Purpose. The aim of the paper was to determine the occurrence of feet and ankle deformities in trampoline and artistic gymnasts. Methods. Ten acrobatic gymnasts (trampolinists) and 10 artistic gymnasts aged 6-14 years were recruited. The calcaneal-tibial (rearfoot) angle was determined as the angle of the upper calcaneal tendon and the longitudinal heel axis while Clarke angles were determined by podoscopy. Results. The trampolinists showed significantly greater medial angulation (calcaneal valgus) than the group of gymnasts. Right and left foot Clark`s angles in both the trampoline and artistic gymnasts were above 55°. Conclusions. Trampolinists exhibit significantly more pronounced calcaneal valgus than artistic gymnasts. The prevalence of foot and ankle deformities in both populations should be addressed by coaches in the gymnastics training of young children.
