Nutrition Reboot, Pt. II: Oxygen Optional

Alas, no credible reports have been filed on the location of eventer79-brain.  Even her horses are beginning to show suspicion.  However, Amy's comment on Tuesday's post provided the perfect segue to the next article in the series.  Updated & edited a bit for (hopefully) improvement.

Do. Not. Want.

We were talking about nutrition. And you've been up for days waiting for the secret to growing that unicorn horn (don't lie, own it).

Too bad.

Here's another, equally as important tidbit, though:  different athletic disciplines make different demands on a horse's body. I know, thank you Captain Obvious, right?

Breaking It Down:  The Two Types Of Equine Metabolism

1. Aerobic - the muscles use oxygen while generating energy; a slow process
2. Anaerobic - yes, you guessed it, genius; the muscles generate energy without oxygen; much speedier

Which Is When?

A horse working in a long, steady fashion (think endurance racing or your dressage school) creates energy aerobically.  Fat, the horse's go-to fuel, requires oxygen to complete the conversion to horsepower (just like your fireplace must have a flow of oxygen to burn up your firewood & create heat).  He has an advantage:  this is a much easier & longer-lasting method of energy production.

However, if Dobbin has to work hard & fast (think sprinting or jumping), he cannot get oxygen into his body & burn fat fast enough to meet his increased energy demands.  So his muscles turn to glycogen stores (a carbohydrate stored in the liver & muscles that the body can convert to glucose [muscle fuel]), which can be burned anaerobically.

Life Is Full Of Trade-offs

To complicate matters, glycogen is a finite resource & stores are much smaller than his fat supply.  Burning it also produces lactic acid, which fatigues muscles.  So, you, as pilot, want to save those precious reserves until you really really need it.  Save that hard sprint or gallop for your horse trial or other vital moment.  And once burned, you MUST to take time to replenish the storehouse before you ask again.  

ALL TEH SCIENCE!!

If he gets really desperate, Dobbin can also turn to blood glucose for energy.  This is a critical resource for nervous system function, though, & there isn't much of it (about 1% of the body's fuel supply), so we don't really want to push him this far.

Is your brain fried by science-geekness yet? I could go into ATP & muscle cell pH, so be grateful...

Why Should We Care About All This?

Knowledge is ALWAYS power when it comes to horse management.   If I understand what my horse's body needs to do his job & how it uses what I give him, I am better able to meet those needs & maximize his performance safely.

In addition, understanding all of that helps to understand this, the point of action: the more fit your horse is, the better he is able to utilize his fat stores first.  The unfit horse may have to get up to 40% of his energy from his glycogen reserves during even light exercise.  With conditioning, he can drop that percentage dramatically even during moderate exercise, giving you both more time under saddle & reducing the chances of equine metabolic distress.

So What's The Plan?

Do we then stuff our horses full of lard?  How do we refill his glycogen tanks?  Those answers are up next, along with a brand new addition to the series:  why choosy 'moms' choose...uh...their feed very carefully.

Throwback...Tuesday: Rocket Fuel & Other Stories

A brain belonging to eventer79 has left the building.  If found, please return to your nearest Missing Blogger Station immediately.  

To fill the static-y void in the meantime, I have brushed the dust off our miniseries on equine nutrition (which you can access in full under the handy Education menu) for new readers.  Ummm, new as in "what, you haven't been reading my riveting brain-dribbles for the past four years straight?!"  

---

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, BFF, 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 & drown. I always held equal skepticism for both. Turns out, I was partly justified.

Wait, So I Will Not Kill My Horse By Riding Him After Dinner?

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).

Psh, can eat AND work...

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 & then put Dobbin away before he has to switch over from fat metabolism. What you want to try to avoid, for maximum energy accessibility & efficiency, is hitting it right on that two hour mark, when insulin levels are highest & 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 & a handy bit of info you can toss out if someone gives you crap for riding your horse right after he ate.

Scorecard: Science, 1, Anecdotes, 0!

Well, unless he gets a better offer... 

Solo: No worries, big little bro, nap on, I'll stand guard.

Meh, screw that, the sun feels good.  You're on your own.

Just Another Day With Dr. Bob

Yep, Encore decided a whole month was far too long to be separated from Dr. Bob.  Despite the terror-inducing zombie cows that live at the vet clinic (so Encore says).

While Encore was getting stronger, his feet are healing, & he did fairly well in our lesson, I still felt I might be missing something.  It's that little feeling you can't quite put your finger on.  And since you are a horse owner, the obvious solution is to throw money at it! 

Encore's Kent & Masters - love!

Looking at him from the ground, I could see the tightness in his hind end.  I also checked the fit of his dressage saddle after our lesson & noticed that I needed to narrow it a bit until his topline redeveloped.  Which explained the knots behind his withers I'd been massaging, as the panels were pressing down in the front.  He was also getting quite crabby about picking up his right lead. 

I always expect some muscle soreness bringing a horse back into work & rebuilding muscle.  However, there was just enough weight on the "I just want peace of mind" side of the fence to push me over & make me hook up the trailer.

I Don't Call Him Batman For Nothing

It was worth the trip.  And while paying vet bills is never any fun, there is no such thing as a Dr. Bob visit where you don't learn ten things & get lots of good stories!

