This animated gif was made by synching a series of still images photographed by Eadweard Muybridge in 1887. He made the originals by using a series of cameras and string-triggers. Muybridge made the photographs at the request and backing of Leland Stanford, a race-horse breeder who thought photography could answer the question that had divided riders, trainers, and even artists for centuries: “Do a horse’s feet ever leave the ground all at once during a gallop?” It took Muybridge six years to find a method that would give a definitive answer — and the evidence was considered so conclusive it was even published in the journal Scientific American.
Citation: The original photographs were published in his Human and Animal Locomotion series, (plate 626, thoroughbred bay mare “Annie G.” galloping), published by the University of Pennsylvania.

Here’s another animation from Muybridge’s series of high-speed photographs, also published in 1887 (full citation below). This time it shows a pace. One of the more intriguing things to notice is the rider’s leg, back, arm, shoulder, and head, which remain remarkably steady. Also notice the rhythmic way the horse’s mane moves. It flares up and backwards, then lies down, then flares up again. The still sequence below this section allows you to correlate movement of the horse’s mane with how its legs are moving. Look and see if you can spot a connection that tells you why the mane moves in this particular rhythm. What might it suggest about the biomechanics of the horse’s pacing gait? This is the type of thing you’ll learn in “The Science of Riding with Feel: Horse Biomechanics and You.” Its sections on gait explain the correlation between mane and feet you see here. Those passages and others in the Workbook then help you understand how to apply that understanding of gait to riding with a better sense of feel.
By the way, these animated gifs demonstrate why we plan to put supplemental materials online for free access. Moving images that are clearly explained, and that are also correlated to still images and other kinds of data, enhance everyone’s understanding and enjoyment of horse biomechanics. And that’s our primary goal, to make it possible for every horseperson to learn the things about horse biomechanics they’ve been telling us they want and need to know.
