This study subjects consisted of 15 people who 13-20 careers in professional dancers to dance tape . Those who were big years apart in age from other subjects or who had any singularity were excluded for the study. Bone mineral density test was carried out through the measurement of the bone mineral densities in Lumbar 1~4, Femur Neck, Femur Trochanter, Femur Interochanteric Crest, by using Dual Energy X-ray Absorptiometry (DEXA). In the results, the level of the bone mineral densities of the style dancers shows high bone mineral densities on the excercise which requires more body weight pressure through the different level of test. At same time, the ballet, which continueously makes movement in full up situation and requires less body weight pressure, shows the lower bone mineral densities than Korea Dance and Modern Dance in spite of long term exercise. In fact, the style of dance determines the lever of bone mineral densities, and the excercise which need more body weigth pressure and power impacts the bone mineral densities
