[ Birds chirping ] If you want to understand just why horses are so fast, Kentucky is a good place to start.
David Lambert has spent a lifetime studying the thoroughbred, breaking down the physics and chemistry of a running horse.
I've pulled David away from his work to help me understand, with the help of a special, slow-motion camera.
There we go. So we'll be able to see the footage on this monitor as the horse runs by.
LAMBERT: Perfect. Yeah. Let's do it.
[ Hooves thudding ] THOMPSON: Hoh! -LAMBERT: [Laughing] THOMPSON: Honestly, all I see is a blur LAMBERT: Yes. Yes. -THOMPSON: of moving parts as he goes past.
If we take that run-past and slow it down a little bit, tell me what you're seeing there in the body.
LAMBERT: So let's look as he puts his foot onto the ground, right there, and, now, he's loading that tendon and that ligament, and it's bouncing and throwing the leg forward.
That leg's being thrown by elastic, stored energy, not by muscle.
And it's like a catapult.
The size of the forces just throw those bones out there and back again and onto the next stride.
THOMPSON: So that's very efficient, when those elastics give the energy back to the horse. -LAMBERT: Yes.
Yes, without that elastic energy, he'd have to have legs which were 100 pounds in weight, just in muscle, to move his big body.
[ Suspenseful music plays ] We're dealing here with a very heavy animal.
1,000 pounds, 1,100, 1,200 pounds.
[ Snorts ] As that weight descends, it loads up all the soft tissues in that limb.
The load is suddenly released and, then, the leg is simply propelled out into space, driven by stored, elastic energy.
It's happening all over the horse's body: along his back, on his hind legs.
When he gets going, he's going so fast and there is so much stored energy, it reaches a point where it's beyond control.
♪♪ ♪♪ When you compare him to all the other mammalian species, he kind of stands alone, in terms of his size and his speed.
He's out there on a little pinnacle all on his own.
♪♪ THOMPSON: You know, I've noticed one thing: When we're listening to the training horses as they go past, you hear this enormous breath, every stride.
It sounds like they're struggling for breath.
LAMBERT: Their stride is linked, one-to-one, to their breathing.
When the horse runs, he must breathe out when his front legs hit the ground and he can only breathe in when he's up in the air.
[ Suspenseful chord strikes ] ♪♪ When run and breathe, we're using our ribs.
He's not doing that.
His ribs are locked closed and when he puts his weight on his front legs like that, the weight and the momentum of his viscera is pushing against the diaphragm and creating like a big piston inside his body, so it pushes the air out -THOMPSON: I see.
LAMBERT: and then, when he comes up in the air, the viscera drop back and it sucks the air in.
So he's a big piston, doing this.
THOMPSON: Front legs down, breathe out.
Up in the air, breathe in.
♪♪ LAMBERT: And that creates certain limitations.
The faster he goes, the less time he's got to breathe.
THOMPSON: It sounds to me like it's not -- It's not like breath holding, but it is like suffocation.
LAMBERT: It would be suffocation for you and I, but, again, the horse is different.
His body has adapted to tolerate this unique situation that allows him to keep going longer than you or I could keep going.

[ Neighing in distance ] [ Whinnying ] SPEAKER: Easy, girl.
THOMPSON: Today, David and Michael are taking three horses out for testing.
He needs these horses to sustain 45 miles an hour for a mile.
That's twice as fast as humans have gone.
[ ] Well done, Alex. Thank you.
My one-acre road.
So they all went all right, didn't they?
[ Grumbling ] Did nothing wrong, did he?
THOMPSON: A hard gallop is punishing.
But it turns out, the cost is even higher than I thought.
[ Neighing ] LAMBERT: When a horse tries to run flat out, he's so big and he's going so fast, so there's a price to pay for that.
The blood gets more and more acidic all the time.
The carbon dioxide in his blood builds up and up and up and up and gets really high.
THOMPSON: These are all things that, when we're running or we're swimming, feel really painful, and tell us to stop, -LAMBERT: Yes, yes, exactly. -THOMPSON: like a brake on our effort. -LAMBERT: Yes, yes, exactly.
And horses switch those brakes off.
[ Neighs, snorts ] It's not altogether surprising that horses should be able to do this because there are other animals.
Seals, when they dive.
He can go down into the water and swim around for a long time without having to breathe.
Essentially, it's the same process.
[ Huffing ] THOMPSON: So when get a pain signal that tells us to stop running, something different happens in a horse.
It begins to metabolize energy without oxygen.
Human do this, but not as well as horses.
LAMBERT: Some of the byproducts of this process are euphoric.
He's feeling positive; he's feeling energized.
Basically, he's high.
So the typical picture that a person would have of a thoroughbred racehorse is that bouncing, lively, snorting animal.
All of that is coming from this euphoria they're feeling, having gone to a level of fatigue that we couldn't even tolerate.
THOMPSON: The physiology of the horse is set up to sacrifice everything for a run. -LAMBERT: Mm-hmm, absolutely.

So you have cooperative predators and cooperative prey.

FEH: They do have a sort of real cooperation.

What the Przewalski horses do in the wild, our own horses do in our fields, if we only let them be themselves.
It's amazing how eager horses are to please.
Without a language in common, that's like mind-reading, an incredible ability that English animal psychologist Karen McComb is trying to understand.
At a riding stable, Karen's researchers are preparing for a day of horse testing.
For Karen, this is science.
But, for the horses, [chuckling] it's play.
McCOMB: I mean, anyone who's worked with horses, they sense this enormous personality that differs from individual to individual.
No one has looked at that it an animal.
We're used to the way humans express emotion, but, actually, horses are making these very subtle facial movements and have an incredibly mobile face and they are expressing emotions as well.
What we really want to do is work out what the emotional life of horses really is, what their emotional world is really like.

But stop. Actually, that sniffing the ground again occurs consistently in response to something that's a so that he's unsure about this.

They have enough understanding to interpret, not only emotion in the faces of their own species, but emotion in faces.
[ Birds chirping ] [ Hooves thudding ] THOMPSON: It makes sense that horses use emotions [ Neighing nearby ] to communicate with each other.
But what fascinates me is they can read emotions as well.
[ Huffing ] McCOMB: They're capable of putting together the sort of representation of the person with the emotion.

But that's not all.
Karen is also interested in another quality: curiosity.

[ Neighing nearby ] We're also trying to see where personality fits into the whole thing.
For example, how bold an individual is, versus shy.
It's these differences, which we also see in humans, that are going to be the stuff of their emotional lives, too.
[ Grumbling ] THOMPSON: With these tests, Karen is able to identify outgoing horses and introverts, just like we see in humans.
Popular horses like to spend time with other horses.
But the horse standing at the edge of the field might prefer human company.
-[Neighing] -[Snorts] McCOMB: Children who don't fit in will turn to their pets, but it's quite interesting [chuckling] that horses that don't quite fit in will also turn to humans.
[ Neighing nearby ] [ Snorting ] And our tests are actually showing that.

[ Snorts ] [ Grumbling ] THOMPSON: How do you know how far to take it and when to stop?
ANDERSON: You know, we're lookin' at the expression in his face, lookin' at that tightness through his neck.
He's tellin' me, 'Jim, you can do more,' or 'Jim, I'm gettin' too worried.
I can't take this.'
So that's where I'm just readin' and lettin' And so, when I can go through this with him not gettin' worried and just no big deal, that's when it's gonna tell me he's ready to saddle.
[ Neighing ] [ Grumbling ] Now, he's gettin' good with the tarp.
THOMPSON: So what are you doin' now, Jim?
