CHANGES IN LOWER LIMB BONE DENSITY IN YOUNG JUMPERS

ABSTRACT Introduction The research on the exercise effect human bone density and skeletal muscle content mainly focuses middle-aged elderly population. However, few studies different sports’ effects upon in college students adolescents. Objective Study of physical training lower limb jumping ability young people. Methods relationship between mineral was analyzed by mathematical statistics. Male individuals aged 10-20 years were divided into early adolescence group (n=26) late (n=37). According to status, they preadolescent athletic (n=11), non-athletic (n=15); puberty (n=11) (n=15). following indicators used: density, vertical jump test, continuous RDJ index. Results Athletes’ (BMD) is related their strength. These results suggest a certain internal connection tissue development Therefore, there evidence differences two groups. Conclusion Bone limbs adolescents correlated with ability. Exercise can help improve Evidence level II; Therapeutic Studies - Investigating results.
