How Much Energy Vaquejada Horses Spend in a Field Simulation Test?
Abstract: Vaquejada is a high-intensity and short-duration exercise in which helper horses (HH) are responsible to keep a bull running in a line while pull horses (PH) work to put the bull down after 100 m of running. The purpose of this study was to quantify and compare energy expenditures (EE), transport costs (COT) and metabolic energy requirements (Pmet) of horses used in Vaquejada. Thus, eight Quarter Horses, in randomly formed pairs, performed a vaquejada simulation test (VST), which consisted of three races on a sand track (130-150 m), with a 5-min interval between them. All horses used an integrated heart rate (HR) and GPS monitoring system (V800, Polar Electro) and, from these data, EE, COT and Pmet were calculated using the formulas: EE (J/kg/min) = 0.0566 × HR1.9955, COT = (HR-35)/kg/m × 103 and Pmet = (HR-35)/min/kg. Blood samples were collected for lactate analysis at rest, immediately after the first, second and third race and after 30 min of recovery. Data obtained were submitted to one-way ANOVA and Tukey tests (p ≤ 0.05). In VST, HH had higher EE and higher HR at trot; while PH presented higher EE and HR at canter. Finally, considering total VST, PH had higher EE and COT, while HH had higher Pmet. Lactate was higher in PH. Despite practicing the same sport, PH and HH should be considered distinct athletes, and these must be considered to set up appropriate physical and nutritional programs, which will lead to better performance and guarantees of well-being.

The research article investigates the energy expenditure and metabolic costs of horses used in Vaquejada, a high-intensity equine sport. The study finds that despite both being part of the same sport, pull horses (PH) and helper horses (HH) have distinct energy needs based on their primary activities in the game.
Subject and Research Method
- The research involved eight Quarter Horses performing a simulated Vaquejada test (VST) consisting of three races on a sandy track. These horses were randomly divided into helper horses (HH) and pull horses (PH). HH are responsible for maintaining a running bull’s direction, while PH work to take down the bull after it has run for about 100 meters.
- The heart rate and movements of horses were monitored using an integrated heart rate and GPS system (V800, Polar Electro).
- Blood samples were collected at different stages of the race for lactate analysis to evaluate the horses’ physical exertion levels.
Data Gathering and Analysis
- Energy expenditure (J/kg/min), transport costs and metabolic energy requirements of horses were calculated by measuring heart rates after each run.
- Data collected were then submitted to one-way ANOVA and Tukey tests to determine statistical significance.
Findings
- The study found that HH and PH present differing levels of energy expenditure and heart rates during the exercise. Specifically, HH had higher energy expenditure and heart rate at trotting speed, while PH had higher measures at cantering speed.
- PH had higher overall energy expenditure and transport costs during the VST, while HH had higher metabolic energy needs.
- The levels of lactate post-exercise were also higher in PH, indicating they incurred greater physical stress in the sport.
Conclusions
- The study concludes that HH and PH, while playing the same sport, have different energy and metabolic requirements due to their differing roles in the sport.
- These differences should be taken into account when creating targeted physical training and nutritional programs for the horses to improve their performance and ensure wellbeing.
