“…Decrease in pH, HCO 3 and cBase with concomitant reduction in pCO 2 reinforced the occurrence of metabolic acidosis in the present study, corroborating the studies by SILVA et al (2009) who also reported decrease in these parameters in the venous blood of horses after submitting them to maximum exercise on a treadmill. The decrease in these parameters reaffirms the effect of lactic acid diffusion in the blood originating from the muscle cells under the predominance of the anaerobic glucose metabolism, causing lactic acidosis (MARLIN & NANKERVIS, 2002;BARBOSA et al, 2016;LINHARES et al, 2017).…”

“…Exercise intensity and duration determine which is predominant (CAIADO et al, 2011). Equestrian tests, where the exercise of high intensity and short duration, that require rapid energy production and adequate energy consumption to meet the demand of the intense muscular activity, and because it cannot be provided sufficiently by the aerobic pathway, requires the anaerobic pathway (BARBOSA et al, 2016).…”

“…Anaerobic glycolysis is the main anaerobic energy production mechanism (BARBOSA et al, 2016), and during this occurs endogenous production of acid, mainly lactic acid. The disassociation of lactic acid generates hydrogen protons (H + ) and lactate.…”

Exercise training session-induced metabolic acidosis in barrel racing horses

et al. 2020

In horses, acid-base balance disorders are common after intense exercise, with metabolic acidosis being the most common after high intensity and short duration exercise. Understanding the processes that cause them is fundamental for procedures, which aimed to improve the physical fitness of horses for athletic purposes, with fewer changes in homeostasis. The present study assessed the effect of barrel racing on acid base balance in Quarter Horse, at the following times: T0 - immediately before training; T1 - immediately after the end of the second course; T2 - one hour after the end of the second course. In T1, there was decrease (P<0.05) in the pH, HCO3 -, pCO2, cBase, tCO2 and strong ion difference concentrations, while the plasma lactate and anion gap increased (P<0.05). It was concluded that barrel racing training caused transient metabolic acidosis in the horses, and hyperlactatemia was still present after an hour of rest.

“…In the vaquejada there is a large demand on the horses to exert physical effort, with fast starts, sudden changes in direction and stops, and strength while pulling the steer down (LOPES et al, 2009;MENESES et al, 2014;SOUZA et al, 2017). Thus, as in other Western-type horse contests, the exercise the horse performs in the vaquejada is classified as high intensity short duration, demanding fast energy production and intake to support the big muscular effort, that makes the exercises predominantly anaerobic (BARBOSA et al, 2016).…”

The hydration status and biochemical profile were assessed and compared in two Quarter Horses groups (pull and helper), at three times (T) of a vaquejada training: at rest, before exercise (T0); after three sprints or races (T1); after an hour of rest from sprints (T2). There was no significant difference between the evaluation times in each group nor between the groups in the times evaluated for the parameters: capillary refill time, skin turgor, color and humidity of the mucosa, total plasma proteins, creatinine, urea and osmolarity, creatine kinase, aspartate aminotransferase, total calcium, phosphorus, and total magnesium. There was increase in the hematocrit and plasma glucose in both groups at T1, but without differences among the groups. The plasm lactate increased in T1. Only for plasma lactate there were changes between the groups, being higher in the pull at T1. It was concluded that, in response to the imposed exercise, the pull and helper groups showed similar hydration status with only slight dehydration, and maintained their biochemical rates preserved, except lactatemia which increased in both, but higher in the pull, suggesting that this group performs more intense anerobic metabolism in the vaquejada.

“…In horse sports where there is high intensity and short duration exercise, the organism intensifies anaerobic mechanisms, mainly the anaerobic glucose (BARBOSA et al, 2016), due to the need for rapid production and uptake of energy to give energetic support to the muscule work (VERMEULEN et al, 2017). Vaquejada is among the sports where anaerobic mechanisms are needed by the horses´ organism.…”

The cation-anionic and acid base status were assessed and compared among pull and helper Quarter Horses in three times (T) in vaquejada training: before (T0) and immediately after three sprints (T1), one hour after the end of the sprints (T2). At each time blood samples were collected for gasometry, plasma and serological analyses, and the differences were calculated of strong ions (SID), anion gap (AG) and weak ions (Atot). Sodium, potassium, chloride and Atot did not vary among the times or between the groups. In T1, ionized calcium (iCa), pH, HCO3-, pCO2, CBase and SID decreased in the groups, but not between them, while the lactate and AG increased in both the groups, and the lactate was higher in the pull horse group. Only iCa and lactate remained, respectively, lower and higher in T2, compared to T0. It was concluded that the exercise caused hypocalcemia, hyperlactatemia and metabolic acidosis in both groups, however, a greater lactic acidosis in the pulling, characterizing that in this group the anerobic metabolism was of higher intensity.
