It is recommended to take more rest, supplement calcium and exercise moderately.
According to recent research, ultra-intense exercise makes young people's bodies in a state of hypoxia, thus releasing a large number of free radical compounds in the body. This will lead to delayed development and make your height lower than the normal development level. Athletes are high-risk groups affected by this, especially fitness athletes and wrestlers. They need to get stronger quickly, but they don't do it step by step.
For adults, hypoxia generally only causes some muscle pain. But for teenagers, free radicals produced by exercise will inhibit the activity of some important growth hormones. The research on some wrestlers in high schools found that the height of these students would be below average, and there would be other abnormal phenomena during their growth. This shows that the influence of high-intensity exercise on growth hormone is completely different from that of conventional exercise, which includes swimming, playing football and baseball. In fact, gradual exercise can help teenagers get rid of hypoxia. If you exercise like this, you can achieve the same exercise purpose, but there will be no adverse consequences.
Professor Saiwen of the University of California also confirmed this view through the study of teenagers. He asked some subjects to try their best to ride bicycles for 8 minutes and found that there was obvious evidence that these teenagers were in a state of hypoxia. But if these young people rest every 2 minutes 1 minute, they can achieve the same exercise effect, but they will not exceed the "hypoxia threshold". He stressed that this study does not mean that teenagers should not exercise. However, in order to make the growth and development unrestricted, it is necessary to exercise regularly and step by step. He pointed out that if children and even adults exercise excessively in a short time, the adverse consequences will last for a long time.
I found this on the internet, too. I hope it will help you.
