Acid-Base Alterations in Barrel Racing Quarter Horses of Different Fitness Levels Assessed Via The Simplified Strong Ion Approach

Introduction The evaluation of acid‐base balance of horses is important because it detects alterations that affect their performance and health. There are studies relating these changes with endurance type effort, but few regarding sprint exercise. The purpose of this study was to determine whether...

Description
Summary:Introduction The evaluation of acid‐base balance of horses is important because it detects alterations that affect their performance and health. There are studies relating these changes with endurance type effort, but few regarding sprint exercise. The purpose of this study was to determine whether the fitness level of Quarter Horses performing barrel racing could be differentiated by quantitative acid‐base analysis. Methods For this purpose, 10 horses were distributed into two groups: high (HF) and lower (LF) fitness as defined by the trainer. GPS and frequency meter were used for the measurements. Venous blood gas analysis was performed using a portable analyzer (I‐stat) before and after exercise. Strong ion difference (SID), anion gap (AG), strong ion gap (SIG) and concentration of non‐volatile buffers (Atot) were determined. Variables before and after exercise were compared within and between groups by t‐test (P
