Training abdominal muscles will not affect the growth, muscle growth is due to intense, large, continuous exercise, so that the muscle fibers are constantly damaged, repair, muscle fibers are composed of muscle cells, muscle cells are stable cells that are non-renewable cells, will not be stimulated by exercise damage, will become hypertrophy due to stimulation. There are many factors that affect a person’s height, such as diet, sleep, growth environment, psychological factors, etc., and genetic factors also have a relationship. The main reason is the long bones, the ends of the long bones are called epiphyses, and the young retain transparent cartilage components called epiphyseal cartilage, epiphyseal cartilage cells continue to divide and proliferate so that the long bones continue to grow, which is the main reason why people grow taller. In adults, the epiphyseal cartilage ossification and normal bone stem fuse into one, so adults will not grow taller. If you want to grow taller, before the epiphyseal cartilage is ossified, ensure a good diet, adequate nutrition and various dietary fiber intake and vitamin supplementation, as well as a healthy living environment, reduce psychological and stress, and appropriate exercise will promote the growth of the human body.
