Vliv jezdce na délku kroku u koně
VRABČEKOVÁ, Monika
The mechanics of movement is one of the performance indicators of horses. It is influenced by internal and external factors. This thesis analyses how the rider's proficiency effects the length of steps of a walking and trotting horse. This experiment involves five horses of different breeds from ZF JU Ceske Budejovice and four riders of different proficiency levels (beginner, intermediate, advanced and a professional).These parameters were tested using video recordings: walking speed, the length of the step, the elevation height of the front left leg and the back left leg, the angle of the nose to the ground and the angle of the cheeks when walking and trotting. Measurements proved that the rider's proficiency and ability has statistically very high effect on the mechanics of the horse's movement, especially in relation to the elevation height of the legs, the length of the steps and speed. As the rider's proficiency level increases the walking speed and the elevation height of the legs also increase and the steps become longer. The nose angle got close to 90° with an increased level of rider's proficiency and the level of the angle of the cheeks decreased.The biggest differences were found between a beginner and a professional on a trotting horse. The differences were smaller when the horse was walking rather than trotting, however they still showed the same trend.The results found show that the rider has a significant effect on the mechanics of movement. A horse with a rider of higher proficiency can achieve better results and is able to demonstrate its abilities better. This can be used in races, exhibitions or horse sales.

Objektivní hodnocení mechaniky pohybu hříbat chladnokrevných koní
KOČVAROVÁ, Ivana
Goal of this study was to assess movement mechanics quality of cold-blooded breed foals (being bred in rearing houses), determine changes in movement mechanics as the breeding advances, and spot possible differences between the cold-blooded breeds in an objective manner.Quality of movement was tracked in two breeding houses in the years 2014 and 2015 and 48 stallion foals aged one, two and three years were included in this study. 24 stallions were of the breed Czech-Moravian Belgian horse, 15 Silesian Noriker and 9 Noriker. All stallions had been weighed in three-month intervals, 13 body measurements were taken and video technology was used to record their movement while being led. Recording was used to determine stride length and height span of right front and right hind leg movement. 354 measurements have been evaluated. Walk characteristics were determined at standardized movement speed of 75m.min-1. Foals bred at an altitude of 650 m were found to have flatter and longer strides than those bred at an altitude of 420 m. The outcome of inter-breed comparison was that Silesian Noriker have the longest stride, while Noriker have the biggest limb movement span. As foals grew older, stride length got slightly longer, while the limb movement span remained without major alterations.

Performance evaluation of Oldkladruby horses
IGNATOVA, Natalia
Horse breeding has always been favored over the other sectors of animal husbandry. Oldkladruby horse, bred in the Czech Republic for more than 400 years, is one of the oldest breeds of horses. This original breed is included in animal genetic resources. The aim of this thesis was to evaluate the results of Oldkladruby horse performance tests. The database was formed by descendants of fathers in breeding process in 1994 - 2014. The work follows the five factors reliability in heavy draught, team of horses maneuverability, marathon, movement, rideability and overall performance. Performance test is an important factor when selecting individuals for breeding, as well as a basis for determining performance of horses. Emphasis was placed on the analysis of monitored indicators and eventually on evaluation of the mechanics of movement, which is very important for Oldkladruby horses. Rudolfo, Roma and Siglavi Pakra strain represented a small number of individuals and their values are regarded as indicative. The largest number of mares which have undergone performance testing, belong to Generalissimus strain in the white color horses and Solo and Sacramoso colored black. Low values of the variation coefficient were found for all groups of mares and show considerable results balance. The results showed that for Oldkladruby mares in the mechanics of movement when comparing color variations, the highest marks reached strain Generalissimo. Due to the small number of stallions in the evaluation, we compared only their color variation. The low coefficient of variation indicates that the performance of stallions reached high level. When comparing the results of mares and stallions, we found that stallions excelled in all disciplines evaluated over mares.
