Introduction: Heart rates (HR) have been used to quantify the cost of transport (COT), and metabolic power (Pmet), defining energy expenditure (EE) in horses used in different equestrian sports. Differences between equine athletes must be well documented to properly manage training and nutritional programs. The aim of this study was to quantify and compare energy expenditure (EE), cost of transport (COT) and metabolic power (Pmet) of jumping horses and bullfighting horses in simulation tests.
Material and Methods: Five 9.8-year-old Lusitano horses, executed a bullfighting simulation exercise (BST), and other thirteen 11.5-year- old horses, performed a jumping simulation test (JST), both for ~5 minutes. During the exercise all animals used an integrated heart rate and GPS monitoring system (Polar M430/H10) and from these data, EE , COT and Pmet were calculated using matematical formulas. A descriptive data analysis was done for the comparison between equestrian disciplines.
Results: For BST it was recorded 127.9 bpm for HR, 128.24 J/min for EE, 114.06 bpm/kg/m.103 for COT and 4,958.66 bpm/kg for Pmet. Bullfighting horses reached Vmed of 3.8 m/s, HRmed of 99.0±29.2 bpm and HRpeak of 150.6±45.6 bpm. These results were higher than those observed during the JST. In this last one, it was recorded 90.3 bpm for HR, 67.15 J/min for EE, 88.79 bpm/kg/m.103 for COT and 719.00 bpm/kg for Pmet. Jumping horses reached Vmed of 11.6 m/s, HRmed of 85.6±20.9 bpm and HRpeak of 109.5±34.4 bpm.
Discussion/Conclusion: Comparison between show jumping exercise and bullfighting showed that the last one is a more intense exercise, although it is performed with a lower speed. Further, effort was more intense due to the relentless search for the bull, with constant and sudden changes in direction.
