Reaction time of sports horses.
KERNEROVÁ, Nina
In this thesis were charted information and methodology about reaction time of horses on optical stimulus. As an optical stimulus was used vehement and unforseen movement by white board (500 x 500 mm) on which horses reacted very well. Reaction scanning was made by high-speed video camera MotionScope 9400, which was connected to a computer. In total was evaluated group of 35 horses. The average age was 5.8 years, the average reaction time on optical stimulus was 152 ms. In experiment was group of 14 thoroughbreds and 21 warmbloods. Group contained 4 stallions, 17 geldings and 14 mares. The largest group was represented by 5 years old (10 representatives). By the thoroughbreds was found out reaction time 154 ms, by the warmblood group 150 ms. Differences between breeds were not statistically significant. The lowest average reaction time was measured out by stallions (139 ms), then mares (149 ms) and the highest rate was by geldings (157 ms). The difference between reaction time of geldings and mares was not statistically significant. The lowest rate was measured out by the age group from 2 to 4 years old (142 ms), then group of 6 to 13 years old (156 ms). The highest rate had group of 5 years old (159 ms). The differences between age groups were not upholded as statistically significant. The correlation coefficient expressing relation between age of horses and reaction time on the optical stimulus was found out very low, that means that it is not statistically significant. In this thesis was proved, that as well as humans, horses react more quickly on acoustic stimulus than on optical stimulus.
