Abstract
Simple SummaryLeisure horse riding is a leading branch of the equine industry worldwide, thus, horses are used for pleasure and in riding schools represent a much larger group than sports horses. Nevertheless, still little is known about the physiological demands and the nature of the exercise metabolism in school horses. The exercise capacity in sport horses is routinely monitored using blood tests including hemogram parameters and selected biochemical indicators. This study aimed to measure the physical activity-dependent blood indicators during the leisure type of work in riding schools in order to compare them with endurance and race horses’ effort-dependent profiles. The similarities between school and race horses in a high level of erythrogram parameters after effort as well as between school and endurance horses in a high level of white blood cell count and high activity of creatine phosphokinase after effort were demonstrated. However, the fluctuations in physical activity-dependent blood indicators were lower in school than in professional equine athletes. The exception was the lactic acid profile, which achieved higher values than in endurance horses and lower than in race horses. Limiting the school horses monitoring to only the endurance or racing blood profile may result in the omission of significant changes in hematological and biochemical parameters.Blood testing is one of the most important ways to improve performance, facilitate recovery and monitor the training of endurance and race horses. However, little is known about the physical activity-dependent changes of blood parameters in horses used for pleasure and in riding schools. This study aimed to perform routine blood tests for training monitoring of sport horses in three different horse types of use. Then the values of blood indicators were compared between school, endurance and race horses to find similarities in the physical activity-dependent profile. The study was carried out on 15 endurance, 15 race and 15 school healthy horses who underwent the typical effort for their disciplines. The hemogram parameters, creatine phosphokinase (CPK), aspartate aminotransferase (AST), blood lactate (LAC), and total serum protein (TSP) concentrations were measured using the same protocol and equipment. Measurements of main hematological and biochemical physical activity-dependent parameters were conducted before, immediately after and 30 min after training. In school horses, the physical activity-dependent increase of WBC (40.9%) and CPK (76.4%) was similar to endurance horses, whereas an increase of RBC (19.1%), HGB (18.6%) and HCT (19.4%) were more similar to race horses. The moderate effort-dependent increase of LAC concentration (2775%) was lower than in race horses (7526%) and higher than in endurance horses (390%). Limiting the training or work monitoring assessment of school horses to only the endurance or racing blood profile may result in the omission of significant changes in hematological and biochemical parameters.
Highlights
The clinical examination provided by the medical practitioner and the trainer’s opinion does not always indicate the performance ability of the sportsman
The attention is paid mostly to obtain the values of blood parameters such as red blood cell count (RBC), hemoglobin concentration (HGB), hematocrit (HCT), white blood cell count (WBC), lactate concentration (LAC), total serum protein (TSP) concentration, creatine phosphokinase (CPK) and aspartate aminotransferase (AST) activity to monitor the health status and training progress of the sport horse depending on the discipline [2,3,4]
WBC decreased to the resting value within 30 min after effort (Figure 1A–C)
Summary
The clinical examination provided by the medical practitioner and the trainer’s opinion does not always indicate the performance ability of the sportsman. Blood measurements and advanced exercise tests are routinely used to assess several exercise capacity parameters of the human athlete [1]. In the case of equine athletes, regular blood sampling was confirmed as useful for detecting equine exercise capacity to improve performance, facilitate recovery, and monitor training [1,2,3]. In veterinary medicine, it is especially important because the fast detection of the low performance is altered by the inability to perform the anamnesis with the patient, as it is in human medicine. The attention is paid mostly to obtain the values of blood parameters such as red blood cell count (RBC), hemoglobin concentration (HGB), hematocrit (HCT), white blood cell count (WBC), lactate concentration (LAC), total serum protein (TSP) concentration, creatine phosphokinase (CPK) and aspartate aminotransferase (AST) activity to monitor the health status and training progress of the sport horse depending on the discipline [2,3,4]
