Effect of exercise intensity on plasma prostaglandin concentrations in horses
1995
Exertion has an effect on plasma, serum, and/or urine prostanoid concentrations in many species. We investigated the effect of exercise intensity on plasma prostaglandin concentrations during and after exercise in horses. Six Thoroughbreds completed 4 trials: 3 exercise trials (low-, medium-, and high-speed) and 1 nonexercise (control) trial on a high-speed treadmill. Blood samples were collected from a jugular catheter before, during and after exercise. The PCV and blood lactate, plasma protein, plasma prostacyclin (6-keto-PGF1 alpha), thromboxane B2 (TXB2), and prostaglandin E2 (PGE2) concentrations were measured before, during, and after exercise. Exercise significantly (P = 0.001) increased plasma TXB2 concentration during and after exercise in the low-, medium-, and high-speed trials, although effect of exercise intensity was not detected. Exercise was associated with an increase in PCV and blood lactate and plasma protein concentrations. There was no effect of exercise on plasma 6-keto-PGF1 alpha concentrations; PGE2 was not detected in plasma from any horse in any trial.
