Energy balance and body composition factors in adolescent ballet school students

Study design: Observational Study
Abstract: The aim of this study was to asses the impact of professional education in a ballet school on total energy expenditure, energy balance and nutritional status of pupils. In 44 girls (x age = 13±1) from a professional elite Dance School (BSD) and 29 girls (x age = 13±1) selected from a local primary school, constituting the control group (CG), daily energy expenditure (TEE) - by 24-h heart rate monitoring method (HR), and energy intake (DEI) - by 24-h dietary recall (record), were estimated. Subjects were also assessed for body composition using BIA method and simple anthropometrical indices, and skinfold thickness. The ballet school dancers TEE values were significantly greater than those of the control group (11.04±1.3 MJ/24 h vs. 9.47±1.3 MJ/24 h, p<0.001), while the DEI of the BSD was significantly lower than that of the CG (8.68±2.25 MJ/24 h vs. 9.52±1.38 MJ/24 h, p< 0.001). Thus, energy balance of BSD was far from even (-2.35±2.14 MJ/24 h). The energy balance results correlated with BMI, skinfolds thickness and body fat content data. All these parameters for the BSD were significantly lower when compared to the CG (BMI: 17.1±1.6 vs. 19.3±1.3; p<0.001, body fat: 14.5%±4.1 vs. 28%±2.9; p<0.001, skinfold thickness 7.0 mm±1.3 vs. 8.0 mm±1.1; p<0.001). The young ballet dancers were exposed to relatively intensive physical performance, had a high daily energy expenditure that was not compensated for by energy intake. The girls from the ballet school are prone to increased health risks due to prolonged negative energy balance.
