BIOMECHANICAL ANALYSIS ON THE EFFECT OF WEIGHTLIFTING TRAINING ON WOMEN'S HEIGHT
AbstractSUMMARY - In order to promote the development of weightlifting exercises of woman, the receive-stresses condition of trial lift at each moment were analyzed by using high-speed photographic method, the stresses distributions and the relationship between stresses on bone and lifting weight were studied. In the meantime, we investigated 75 woman weightlifting players from the whole country, the growth capacities of height are compared with the same age section of female, more over the reality heights are contrasted with the high of attainable in the light of heredity genetic factor. The result shows: Although the stresses in depth of trial lift on bone is more than ordinary person, the stimulation of stresses may play an important part in the growth of bone, that is within regular sphere, the stresses can promote the growth of bone. Of 75 woman players through 4 years training, the average growth capacity of height every years is 0.78 cm, which belongs normal sphere and reaches the heights in the light of heredity gene calculating. So weightlifting training doesn't hamper the growth of height, and it may play a positive role in that. Main reference. 1.
