So I have been reading about nutrition (the horse's, not mine, who cares about that?). Why? Well, because I don't want to do the actual work I am SUPPOSED to do, so why not. And if it has the word "horse" in it, then it is a pre-ordained given that I must read it. Who am I to argue with those that ordain??
Lots of interesting things to share with you. How horses use their feed, what different types of feed items offer, and what magical food will make your horse grow a unicorn horn (calm down, lifeshighway, one of these items may or may not be fictional).
Those of us who grew up obsessed with horses learned many important horse-keeping rules that have been passed down through generations. One of those things that I always heard was that you never worked your horse hard right after he ate. Much like nagging Aunt Margaret told you never to swim right after you ate or else you'd surely get a cramp and drown. I always held equal skepticism for both. Turns out, I was partly justified.
After your horse eats, his body begins to metabolize his food. This means that his blood insulin will spike, which reduces the efficiency with which the body burns fat (fat is generally the go-to energy resource for horses). So, if they need energy when insulin levels are high, their bodies will instead turn to stored glycogen reserves first. While this is hardly deadly, glycogen is something you want to save until you really need it (I'll explore why in the next post).
So, what's a rider to do? Well, you have two choices. It takes about four hours for that insulin spike to return to baseline. So you can (a) wait four hours (Suck! Who wants to do that?!) or (b) ride immediately. That's right, the spike doesn't really get up there for about two hours, so if you hop on within thirty minutes, you can have your ride and then put Dobbin away before he has to switch over from fat metabolism. What you want to try to avoid is hitting it right on that two hour mark, when insulin levels are highest and burning fat is the most difficult.
Now, obviously, we're not going to get this right every single ride, but it's something to shoot for as a general trend and a handy bit of info you can toss out if someone tries to give you crap for riding your horse right after he ate.
Scorecard: Science, 1, Naysayers, 0!
