I’ve seen commentary about this video posted on a few online horse forums, but this is the first link I’ve actually been able to get to work. Before I post it, a disclaimer: this is a kind of oogy video. There is blood, and guts, and a deceased racehorse involved.
However… it is pretty darned fascinating and gives some great insight on how a racehorse “works” – and if you’re into veterinary nerding like me, you will be really into it (I was only sorry they didn’t get into the mechanics of the hind end so much, seeing as that’s the “engine” of the horse!).
One of the things they focus on are how the front legs absorb pressure, paying close attention to the soft tissue of the lower leg. They also show what happens if there is a “ding” against those tendons while they are bearing the weight of a full gallop. Another major component of this video is breathing and the equine airway – this part was fascinating to me, mostly because I never fully understood the mechanics of a horse who “flips his palate” until they demonstrated it (along with showing dynamic footage of a horse’s windpipe at a full gallop) with the actual body parts involved.
If you are sensitive to blood, ooginess, or the idea of a necropsy/dissection, I will advise you not to click this. But I had to post it here since some of the things it touches on are things we deal with on a regular basis – things like breathing problems, for example. Plus it’s just plain fascinating. The horse’s lungs, for example, are a masterpiece. Just amazing!
