The evaluation of foals jumping abilities.

The aim of this work was pass judgment the jumping abilities of foals measured at freestyle jumping during one's year. By the help of videorecording and subsequently computer analyses was assessed 427 jumps in free scope performed by 6 mares and 6 stallions in year-class 2002, 2003, 2004. Video records were made out by digital video kamera CANON type DM {--} XM 2 E. Processing of video records is done through the use of a programme for work with digital video records Pinnacle Studio 9. Movement mechanics analysis is practised in a programme Lucia 32 G Version 4.11. Following parameters were observed during a jump: jump bow characterized by 4 angles formed deciding physical parts, maximum flexion of the forelimbs {--} carpal joint and fore fetlock joint, rise of the forelimbs, flexion of the hindlimbs above a jump - knee-joint, hock joint, hind fetlock joint, location of the maximum carpal flexion. To objective assessment was made evaluation by statistical packet R version 2. 2.4.1 (2006) with usage procedures of Linear Models and there was verified demonstrativeness of differences among particular horses. It is evident from the findings, that jumping abilities of horses during the horse rearing are approximately same, but some of the qualities may change by training. . The objectively values found out during judging of a jump by way of video analysis make it possible to gain more accurate pieces of information about jump abilities of a horse and these pieces of information are usable in breeding of horses for a show-jumping
