In the actual stage, on international level and in our country, is growing the importance of horses for equestrian sports. The researches were carried out on sports horses from Romanian Sport Horse and English Thoroughbred breeds. In this study, in order to evaluate aerobe energetic capacity of the horses, by determining the value of VLa4, there was used a standard effort test. There was completed an instrumental method to determine the lactic acid, based on enzymatic reactions and Screen Master Plus spectrophotometer was used for analyses. In can be observed that only for heating stage of training, the average value of lactic acid increases from first test to the third test. At all other effort stages the situation is opposed. Testing the differences significations for the first two testing periods, it was find that between all compared values the differences are very significant. For the third testing period, for all compared lactic acid values the differences are significant, excepting the differences testing between the lactic acid values at 400 m/minute stage and 450 m/minute stage, where the differences are very significant.
