Abstract: 

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 through DEXA 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. Results showed that:
1- BMD of quadriceps between athletic and nonathletic was not different significantly. Although mean BMD of (L2, L3, L4) in taekwondo group were lower than nonathletic group (P>0.05).
2- Although mean BMD of femur of taekwondo group was greater than nonathlethic group but this difference was not significant (P>0.05).
3- Mean peak torque and power in hamstring and quadriceps muscles in taekwondo group was significantly greater than nonathlethic group (P<0.05).
The results of this research showed that these reversely useful effects of exercise while proper and balanced nutrition is also vital for having strong healthy bones.
