BACKGROUND: Delays in bone age, the onset of puberty, and skeletal growth in gymnasts could be, in part, the reason for an interest in gymnastics, rather than being the result of vigorous exercise. We hypothesized that short stature and delayed bone age are present at the start of gymnastics, and training delays growth, producing short stature, even after retirement. METHODS: Sitting height and leg length were measured in 83 active female gymnasts, 42 retired gymnasts, and 154 healthy control subjects. Results were expressed as age-specific SD scores (mean +/- SEM). RESULTS: In the cross-sectional data, active gymnasts had delayed bone age (1.3 +/- 0.1 years), reduced height -1.32 +/- 0.08 S..
