The effect of exercise intensity and use of an electrolyte supplement on plasma electrolyte concentrations in the Standardbred horse

Eleven Standardbred horses were tested to assess plasma electrolyte fluctuations during different intensities of exercise (at rest, immediately following 20 minutes of jogging and immediately following a two-minute race), with and without an orally administered electrolyte supplement two hours prior to sample collection. Exercise treatments were repeated after horses were given an oral dosage of an electrolyte supplement two hours prior to sample collection. Data was analyzed using a repeated incomplete 6 x 6 Latin-square design with a 3 x 2 factorial arrangement of treatments (exercise x supplement). Jogging horses had an elevated heart rate as compared with resting horses and plasma potassium concentrations that were higher than those of the other two treatments (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
