Science of the Olympics: Sport Analysis Videos to Inspire Your Thoughts on Horses


Note: NBC Olympics videos have an annoying auto-play function so the videos have been moved off the blog. Please go to "Science of the Summer Olympics: Engineering In Sports", a 10-part video series produced in partnership with NBC Learn to view the videos described in this blog post.

Have you been staring at a television screen, immersed in the Olympics? Are you chewing your nails for the Swiss beach volleyball team or the Luxembourg table tennis team? Do you wonder if they ever really will get back to Greenwich Park and the equestrian events?

We get wrapped up in the competition of sports but the Olympics is a good time to remember that the same sport science that is used to advance horse sports and hoof science is also used on human athletes.

So whether you are Usain Bolt or Zenyatta, there's a professor at MIT who can dissect your stride. And the same terminology is used whether you're measuring the stride of a track star or a Thoroughbred.
   
How can we get BMW interested in horses? In order to maximize his performance in the decathalon, 2008 Olympic gold medalist Bryan Clay teamed up with engineers from BMW to improve measurement of the horizontal and vertical velocities of his long jumps.

Could the same long-jump technique be used to analyze how Kauto Star won the Cheltenham Gold Cup or how a rider like Meredith Michaels-Beerbaum's horse will clear the water jump at Greenwich Park this weekend?

While you're watching the Olympics, think about the fact that the emerging gait analysis and sport science we see used in horse sports is being applied to each and every one of those Olympic sports. In some aspects, horse sports have lead the way. In other aspects, horse sports have a lot of catching up to do.

So don't think for a minute that you're wasting time watching the Olympics. You're doing your homework, albeit on the subconscious level in many instances. Some creative thoughts about how horses move are sure to pop into your head a week or two from now, and you'll wonder where those thoughts originated.

Maybe you'll never see a horse on a balance beam, but when you think about the pressure to always improve the level of performance while not crossing the line to injury, you realize that all athletes have a lot in common, whether they're horse or human.

These two sample videos are part of "Science of the Summer Olympics: Engineering In Sports", a 10-part video series produced in partnership with NBC Learn. (You can watch them all online and if you're really interested or if you know a teacher who might be, there are lesson plans available to use these videos in the classroom. Just pretend the humans are horses.)

Calgary Stampede Farriers: Potluck Forging Class Showcases the "Art" of Shoeing Horses (And Why That Matters)


People throw around the term "the art and science of farriery" a lot. What does that mean?

Professional hoofcare requires that the farrier use both sides of his or her brain. While they have to learn the anatomy of the horse and the mechanics of the job, they also have to be able to "right brain" the creation, adjustment or placement of the shoe or appliance being attached to the foot.

I think it goes even further than that, and a good farrier is separated from the pack by the ability to "see" with his or her right brain what the foot should or would look like and understand the left-brain concepts of trimming adjustment and support mechanics required to get it there.

Another aspect is the often unconscious right-brain knowing what the foot will look like in a few weeks or a few months as it grows out from the way it has been trimmed or from the effects of what is being nailed or glued on. It seems obvious that a lot of horses' problems arise not from how the horse is shod initially, but how the foot reacts to that mechanical message over time, especially if a shoe that wasn't ideal on Day One is left on too long.

So there is an "art" to it but sometimes people outside the profession don't see the art in the job, since it is invisible, unspoken and almost impossible to teach or even articulate.

You probably can't measure it, either. No judge in a competition can develop a score sheet for it and you can't design a test for it.

Until, of course, you get a group of farriers together and you hand them simple bars of steel and tell them to make something. Blacksmithing skills tell them how to make something...but what part of their profession is showing them what is inside that piece of steel, wanting to come out?

I think that the "art" side of farriery is something that horses can immediately recognize, and appreciate. Maybe some horses have never experienced it. Maybe, for other horses, it is all they have ever known and they have the soundness to prove it. Still others, the high-end competition horses, depend on the art side of farriery to come to their rescue and keep them going, often after the "science" side has failed.

Stand back: watch the art side take over a group of farriers from around the world at the 2012 Calgary Stampede World Championship. Enjoy the show.

(Note the show has 50 or so photos of the farriers and then it may keep going to other unrelated subjects posted by the Stampede. Sorry about that!)

Equine Sport Science, ESPN-Style, Looks at Zenyatta


During today's Breeders Cup broadcast, ESPN took a stab at trying to explain Zenyatta's superior performance ability. They put together great graphics and computer images but understandably had to take some shortcuts to "dumb it down" for the casual national television audience.

