여성 무용수의 체지방률과 식욕조절 호르몬의 상관관계

Abstract

This study was designed to determine the correlation between percent body fat and appetite-regulating hormone levels among Korean professional female ballet dancers. 86 Korean professional female dancers participated in this study. The percent body fat of the subjects was measured using the bio-impedance method. Blood samplings were assayed using RIA, ECLIA and Enzymatic method for ghrelin, leptin, insulin and glucose. Statistical analyses included linear regression and Durbin Watson Test. The results showed that the independent variables leptin(3.69±1.83 ng/mL) and insulin(4.08±2.02 μU/mL) significantly (p<.05) affected the dependant variable percent body fat, and leptin and insulin were positively correlated. The independent variables ghrelin(1089.9±38 pg/mL) and glucose(88.90±8.17 mg/dL) showed no significant correlation to the percent body fat. These data indicate that there are correlations among leptin and insulin and percent body fat, and that the female ballet dancers with higher percent body fat also had higher level of leptin and insulin.
