SELECTED BLOOD PARAMETERS DURING RECOVERY FROM STRENUOUS RUNNING EXERTION IN TROTTERS

During training, in 10 trotters, blood samples from the vena jugularis were taken before and after a heat with 80% of maximum capability as well as in the recovery period. Lactic acid concentration and pH-value , haematocrit and haemoglobin content, as well as protein concentratio n and osmolality were measured. With the exception of protein concentr ation, the dme course of the values during the recovery could be descr ibed by simple mathematical models (biexponential or exponential equat ions). Only in the case of blood lactate concentration, the basal valu e was not yet achieved 120 min after the end of exercise. In the case of the other examined parameters, the homeostasis aas restored earlier . Therefore, it seems to be recommendable when performing tests with p reliminary heats and finals on the same day to stick to a break of at least 2 h between two races.
