Re: [RC] Resting HR on young horses - Truman Prevatt

From all I have been able to find out - including input from some very experienced vets one difference between humans and horses is conditioning doesn't significantly impact the resting heart rate in horses while it does in humans. The resting heart rate is closely associated with "stroke volume" the higher the stroke volume the lower the resting rate. It seems the stroke volume is genetically programmed and fixed in horses.

I have ridden primarily two horses for my miles. I am also fairly familiar with my wife's horse. My mare has a resting rate of 26. She is a walking horse. The Jbird - an Arab - has a resting rate of 34. The mare in her prime would eaisly out recover the Jbird in his prime. Same conditioning. She would drop like a rock to 52. His first plateau is about 60 - which interestingly enough is the difference in their resting rates.

My wife's horse - an Arab - has a resting rate of about 30. He easily out recovers the Jbird - even with the Jbird being in a lot better shape.

These are two rat results and a lot of people claim resting rates don't matter - however, all other things being equal I'd pick a horse with a lower resting rate than a higher resting rate as an endurance prospect.

Interesting enough the mare's two offspring that we still have both have resting rates of about 26. One broke his leg at 5 weeks old so he's not an endurance horse but a nice trail horse. The other one we are just starting to ride.

How much does a horse's heart rate change with conditioning? Is the resting HR of an unconditioned 3 year old the same as what it will be as it ages and is conditioned for endurance?