What do you mean I have FOUR legs??!

My hypothesis was, for once, pretty accurate.  Dr. Bob confirmed that the saddle was indeed collapsing a bit up front behind his shoulders.  Encore got his withers & shoulders adjusted back into place with much relief.

He also had a very sore muscle bruise on the lower half of his left hindquarter, a likely result of an incident BFF reported when I was traveling for work:  Encore had an idiot moment galloping across his paddock, once again forgot he had back feet, slipped, & fell hard on his left side. 

She said he hopped back up, she checked him over thoroughly & walked him out, and I checked him out when I got home.  We found no evidence of injury & he was moving evenly.  He's not exactly in heavy work these days either!

It's Going To Be Ok...Today

Dr. Bob showed me how to feel out the spot in the muscle where he said there was probably just some fiber separation that was healing.  I'm just to massage in the Majykal Butacore Creme Of Awesome & keep him moving as he finishes out recovery.

Our farm pond is zen

Overall, good news, some minor tweaks, and the plan & peace of mind I was looking for!  His feet & shoes got the thumbs up, so we can keep moving creeping forward.  Which I was thrilled to hear just as the gorgeous fall weather has begun!

All I Need Is Time

Who needs a bank balance anyway??  For now, Encore will just have to think up something new, since this one didn't get him out of work.  In the meantime, he gets to enjoy medicated ass massages while I schedule the saddle fitter for some wool adjustment & dig through the couch cushions for $1200 to stock our winter hay!  0.0

Today, though, the grass is still green & the air is crisp & perfect, making it worth every bit as I can hear the satisfied nomming of two happy horses floating through the open windows.  I think I might have earned a nap after dragging pastures & detailing horses this morning...

The best kind of sunset has horses in it

Drive-By David Lesson Report!

Owning it in July

If I haven’t mentioned it yet, I have THE BEST NEIGHBOURS EVER!  Behind me lives a wonderful professional trainer who rode her now-retired Appy at Prelim/1*/CCN in the late 1990's/early 2000's; back when I was still a spectator, eventing was Eventing with a full endurance day, and they ran all the classic events like Radnor & Ledyard & Bromont.  As she has an all-weather arena, jump field, & hosts a variety of clinics & practitioners in addition to her own lessons, I walked over after our last David date (erm, I totally meant to post Encore’s videos for that one) with a big question.

Skipping through some cat-herding to the exciting result: we collected some of her clients & a few of my fellow David-disciples and I was able to have my lesson…IN MY OWN BACKYARD!  In some odd fantasy world with no trailer-packing, no driving, I could just saddle my horse & ride up the fenceline to enjoy my Circle of Death.  The word gratitude doesn’t even describe it, given how much I need good things in my life right now!

The Jumping Dressage Lesson

Despite my plans of improving on our jump performance in July, Encore had only been back in work for two weeks & still lacked hind strength, so I opted to put on the dressage saddle.  I wanted David’s eyes to evaluate my horse once again. 

Not Hackney trot anymore!

Perhaps the most rewarding part of our initial warmup (aside from the words, “He looks pretty good to me!”) was that the Circle of Death now includes less Death!  Due to my own exhaustion, humid days prior, & a horse who’d been standing around on duct tape for six weeks, much of our schooling had been at the walk & trot.  However, I had focused hard on fine-tuning & brushing the dust off of one concept:  You Will Move Off My Inside Leg & Accept My Outside Rein. 

Hello, payoff.  Imagine that:  break it down to simple, clear things, teach your horse to respond to individual aids, and *gasp* I didn’t have to work so hard to get a response to my aids!  Erm, some of us are slower learner than others…  *raises hand*



My lessons are so rare, they are incredibly valuable to me.  While forward energy is crucial, David reminds me each time we meet how important it is for this horse to unlock his body & open his topline FIRST.  Encore must be correct & balanced before he is asked to move out, otherwise you end up back at downhill rushing.

Ok, I Couldn't Help Jumping A Little...

I knew his butt would tire soon, but we decided to do some simple jump work at the end, for the sake of my rusty self.  I confess, hearing “keep his poll up & wait with your body” STILL after five years makes me beat my head on the table a little.  Perhaps you can even hear me mumble, “I should get a tattoo of that” in the video, ha.  I have to wonder if David gets tired of saying it…





While Encore was compensating a bit at the end, it was good for both of us to feel some balance & pace again.  Watching the videos, I realize that I lapse into riding him like he is still a green horse!  Although our three years have been rather a roller coaster, I need to remember that I have actually trained him along the way and he now has a skillset of his own.  Fortunately, I have no control issues whatsoever, ahem, none at all…  *shifty eyes*

The Big Takeaway

I do consider Encore a Training horse now, but this reinforced for me yet again how vital it is to stay focused on the core principles – effective aids, consistent rhythm, balance for you & your horse, enforcing & rewarding correctness in your horse – no matter what your level or discipline.  Riding can seem overwhelmingly complicated sometimes, in a world full of books & articles & forums & clinics, which makes me appreciate David’s focus on methodical simplicity even more.  It’s the perfect antidote for my crazy hamster brain.  My horses have no idea how much gratitude they owe that man for that!! 

Chill, mom, I got skillz
