Effect of training on diverse hematologic parameters in Andalusian horses.

Abstract

A study has been made of the variations experienced by the hemogram and blood volume indices in 16 Andalusian horses after carrying out an exercise test of increasing intensity consisting of 3 sequences of 1000 m each, before and after being subjected to a daily exercise programme for two months. Samples were taken by external jugular vein puncture: while at rest, within the first minute of finalizing each exercise stage and at 10 and 15 minutes of recovery. Both the red blood cells and the hematocrit value showed a significant decrease in their mean values after two months training; conversely, the hemoglobin reached higher post-training figures. Similarly, the volume indices increased their mean values with training but no significant changes for total plasma proteins were observed.
