Exercise training session-induced metabolic acidosis in barrel racing horses

“…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.…”
