Resumo
Rescue-trained dogs are used as aidin search operationsof living personsand/or corpses. Dogs perform intense physical activity during training sessions andoperations, that promotes a series of adaptive changes in the body. The term “athlete's heart” is used to describe cardiac morphological and functional changes that occur in athletes as a result of physical exercise, and physiological effects caused by exercise can resemble disease states. The aim of this study was to evaluate the cardiovascular responses caused by rescue training in dogs. Seven healthy dogs not practicing physical activity (sedentary group) were evaluated and compared to nine healthy dogspracticing search and rescue training (training group) at rest. Evaluations were also performed with the dogs of the training group before and after the search and rescue training. The animals were submitted to echocardiographic, electrocardiographic andsystemic systolic blood pressure (SBP) measurements.The data were statistically compared between the groups; as well as the comparison of the parameters evaluated in the different moments of the training group. The results demonstrate that the physical effort required by the training caused cardiac alterations in dogs, observed by the echocardiographic exam and not present in the electrocardiographic and SBP exams. As well as acute responses of the body through exercise that did not impair ventricular function nor cardiac arrhythmias after performing 20 minutes of physical exercise. Indicating a good physical conditioning of the dogs, making them apt to be used in real occurrences.These changes, similar to those described in human athletes, suggest that this type of training may cause "athlete's heart syndrome" in dogs.
