초록

The purpose of this study was to determine effect of ballet exercise capacity on bone lipoprotein, cell blood components, and body composition in female ballet dancers. 14 female ballet dancers were participated in 30days study for a double blind and subjects were randomly assigned to one of the tow groups, GroupⅠ(n=7): 15,000kcal(energy consume volume 500kcal/day); GroupⅡ(n=7): 15,000-30,000 kcal(500-1000kcal/day) with ballet exercise 3-5 times per week. Study subjects measured white blood cell(WBC), red blood cell(RBC), hemoglobin(Hb), hematocrit, osteocalcin, calcium, percent body fat(%), and total body water, before and after the treatment. The scheffe′s multiple range test and analysis of covariance(ANCOVA) were used to determine the statistical significance. There were no group differences in the calcium, red blood cell, white blood cell, hematocrit, and total body water. but osteocalcin, hemoglobin and percent body fat(%) was significantly changed(p<.05). In conclusion, it appears that exercise volume for 30days turn into osteocalcin, hemoglobin and percent body fat(%) in female ballet dancers. Therefore, an increased exercise capacity is inversely associated with reduced risk of developing osteopenia and body composition in female ballet dancers.
