12-year-old began to exercise, 17-year-old has become a muscle man, early training will affect growth?

As parents pay more and more attention to education, the age when they should be carefree to play is replaced by various cram schools. From a young age, domestic teenagers have been busier than adults, lack of exercise and excessive nutrition, so children’s obesity has become the most urgent social problem to be solved. < p > < p > What are we doing at the age of 12? Paul’s 12-year-old left his schoolbag after school and ran to play with his friends. Many 12-year-old children continue to participate in various interest classes in addition to their homework after school. In foreign countries, there is such a teenager who throws down his schoolbag and starts to exercise after school. < / P > < p > at the age of 15, he was already a muscle man, and began to participate in various bodybuilding competitions. His name was tristyn. He was a Vietnamese American. He played football all the time when he was very young. He wanted to improve his muscle strength and play football better. When he was 12 years old, he began to go into the gym for strength training. After contacting strength training, he went on the “no return road”. < / P > < p > his love for fitness has reached the level of obsession. He trains 5-6 times a week, day after day, and his persistence and love also give him the best return. His figure changes very quickly. After three years of systematic training, he has become a stable muscle man from that thin child. < / P > < p > and he posted his picture to the social networking site, and his body, which is not in line with his age, has become the focus of attention. Now he is a million fans of fitness. Now he is 17 years old, his muscles are very full, and he has become a bodybuilder. Many fitness gods will praise him as “the future of bodybuilding”! < / P > < p > many people admire him, but they don’t think that early strength training will affect children’s growth. For example, weightlifters are not trained well since childhood. Is this really the case? To solve this problem, Paul brings today’s fitness science popularization from the perspective of bone growth mode. < / P > < p > the bones in our impression are like sticks. It’s hard to imagine that they can grow. However, bones are also organs of the human body. They also have blood vessels, supporting and hematopoietic functions. < / P > < p > some of the connective tissue in our body is replaced by bone tissue, from slowly forming bones, the skull and clavicle of the body are mostly formed in this way, so children’s heads are soft. < / P > < p > when we were still a fetus, most of the bones of the body were just cartilage. With the growth of the body, after the subjective conscious activity, the two sides of the cartilage in the body slowly grew out of the adventitia. With the continuous growth of the adventitia, the cartilage would be wrapped, and then through the body’s nutrition input, a circle of dense bone was finally formed at the outermost part. < / P > < p > this growth process will continue until we are 23-25 years old, or even longer. But with the growth of age, the cartilage in the plate will be gradually replaced by bone tissue, and the epiphyseal plate will also become. Its change marks that the bone stops growing and the height of human body will also grow. < / P > < p > the so-called common sense tells us that strength training will press down on bones, making bones unable to grow. In fact, on the contrary, bones like to face pressure. Continuous pressure from the outside will improve bone structure and increase bone mineral density. In the face of external pressure, bones will produce a series of reactions to increase bone density and hardness. Bones and muscles are the same If the bone is under little pressure, it will grow very slowly. In fact, strength training not only does not affect development, on the contrary, it is more conducive to the growth of bones. Our common sense is also wrong cognition. The children who practice weightlifting are very short, and those who play basketball are very tall, which has nothing to do with the sport itself. However, when selecting, the small children will perform well in weightlifting, and the tall children will perform well in the training process It has been eliminated. < / P > < p > not only strength training, but also any sports can help the growth and development of bones. The World Health Organization has proposed that adolescents aged 5-17 need to accumulate more than 60 minutes of moderate or high-intensity sports every day. More than 60 minutes will provide better bone growth. At the same time, we should pay attention to adequate sleep and rich nutrition, which can stimulate the most possible Hair bone potential, let the child grow tall. Focus
