“…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).…”

“…The reduction in the HCO 3 concentration was due to the need of buffering by these increased H + protons (MARLIN & NANKERVIS, 2002), justifying their reduction at T1 and without full recomposition to normal concentrations in T2, which lowered the pH at T2 (Table 1). Decrease in cBase at T1 (P<0.05) may have occurred due to the reduction of HCO 3 -, because this is the most quantitative and important H + buffer in the organism (CARLOTTI, 2012), confirming that the variation in the cBase can accompany the HCO 3 direction variation in horses after exercise (KUPCZYNSKI e SPITALNIAK, 2015;LINHARES et al, 2017).…”

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.

“…(Table 3). This decrease occurred because, besides using the HCO3̄ to buffer the increase in H + prótons, the organism also requires bigger carbon dioxide elimination (CO2) from the body, reducing the pCO2, and base actions that reduce the pCO2 and body cBase value, to control the metabolic acidosis, confirming that the CBase value can accompany the direction of HCO3̄ in horses after exercise (LINHARES et al, 2017). Due to this, the cBase also decreased in the horses after concluding three sprints, CBase or base excess (EB) represents the base accumulation or nonvolatile acid in the blood, excluding the plasma HCO3̄ and the hemoglobin concentration in the blood (LIDINGER and WALLER, 2008).…”

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.

“…Another study found a sudden upsurge of lactate concentration after 15 min of recovery [ 49 ]. The horses with high lactate concentrations showed better results than those with low lactate levels, indicating that other mechanisms may be involved in the regulation of blood lactate concentration [ 50 ]. Nevertheless, postrace blood lactate concentrations were higher than pre-race ones for all horses; however, they were elevated more in the Arabian horses than in the Žemaitukai breed, probably owing to the significantly higher anaerobic capacity in the Arabian horses.…”

Fédération Equestre Internationale (FEI) has described equine endurance racing as the second largest discipline in the world, above which is only show jumping. The Žemaitukai is an ancient indigenous Lithuanian horse breed known since the 6th or 7th century. The Arabian horse breed is one of the oldest human-developed horse breeds in the world. Compared with other race horse breeds, the muscle tissue of Arabian horses is characterized by significant differences in structure—a predominance of oxidative fiber type I is observed in Arabians, making them the prevailing breed in endurance racing. The Arabian horses are recognized as the leading breed in endurance competitions. Speed, pace, and total time in the race strategy have been extensively studied in human sports, and in contrast, this strategy appears to have been virtually ignored in equestrian sport, despite the potential for contributing to performance optimization. In relation to speed and total time in the race, there are limited data on postrace physical, biochemical, and blood gas parameters of endurance horses. Thus, this study was carried out to investigate the effects of speed on the blood parameters of the Arabian and Žemaitukai horses during an endurance race. Blood samples were taken before and immediately after the exercise. Biochemical and blood gas indicators were analyzed. The study showed significant increases in mean blood gasometrical indicators, such as partial carbon dioxide pressure (8.09–15.18%, p < 0.001); base excess in the extracellular fluid (14.01%, p < 0.001 in the Arabian horses and 172.01% in the Žemaitukai breed, p = 0.006); decreases of the blood electrolyte ionized calcium (4.38–8.72%, p < 0.001) and the hematocrit and hemoglobin values (20.05–20.12%, p < 0.001 in the Arabian horses and 6.22–6.23% in the Žemaitukai breed, p = 0.003–0.004); and decreases in the base excess in the blood values (29.24–39.38%, p < 0.001) and lactate (13.45–31.97%, p < 0.001) in the blood of both breeds in the post-competition horses. Significant increases after competition were determined for the values of creatinine (21.34–30.82%, p = 0.001–0.004), total bilirubin (50.84–56.24%, PH < 0.001), and albumin (2.63–4.48%, p = 0.048–0.001) for both breeds. For the faster Arabian horse breed, recovering after racing took half the time that the local Žemaitukai breed did.
