Physiological and biochemical responses and hydration status in equines after two barrel racing courses

Abstract: Studies on biochemical constituents and hydration of horses in training or competitions are essential for the knowledge of their adaptive physiological and metabolic responses to the type of exercise inherent to the sport. The present research evaluated the effects of exercise on hydric status and physiologic and biochemical profiles in Quarter Horses during a barrel race training session. The design consisted of three evaluation times (T): at rest, before the start of physical activity (T0); immediately after… Show more

“…The increases in RR, pulse, HR, and RT observed in the present study are consistent with similar responses in Surti buffaloes [ 47 ], bullocks of Hariana cattle [ 24 ], and equids [ 20 , 48 ]. The increase in HR during exercise occurs in response to increased metabolic rates due to adrenaline and glycolysis; and also due to an increase in cardiac contraction to maintain an adequate blood flow for perfusion and tissue oxygenation, which is related to the increase in RR and pulse [ 43 , 49 ]. The change in body temperature is due to heat production resulting from muscle contraction during work [ 24 ].…”

“…The values of glucose concentration in horses' blood vary depending on the intensity and type of exercise, but they move within the reference intervals (Hodgson and McKeever 2014). Physical activity induces dehydration which leads to changes in the concentration of total proteins (Trailović 2008), creatinine, urea, bilirubin, electrolytes, and calcium, which negatively affects sports performance in horses (McCutcheon and Geor 1996;Allaam et al 2014;Gomes et al 2020).…”
