초록

The purpose of this study was to determine the effect of pyridoxine supplementation with ballet exercise on cell blood components osteocalcin(Os), and total cholesterol/high density lipoprotein cholesterol ratio(TC/HDL-C ratio) 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 three groups, i.e., GroupⅠ(n=4): placebo(2.4mg/day); GroupⅡ(n=5): pyridoxine(1.6mg/day); GroupⅢ(n=5): pyridoxine(2.4mg/day) with ballet exercise 3-5 times per week. Study subjects measured white blood cells(WBC), red blood cells(RBC), hemoglobin(Hb), osteocalcin(Os), and total cholesterol/high density lipoprotein cholesterol ratio(TC/HDL-C ratio), before and after the treatment. Analysis of Covariance (ANCOVA), Multiple Range Test(Scheffe), and analysis of simple regression were used to determine the statistical significance. There were no group differences in the osteocalcin (Os), and total cholesterol/high density lipoprotein cholesterol ratio, and hemoglobin. but WBC and RBC were significantly changed(p<.05). The result of this study does not lend support to the contention that pyridoxal phosphate intake has much practical impact on ballet exercise performance as a ergogenic acid. However, it does appear that several significant research topics in pyridoxine biochemistry metabolism as well as ballet exercise and nutrition can be explored profitably in the future using experimental designs involving interaction between pyridoxine status and exercise performance.
