The subject of the present study was the horse’s biomechanical response to training during the stationary 100-days performance test for Trakhener stallions. Ten stallions were filmed during the 100-days performance test, in the 62nd and 92nd day of training. Linear jumping stride parameters were measured for take-off and landing distances for each limb separately, as well as the differences between limb placement in pairs at take-off and landing were calculated. Data from the video image analysis were collected using a 25 fr/sec camera and measured by the manual Micro Station program. The parameters were filmed on a spread (oxer) obstacle of the height and width of 1.05 m, jumped three times by each horse. A total number of 60 jumps was analysed. The analysis of variance was performed using Mixed procedure of the SAS program with the random effect of the horse and fixed effects of the trial and successive number of the jump. The effect of training was significant for all take-off parameters and two parameters of front limb at landing. The effect of the successive jump was statistically significant for the landing distance of the hind non-leading limb as well as for distance between hind limbs at landing. The effect of the horse was significant for all the measured parameters. The effect of jumping training for the young horse at an early stage seems to be more important for the take-off than for the landing technique. It is also more significant for front limbs than for hind limbs.
