The intensity of gymnastic elements together with specific sport training should be reflected in the morphological parameters of the gymnasts. The objective of the study is to analyse the somatic parameters of female sport gymnasts in the pupil competition cat-egory and to compare them with the values of regular population in the corresponding age group. The study included 16 gymnasts (average age of 10.7?1.2 years) and 227 girls (average age 10.9?0.9 years), which were in the controlled group. The parame-ters monitored were body height (BH), body mass (BM), body mass index (BMI), body fat (BF), total body water (TBW), skele-tal muscle mass (SMM), and visceral fat (VFA). Statistical signif-icance was determined in all monitored parameters and practical significance was also confirmed. When compared with the con-trol group, the gymnasts have lower BH (diff -9.7 cm), BM (diff -10.1 kg), BF (diff -14.4 %), VFA (diff -36.9 cm2) and higher ratio of TBW (diff 10.8 %), SMM (diff 7.9 %).
