Abstract

The aim of this study was the objective measurement and evaluation of one of the most important part of the jump the stifle-hock-fetlock angulation. Movement analyses on twelve one-year-old foals were conducted of the same breed grown up at the same location with repeating the tests at the age of three. The foals worked individually each in a hall measuring 22 x 42 m where there was a 12 m long free-jumping corridor formed without a sidewall along the longer wall of the hall with one oxer jump in the corridor. The digital camera used to do the recordings (29 photos/sec) was set up 12 m from and in line with the first element of the oxer jump. The recordings were evaluated by using a Szelektor HDPG 02 program developed by ourselves. Fór the purposes of mathematical analyses and diagrammatic presentation the movement sequences were subdivided intő their elements and the key movement elements were given coordinate values, i.e., value scores by making use of so called marker scores. The stifle-hock-fetlock angulation above the hurdle of the hind limbs pushing off depends on the intensity of the push off. At the age of three the changes in the angles of the more outstretched stifle-hock-fetlock during the time period between the peak of the trajectory and the landing of the forelimbs are smaller and the further closing of the closed stifle-hock-fetlock angle with weaker jumpers is more significant.
