A field study of post-exercise values of blood biochemical constituents in jumping horses: relationship with score, individual and event.
Abstract: The variability of the post-exercise values (PEV) of blood lactate and of some other blood constituents were studied in 8 healthy and fit jumpers through 5 national competitions of equal difficulty. The effects of factors such as the individual, performance and competition on these PEV were analysed. Venous blood was sampled immediately after the 5 show-jumping contests and was analysed for packed cell volume (PCV), blood lactate, blood glucose (GLU), total plasma protein (TPP), bicarbonate (HCO3-), sodium (Na+), potassium (K+), chloride (Cl-), calcium (Ca2+), serum activities of lactate dehydrogenase (LDH), creatine phosphokinase (CPK), glutamic-oxalacetic transminase (GOT) and gamma glutamyl transferase (gamma GT). PEV of these 13 blood parameters were analysed using a fixed linear model which included the effect of horse, score and competition and their respective interactions. The analysis of the influence of each of the 3 fixed variables showed that (1) there was no relationship between the PEV variations and the score; (2) there were significant (P less than 0.05) variations induced by the competition in Na+, Ca2+, TPP, LDH and GLU, and (3) there were significant interindividual variations as regards Ca2+, TPP, CPK, gamma GT and PCV with P less than 0.05, LDH with P less than 0.01 and blood lactate with P less than 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)

This research focuses on examining the changes in blood biochemical constituents in jumping horses after exercise and how they correlate with performance, individual horse, and event. The study finds no direct correlation between these post-exercise values and scores obtained in the competitions, but does find significant variations due to the competition and individual horse.
Objective of the Research
- The principal objective of the research was to investigate the variability of post-exercise values (PEV) of blood lactate and other blood constituents in jumping horses. The factors studied for their effects on these values included the individual horse, performance achieved, and the competition in which they participated.
Methodology
- The study was conducted with eight physically fit and healthy show-jumping horses over five national competitions of equal difficulty.
- The researchers took venous blood samples immediately following these competitions and analyzed their packed cell volume (PCV), blood lactate, blood glucose (GLU), total plasma protein (TPP), bicarbonate (HCO3-), sodium (Na+), potassium (K+), chloride (Cl-), calcium (Ca2+), and serum activities of lactate dehydrogenase (LDH), creatine phosphokinase (CPK), glutamic-oxalacetic transaminase (GOT) and gamma glutamyl transferase (gamma GT).
- These 13 blood parameters, the PEVs, were then analyzed using a fixed linear model, which took into account the effect of the horse, score, and competition along with their respective interactions.
Findings
- The results showed no direct correlation between the variations in PEV and the scores obtained in the competitions.
- However, significant variations were observed due to the type of competition for participants, notably in Na+, Ca2+, TPP, LDH, and GLU with significant differences indicated by a P-value of less than 0.05.
- Moreover, they found significant inter-individual variations for Ca2+, TPP, CPK, gamma GT, and PCV (P less than 0.05), LDH (P less than 0.01), and blood lactate (P less than 0.001). These findings imply that individual differences among horses significantly influence post-exercise blood constituent values.
