It is said that children can't grow taller by practicing martial arts, is it true?

I don't think it's true because my brother has been learning martial arts since he was a kid, and doesn't practicing martial arts strengthen the body? Children more exercise to promote bone development, in order to grow taller. Generally the reason why children can't grow taller may be hereditary, or it may be because of malnutrition, and nutrition can't keep up is the most crucial factor. Children in the growth of the body stage, the body's nutrition is necessary to replenish on, miss this stage, it is difficult to grow taller.

The physical quality of children practicing martial arts is much better than that of ordinary children, so I don't think there is a situation where practicing martial arts affects their height. Many athletes, for example, are almost never short because they are constantly training and exercising. It's the same with kids who learn martial arts, they have to train a lot, they have to practice the basics, so it doesn't determine their height.
