The goal of this study was to evaluate the physiological, hematological and biochemical changes that occur in police working dogs during a treadmill incremental exercise test. Ten animals were submitted to an incremental exercise test, comprising five stages of six minutes each, at increasing speeds of 6, 7, 8, 9 and 10 miles per hour and at an inclination of 5%. Blood samples were collected at rest (T0), immediately after exercise (T5) and after a 20 minutes rest period (T6), to determine complete blood count, urea, creatinine (Creat), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), lactate dehydrogenase (LDH), total plasma protein (TP), albumin (ALB), cholesterol (Chol), triglycerides (Trig), calcium (Ca2+), sodium (Na+), potassium (K+) and chloride (Cl-). Values for BL, HR, RT and glycaemia were measured at rest, after each test stage and after the rest period.
Significant variations were recorded between T0 and T5 in red blood cells (p<0.01), hemoglobin (p<0.01), AP (p<0.01), Trig (p<0.05), Ca2+ (p=0.02), Na+ (p=0.01), K+ (p<0.01) and Cl- (p<0.02). Significant differences were observed in BL at T5 (p<0.02) and T6 (p<0.02), RT at T2-T6 (p<0.01), HR at T3-T5 (p<0.01) and glycaemia at T2-T4 (p<0.01) and T5 (p<0.05).
The present results consist, to the authors’ knowledge, in the first description of the changes in physiological, hematological and biochemical shifts of physical fit police working dogs during an incremental exercise test. They provide valuable information for exercise monitoring and future training planning and performance evaluation.
