Kosenko S. The ability to work of trotting horses with different types of higher nervous activity

This thesis presents the results of researches the growth dynamics, the indicators of the ability to work and the biochemical parameters of carbohydrate metabolism in blood of trotting breeds horses with different types of higher nervous activity and using differentiated methods of their training. The horses of strong balanced movable and strong balanced inert types of higher nervous activity are characterized by the highest levels of ability to work. The horses of strong unbalanced type also have high spirited potential but it can be determined only with using certain ways of assembly and training methods. The horses of weak type of higher nervous activity according to the results of our researches have shown the least ability to trotting tests. According to the biochemical researches the horses of strong balanced movable and strong balanced inert types have more balanced carbohydrate metabolism and they are characterized by the effective mechanisms of its regulation. In the horses of strong unbalanced and weak types metabolism is strongly influenced by sport's stress that leads to imbalance of energy processes in cells because of stress influence. The differences in physiological and biochemical processes in trotters body of different types HNA depending on the load scause the need for using training works of different intensity levels that will help them to be maximally spirited without any negative consequences related to the nervous system's disorders.
