Jumping rope can grow taller. There is a time limit for human growth, with the fastest growth in infancy, a stable growth period after three steps, the second peak of growth and development before puberty, and a slowdown after puberty. Height is not innate, heredity has little effect on height, but nutrition plays a leading role, so special attention should be paid to reasonable nutrition within 2 years old. In addition, exercise also helps children grow taller. The best exercise is skipping rope, which can stimulate the growth of bones. Improve bone circulation, stimulate growth hormone secretion and promote height. It is a scientific research achievement of the former Soviet Union that skipping rope can promote the growth and development of teenagers, but there is little hope that adults with closed epiphysis will grow taller by skipping rope. My cousin has grown 2 cm since he was 27, so many boys have not closed their epiphyses at the age of 20. If you want to know whether the epiphysis is closed, you can go to a regular hospital to make a bone age film. Advise friends who want to grow taller and lose weight: Please use scientific methods to make up for their shortcomings.

Finally, talk about the time and frequency of skipping rope. Theoretically speaking, strenuous exercise is not allowed before meals and one hour after meals. Some people want to lose weight and jump rope before meals to reduce their appetite. This is unscientific. The best time for human activities should be from 3 pm to 8 pm. Friends who want to improve their skipping skills should not do it during this time. I personally don't advocate morning exercise. Some people "smell chickens and dance" in the morning, even get up at three or four o'clock to exercise, and then go back to sleep. This is not only vulnerable to air pollution, but also makes the biological clock disorder, leading to fatigue and premature aging. Because the ground air pollution is the heaviest before sunrise, there is less oxygen at this time. After sunrise, the green plants start photosynthesis, inhaling carbon dioxide, spitting out oxygen, and the air is fresh. So don't jump rope after sunrise if you have time. Skipping rope should not be less than 4 times but not more than 6 times a week. You usually need a day's rest and thinking, so that you can improve faster. Each jump time should be controlled between 30- 100 minutes. Too little can't get the effect of fitness, and overtraining for more than two hours will make the body extremely tired.