I can just see Professor Hilary Clayton, the leading biomechanics expert in North America, pursing her lips and shaking her head, "Well, noooo, not exactly..." and Professor Jean-Marie Denoix over in France,  rolling his eyes, throwing up his hands and sighing, "Oh, mon dieu! The Americans just don't understand..."

How do you squash a PhD into three minutes? Well, you don't. But at least they tried.

Of course ESPN can't go into detail--John Brenkus only had three minutes to explain the whole thing! Anyone who knows about horses will know that it's not just about stride length and height at the withers--if it was, the big horses would dominate, and we'd have no way to explain Goldikova, Smarty Jones, Northern Dancer, Mine That Bird (he did win the Derby!) and all the smaller, more compact Thoroughbreds who are, after all, the more common horses running in our races. And the more commonly found horses in the winner's circle are not over 17 hands.

The same is true of jumpers; it might seem like bigger horses would be better jumpers but it's not a given. There are many factors to consider.

The great 18th century racehorse champion Eclipse is believed to have excelled because he was extraordinarily "normal". His body parts were in harmonious proportion to each other, which scientists believe facilitated speed.
Studies have been done that show that the most successful racehorses are not the largest or the smallest or the most anything but the most "average"--the ones whose proportions are average. Take Eclipse, for instance. That most successful of original racehorses left us his skeleton, which has been analyzed by Professor Alan Wilson and his researchers at the Structure and Motion Analysis Lab at the Royal Veterinary College in England.

Based on Eclipse and other racehorses, Wilson's data analysis determined that it was not size that mattered in  champion racehorses but proportion. The champion racehorses like Eclipse had all their body parts in proportion to each other--no one body part was out of a statistical range in proportion to others. Their skeletal systems demonstrated a balance of dimensions.

(By the way, the great Eclipse went down in history in the 1700s for winning 18 races--one less than Zenyatta. It is said his jockey never used a whip or spurs.)

The formula for speed is not just the distance covered in a stride, but the stride length x the stride frequency. There is also the x factor of efficiency--how straight are the limbs, how much excess motion is there, how efficient is the respiration, etc.?  How easy is it for the horse to reach his hind limbs underneath his body, and how far under his body do they reach? There are many ingredients to a racehorse's stride and speed formula.

So a horse with a shorter stride but a fleeter, more efficient turn of foot can potentially run faster than a long-striding large horse, although one wonders if the smaller horse may tire sooner if taking more breaths and more strides. But they may be more efficient strides.

This is where shoes come in. A horse that can't "get hold" of the track loses stride efficiency and, often, even stride frequency if the foot is delayed in breakover or the horse struggles to re-orient the foot to land in a certain pattern to avoid pain or limb interference or simple fatigue from sinking too deep into sandy footing.

It's probably harder and more time-consuming to train a huge huge with a huge stride like Zenyatta's, and the racing public should remember and respect that John Sherriffs opted to delay her start in the races until she was ready, probably because of her need to finish developing physically and no doubt "find her balance" when running at speed. Most big horses would not be given that luxury to develop first, race when ready.


Those are just some of the factors that enter into the equation of why Zenyatta excels. You can do formulas and analyze her all day but there are some intangibles. One them is called "heart". Not the heart in the chest, but the heart in the spirit. Zenyatta is loaded with that.

We saw that heart today.

A great racehorse will always be just out of the reach of science. If not, there'd be no reason to go to the races. Handicapping would be an exact science. But thankfully we still have that x factor.

Jerry Black DVM Will Leave Pioneer Equine Hospital for Colorado State University Equine Science Program Role

Hoofcare and Lameness has learned that Jerry Black DVM, co-founder of Pioneer Equine Hospital in Oakdale, California, will leave veterinary practice at the end of June to pursue a new role in the horse industry as Equine Science Program Undergraduate Director at Colorado State University in Fort Collins, Colorado. Dr. Black founded Pioneer Equine Hospital in 1973 and built it into one of the leading veterinary hospitals in North America.

A statement sent today by Pioneer Equine Hospital on behalf of the hospital "family" read, "We wish him great success and want him to know that he will always be a part of our family here in California. "

Dr. Black brings unique qualities to his new role at CSU. In addition to his experience as a veterinarian who specializes in performance horse lameness, Dr. Black has been a leading breeder and exhibitor of cutting horses, and owner of Valley Oak Ranch, a stallion station and breeding farm in California. He is past president of the American Association of Equine Practitioners, is currently a member of the board of trustees of the American Horse Council, and has had many horse and veterinary industry roles.

Dr. Black earned his veterinary degree at Colorado State University. The "equine science" program at CSU includes the reproductive and orthopedic research laboratories, among other units, and grants degrees to both undergraduate and graduate students.
