Abstract

The purposes of the study were 1) to examine indices of sexual maturation in athlete girls having predominantly endo-, meso- and ectomorph physique; 2) to demonstrate alterations in somatotype by breast maturation. 813 pubertal athlete girls (aged between 10 and 17 years) belonging to different sports events were studied. Somatotype was determined by the Heath–Carter method. Somatotype dominance was decided arbitrarily: the cut-off point was 4.75 unit for the dominant component. The other two components were minimum 1.5 unit below the dominant one. Breast development was rated according to Tanner’s suggestions. Data for menarche were collected by “status-quo” method. The age medians of maturation indices were calculated. Athletes with endomorph dominance matured the earliest. Mesomorphs started to develop their sexual characteristic later than endomorphs and had the latest completion of breast maturation. Girls with ectomorph predominance matured the latest and the fastest. Meso- and ectomorphs preserved their dominant component during breast maturation. Similarly to normal pubescent girls, they increased their relative fatness, but in a different rate. Staying in the mesomorphic endomorph field, endomorphs did not change their body form as maturation proceeded.
