Studies with horses indicated that the responses of blood biochemical parameters to different exercises vary. Some study also indicated that significant individual variance exist in blood parameters, which makes difficult to detect treatment effect. Therefore, the aim of this study was to examine the correlation between plasma biochemical parameters of show jumpers before and after of high level aqua training and jumping course completion, and the effect of using baseline level as a covariate on the significance of horse effect. Four normally trained show jumpers ageing from 6 to 11 years were trained with high-intensity aqua treadmill in three periods during three days and after they did compete in the Indoor Show Jumping Championship. Blood samples were taken before and immediately after aqua treadmill training program and both days of the competition before and immediately after the course. From the blood plasma samples lactate, lactate dehidrogenase (LDH), creatine kinase (CK), aspartate amino transferase (AST/GOT), glucose, cholesterol, triglyceride, total-bilirubin and cortisol level were determined. Aqua training did result significant changes only in glucose, trygliceride and cortisol level. In contrast show jumping resulted significantly higher levels in all parameters measured except GOT. We found positive correlation between same blood parameters before and after exercise and competition in bilirubin, cholesterol, LDH, GOT, CK and cortisol. Our result clearly demonstrate that using baseline variables as covariate eliminates the significant individual effect. In conclusion when evaluating fitness of horses the type of exercise should be considered and biochemical values measured at rest should be used as covariate factor. Source

Aqua treadmill is mainly used for rehabilitation purposes, but research indicates that this equipment could be used for training as well. The few studies performed with aqua treadmill mainly followed lactate and heart rate changes. Therefore, the aim of this study was to test the effect of high water treadmill training on several blood parameters and on the correlations between them. Eight similarly trained Standardbred show jumper horse competing at the same level were selected with age between 6 to 11 years. The horses were subjected to a one week standardized exercise test which included normal training, training with show jumping and aqua treadmill training. The aqua treadmill training consisted of a 10 min walk (filling up, 4.5 km/h), 30 min trot (13 km/h) and 4 min walk (emptying, 4.5 km/h). Blood samples were taken from the jugular vein before aqua training, at the completion of each work bout, after drying and after one and two hour rest. Blood plasma were separated and lactate, LDH, CK, AST, glucose, cholesterol, triglyceride, total-bilirubin and cortisol level were determined. In conclusion plasma lactate response itself does not reflect correctly the intensity of workload in high water level aqua training, therefore measurement of several blood parameters is advisable. Further studies needed to understand the relationship of metabolic processes altered due to the effect of partial water submersion. Source
