A total of 27 biometric measurements were taken on 80 horses. Horses were divided into three groups depending on their jumping predispositions. Among them there were horses known from their participation in national and international competitions. On the basis of the measurement results indexes were calculated and the Principal Components Analysis was performed. It was found on the basis of the obtained results that horses with high jumping abilities exceed the other groups in height at the withers and height at the croup, they had a longer region of the forearm and longer autopodial part of the fore limb. This indicates an important role of the length of III metacarpal bone and phalanges in the motor activity. Among traits of the hind limb, jumping ability is affected by the total length of the autopodial part of the limb. Moreover, the ratio between this part of the limb and the oblique length of the trunk is also important. On the basis of the Principal Components Analysis the uniqueness of the body conformation of some known sports horses was confirmed in comparison to the other investigated animals.
