Blood parameter and heart rate response to training in Andalusian horses.
A study was performed on Andalusian horses in order to assess the response of heart rate and various blood parameters to training. Two tests were performed, at two and four months of training respectively. Exercise schedules were of increasing intensity, over a distance of 1000 meters. Speed was progressively increased, from 4 m/s to 8.5 m/s, over four exercise stages. In both tests, a recovery period of 5 min followed each stage. Sample collection (by puncture of the external jugular vein) was performed with the animals at rest, within the first minute after each exercise stage, and at 10, 15, 20 and 30 min of final recovery. Samples for analysis contained plasma for measurement of lactate, glucose, ion and creatinine levels. Heart rate was measured using the Polar Sport tester. The most important parameters in both tests proved to be glucose level, heart rate and lactate concentration. Variations in electrolyte and creatinine levels were transitory, normal resting values being regained after 30 minutes' recovery. Response to daily training was most clearly reflected in altered lactate levels and heart rate; recovery improved with increased training which enhanced aerobic capacity and decreased metabolic acidosis.
