Resumo
Search and rescue dogs require intensive training. The knowledge of the electrolytic and energetic changes that occur in these dogs is important to establish methods and actions to improve performance and reduce changes during physical activity. The aim of this study was to evaluate the hydration parameters, electrolytes, hormones, glucose and lactate concentrations with and without hydroelectrolytic and energy supplementation, in dogs submitted to 60 minutes of training. Six healthy dogs, trained and carrying out search and rescue activities, were evaluated in seven times and two different moments. Hydration parameters, such as body weight (BW), body temperature, hematocrit (Ht), red blood cell (RBC), hemoglobin (Hb)), total protein (PT) and albumin were determined; energy indicators such as glucose and lactate; electrolytes such as potassium (K+ ), sodium (Na+ ), chlorine (Cl- ), phosphorus (P+ ), calcium (Ca2+ ) and magnesium (Mg2+ ); and hormones such as cortisol, aldosterone, and insulin. In both moments (M1 and M2), after training (T60"), dogs presented isotonic dehydration, determined by erythrocytosis, weight loss, with no changes in K+ , Na+ , Ca2+ , albumin, cortisol and aldosterone. In the recovery phase, in both assessment moments, there was a significant increase in temperature and lactate, there was also a significant reduction of insulin, PT and P+ . Clreduced in M1 and increased in M2, while Mg2+ reduced in M1 and did not change in M2. Dogs showed recovery in R30", with values close to the basal (T0). It was concluded that both water supply and hydroelectrolytic and energetic supplementation, provided by the enteral administration, were capable of correcting the isotonic dehydration presented by dogs. However, supplementation was able to raise the serum values of Cl- and Mg2+ after exercise, without altering other electrolytes. Temperature and lactate concentrations increase after exercise and return to baseline with recovery. Insulin reduces after training, with no changes in serum glucose levels
