This means several ambitious developments.

China has a population of nearly 654.38+04 billion. If the whole people exercise, referring to the proportion of 65.438+0.8 billion people participating in physical exercise among the 300 million people in the United States, it means that about 800 million people participate in physical exercise, which is really remarkable.

The so-called physical exercise is actually an item that makes people adapt to exercise. Subjectively exercising is actually to improve the adaptability and tolerance of the body to exercise items. Although after special training and exercise, the results will be improved, or even greatly improved, but the physical quality will not be improved. People who take part in physical exercise are not better physically and live longer than those who don't. China has a population of 200 million who take part in physical exercise all the year round, and the United States has 65.438+0.8 billion people, three times higher than China. But the average life expectancy of Americans is not much higher than that of China, which is about 3-4 years higher. There are also comprehensive factors such as a good environment and low life pressure. Americans live longer than China, not because the proportion of people who take part in physical exercise is high. The so-called students' physique is nothing more than the students' adaptability and endurance to exercise programs, and it is not a scientific standard to measure students' physique at all. This shows a problem, blindly participating in physical exercise, blindly extending exercise time and blindly engaging in national fitness can not achieve the purpose of keeping fit, which is tantamount to wasting time. It is a departure from the original intention and purpose of strengthening physical fitness by forcing people to improve their adaptability and tolerance through so-called fitness exercise.
