The effects of fatigue on endurance horses' metabolism

Abstract

Research on the biochemical blood indicators of performance horses is presented here. Dehydration, cytolysis syndrome, uremic
syndrome, and electro- lyte imbalance are all symptoms of the metabolic syndrome, which develops in horses after exercise due to an
inadequate supply of energy to the organs and tissues. Horses' cardiac output should be measured before, during, and after exercise
since that's when dormant diseases first show themselves clinically. Understanding how the metabolic processes in a horse's body
change in response to different levels of physical exertion is crucial. Metabolic problems and cardiovascular dysfunction are the
leading causes of exclusion from competition for horses. The study set out to examine post-exercise alterations in biochemical blood
markers in performance-oriented horses. Research subjects were horses, which are used in the equestrian disciplines. The general
analysis and biochemical characteristics of blood were studied in all horses to characterize the functional status of the organs (heart,
liver, and kidneys). Overexertion manifests itself most often in horses as increased weariness, dyspnea, tachycardia, and less often
arrhythmias. Dehydration (hyperproteinemia), uremic syndrome (increased concentration of urea and creatinine), cytolysis syndrome
(increased activity of AST and ALT), and electrolyte imbalance (decreased serum sodium and potassium) all manifest themselves in
exercise-induced muscle damage in performance horses. Changes in the permeability of cardiomyocytes and exit enzymes in the
circulation are caused by the hyper- lactatemia that occurs in horses during exercise and may play a crucial role in the pathophysiology
of myocardial dystrophy. Pre-exercise metabolic syndrome in horses may be detected with the use of installed tests.
