초록

The purpose of the study was to investigate the body composition, energy metabolism, and serum lipoprotein profiles in female ballet dancers before and after a ballet performance. The subjects were cluster sampled 43 female ballet dancers of which 9 from an amateur ballet company, 15 from a semi‐professional company, and 19 from a professional company. The bioelectrical impedance method was used to measure the BMI, %BF, TBW, and LBM. The computer aided nutrition analysis program and 24‐hour recall method were used to measure the energy intake and expenditure, and physical activities for 7 days before and 7 days after a ballet performance. The serum lipoprotein profiles of LDL‐C, HDL‐C, TG, and the TC/HDL‐C ratio were examined by Enzymatic Colorimetry Method. The Analysis of Covariance and Multiple Range Test were applied to statistical significance. The results showed that there were significant differences in the BMI, %BF, EE among three ballet groups(p<.05), but not in the TBW, LBM, EI, LDL‐C, HDL‐C, TG, and TC/HDL‐C ratio. In conclusion, professional ballet dancers exert very high levels of energy expenditure in preparation for the performance while limiting their energy intake in order to decrease their very low levels of body weight and fat.
