1, men need to earn money to support their families.
In the social culture of China, men are needed to support the whole family. And it's risky to play sports. If he doesn't make any achievements in this field, he will have no stable source of income. In this case, the gossip of the neighborhood is not enough for a man. Therefore, under the current social pressure in China, men are looking for stable jobs instead of engaging in sports. On the other hand, women have more space and time to arrange training and hobbies, so women have less pressure to engage in hobbies, so more women are willing to engage in sports. This is one of the reasons why women are stronger than men in China now.
Sports in China are too commercialized.
Take China Men's Football Team for example, it is too commercialized and full of shady speculation. Therefore, sports is no longer a sport, but a business activity of businessmen. In this case, people who engage in sports will become more and more complicated and will not take it as their own business. In this case, it is difficult to do well, which is also the reason why sports in China have been in a slump.
To sum up, the reasons why men's sports performance is poor now. Mainly because the current social atmosphere is not good, so the pressure and obstacles for men to engage in sports are relatively large.
