  • Data are presented as mean±SD for normal distributed data and as median and IQR (25–75) for skewed data. Student's paired t test was used after skewed data were log transformed.

  • BD-score, body dissatisfaction score; BMI, body mass index (kg/m2); DT-score, drive for thinness score; EA, energy availability, EDI-3, Eating Disorder Inventory-3; FM, fat mass; LEAF-Q, Low Energy Availability in Females Questionnaire; T3: triiodothyronine; VO2peak: maximal oxygen uptake, ¤ determined by DEXA scan.
