The Compare of The Rate of BMD and Strength Muscles among two Groups Athletic (Taekwondo)and Nonathletic

Osteoporosis is a disease that causes bone to be broken and leaned. One of the effective ways of preventing osteoporosis is doing regular exercise from childhood. The aim of this experiment was to investigate the bone mineral density (BMD) and bone mineral content (BMC), Muscular strength and Anthropometric characteristics of athletic girls (Taekwondo) and compare them with nonathlethic girls.13 Athletic girls (taekwondo) with mean height (161/6±5/61), mean weight (56/2±5/1) and mean age of (19/69±2/78) were compared with control group including 12 non athletic girls with mean age of (19/69±2/78) were compared with control group including 12 non athletic girls with mean height (160±4/19), mean weight (52/8±6/64) and mean age of (21/5±1/9). Bone mineral density (BMD) femur (Wall and Neck) and lumbar (L2,L3,L4) measured throughDEXA method and muscular strength of hamstring and quadriceps (concentric contraction) were measured by means of Kin-com Apparatus. Data were Analyses at 15% level through SPSS package.
