This study has attempted to define the influence of movement pace of trotters onto their heart rate (HR). This influence is one of the basic problems in the selecting of training methods.
Additionally, the pace level was determined to keep the horse’s organism on the level of safe oxygen transformations. A telemetric recorder of heart rate was used in the research to define the HR in trotters within the movement pace between 15 and 35 km/h. Based on the analysed cases, three levels of HR scores were distinguished: 100–140 beats/minute „safe”, 141–170 beats/minute „threatening” and over 170 beats/minute „dangerous”. An increase of movement pace causing the growth of HR in trotters was noted, which was proved by average HR scores in particular speed ranges as well as the correlation coefficient. Their range was significant at P ≤ 0.01 in each case and reached the level between 0.785 and 0.951 (mares) and 0.849 to 0.984 (stallions). Trotters’ sex did not have a decisive influence on the pulse level at work with changing velocity, which mainly pertained to the second and third levels. Minimum velocity ranges causing anaerobic transformations in the organism were also distinguished. Based on that, it was established that training which includes the speed up to 17.5 km/h should keep the organism on the level of oxygen transformations. The threat of organism acidifying may occur at 18–21.5 km/h and anaerobic conversion may
occur at 22 km/h.
