Effort of varying intensity as a factor influencing the variability of selected biochemical blood parameters of jumping horses

Abstract

Blood samples were collected from horses in four time points of the spring-winter training season, according to the difference in effort intensity characteristic for each period. Serum contents of glucose, cholesterol, and creatinine, as well as activity of creatine kinase, aspartate and alanine aminotransferases, and alkaline phosphatase were determined. Training did not cause muscle damage, and as a result of training, changes in the characteristics of both, contraction and biochemical properties of muscle tissue took place, which was confirmed by the conducted tests.
