Re: [RC] Beta Blockers - Lynn Kinsky

Based on my response as a human, beta blockers can also slow the heart sufficiently to impact cooling (one reason the heart rate is up in the first place). I fainted off the horse a couple times while riding in the heat (from heat exhaustion while on a beta blocker for high blood pressure) and have refused beta blockers ever since. -- LK

Tom, there was a study done at the Department of Veterinary Clinical Sciences, College of Veterinary Medicine, The Ohio State University about beta blockers and glucose utilization. I only looked at it briefly but it appears that slowing the heart rate didn't help endurance. I think they felt it demotivated the horse.?You can read the study at: http://jap.physiology.org/cgi/content/full/89/3/1086.
