A fellow troglodyte in front of the old Independence, Mo. Jackson Co. Courthouse(year 1836), and typical KCMO weather to boot.
Bill Pressey comment last post--helpful! Read closely first two paragraphs! From my class room exercise physiology days, they think--in terms of measurables!
My exercise physiology class at MU Columbia was in 1973, and so I'll be a bit rusty with correct terminology, and, hopefully as accurate as possible given passage of time and more recent developments. In terms of exercise science I am thinking I may as well have studied it in the 1920s as 1970s. Although, I must say, reading the equine exercise physiology text book, in the textbook of the 1970s was already into most of that.
With that, I'm taking it that Pressey states an interesting idea, something I have yet to consider! After transitioning to aerobic metabolism at some point out of the gate--a minute or less depending on fitness--the horse hits an aerobic cruising speed (am thinking its a combo of aerobic and anaerobic most of the way) but then, at the speed up, the horse has to transition back to mostly anaerobic. the longer the horse can stave off this transition, the stronger down the stretch. Unknown if that is exactly Pressey's point, but, thinking so. He then attempts to measure this sort of fitness with the heart rate. Give this a hmmmm... for now for deeper consideration!!! Have yet to think of it this way, but very interesting concept!!!

I'm blogging on the fly. What is this about, this performance? What comes to mind.
Winning--difference between winning and losing. Causation!
Speed as the #1.
How to get speed in the horse?
How to get speed over distance?
Leave it there for today.
Training:
4/23 light riderless pasture romp on a still sore hoof. Got the short full speed burst we needed.
4/24: get there to get on and horse limping more severely than day before. Further digging into the sole reveals larger abscess than supposed--it runs all along outside of hoof toe to quarter. Of course it's raining around here. New vet supplies arrived. Will see. As it's lingering, experience is that I'll have to get very aggressive to get rid of it.

Hi again RR, thanks for the thoughts. All energy in a race is a combination of aerobic/anerobic processes, the stronger the aerobic pathways - the less reliant on anaerobic means, and the less fatigue to deal with.
Exercise heart rate moves in lockstep with gallop speed at intensities of 50-85%. Therefore, 90% of provided energy is aerobic in nature in this range.
Stakes winners can gallop faster than a 2min lick, let's say at 14sec/furlong pace, with 90%+ of the fuel from aerobic means, wow. Claimers on the other hand, can only do so at 17sec/furlong speeds - quite a difference and a very convenient way to objectively define aerobic fitness/stamina.
Anerobically, I use HR recovery after breeze exercise to quantify fitness in the absence of oxygen.
A stakes winner can breeze 6F in 1:12 and repay that oxygen debt by showing HR recovery to 120bpm 2min after crossing the wire, during the gallop out. A claimer can only do so after a 4F breeze in :52.
Meant to add-
HR would be meaningless during a race, as anaerobic metabolism is always a large factor.
HR only quantifies aerobic contributions to exercise, and therefore is of best use during submaximal training gallops and/or AFTER fast works.
