[Evaluation of the performance of horses using pulse rate loading dynamics after basic training].
On the basis of test results, regarding the pulse rate response to the increased load, obtained from 278 three-year-old horses after finishing their elementary training (145 Bohemian warm-blooded horses, 115 Kladrub Black horses and 18 English half-bred horses), a method was worked for the evaluation of their performance. As an evaluating criterion a velocity (v170) was chosen which was obtained from an experimentally determined regression dependence of velocity on the pulse rate at 170 pulses per minute. A set of v170 data were statistically processed and on the basis of quantiles of normal distribution for the used breeds the variance zones were computed which were evaluated with 1 to 10 scores. By this evaluation the degree of performance of the tested horse can be estimated with regard to the corresponding breed.
