Aim: This study assessed the nutritional status and physical activity levels of 150 female students aged 10-18 from three top Polish ballet schools, where the most promising dancers go on to pursue professional ballet careers.
Methods: We analysed the girls' body composition, physical activity level (PAL) and PAL coefficient. The ballet students also completed a questionnaire.
Results: The results revealed large deficiencies in the body weight and body fat of the young ballerinas. The mean body mass index (BMI) for the group was 16.8 kg/m2 . Polish centile charts showed that 18% of the girls had BMIs below the norm and 54% had a lower than average body fat content, with a mean of 15.6%. The body fat content was lowest (13.8%) in the 13- to 15-year age group. On average, girls aged 10-12 had 15.7% body fat, while girls aged 16-18 had 18.4%. The mean values for the anthropometric measurements were higher in older girls. The majority (72%) of the respondents reported high physical activity levels, defined as more than 15 hours of exercise per week.
Conclusion: Special attention should be paid to low BMIs and body fat in young ballet school dancers aged 10-15 years.
