Generally, cardiovascular adaptations that occur in increase transport capacity and oxygen consumption in muscle during exercise in the horse are: increase of cardiac output (CO) by increasing heart rate (HR) and less systolic ejection volume (SV), redistribution of blood flow from inactive to the active territories, associated with increased venous return through muscle and respiratory pumps, increase the capacity of blood oxygen transporting with improved extraction and its retention in the muscles. A standard way of sport horses to respond to physical exercise is to increase cardiac output, possibly by increasing the HR and SV. The present paper analyzes the heart rate evolution and dynamic at 15 sport horses, during 3 periods of training. Assessment of heart rate was effectively executed indirectly (via stethoscope). Appreciated immediately after exercise heart rate increased in all 3 months of training proportional to speed, reaching a maximum of 81,86±1,14 cardiac movements / minute in the third month, at a speed of 550 m / minute and decreased at 10 minutes after effort, in all 3 months of training, reaching a minimum of 53,40±0,74 cardiac beats / minute in the third month at speed of 350 m / minute. Statistically the differences were insignificant in most cases were traced.
