The first Saturday in May is the time for The Kentucky Derby. This year, my family and I will be fulfilling a bucket list item by attending “The Run for the Roses" in person. Watching the various 3 year old thoroughbreds in the prep races leading up to The Derby, and how beautifully and athletically they perform, it led to wondering just how horses compare to humans in terms of locomotion. It was always fun to talk to farrier (work on hooves) friends about how they work with their “patients” compared to how I would manage the biomechanical needs of my patients. I even came across a textbook at a podiatric conference once titled “Equine Podiatry”. Since KevinRoot Medical is a tech based company, I asked ChatGPT to compare human gait to equestrian gait, and this is what it came up with.

Comparing human gait to equestrian (horse) gait is an interesting biomechanical and rhythmic exercise. Though both are forms of locomotion, they differ fundamentally due to anatomy, limb configuration, and evolutionary purpose. Here's a breakdown:

1. Basic Structure

2. Types of Gait

Human Gaits

• Walk: Alternating steps with one foot always in contact with the ground.
• Run: Both feet leave the ground during a stride (aerial phase).
• Jog/Sprint: Variations of running with speed and stride changes.
• Skipping/Hopping: Complex, often asymmetrical or aerial patterns.

Horse Gaits (natural and trained)

• Walk: 4-beat gait (each foot hits the ground independently).
• Trot: 2-beat diagonal gait (diagonal pairs move together).
• Canter: 3-beat gait with a leading leg.
• Gallop: 4-beat fast gait with a suspension (aerial) phase.
• Pace (in some breeds): 2-beat lateral gait.

3. Biomechanical Comparison

4. Rhythmic & Neural Control

• Humans rely heavily on conscious balance and coordination, especially due to upright posture.
• Horses rely more on reflexive and rhythmic neural patterns (central pattern generators) and proprioception for gait transitions.

5. Evolutionary Purpose

• Humans evolved for endurance walking and running—efficient for persistence hunting and long-distance travel.
• Horses evolved for burst speed and long-distance locomotion across open plains, with powerful legs and efficient gaits for escaping predators.

I will admit to not completely understanding all of this, especially the graphic of the human and the horse. It is interesting to note that humans have adapted as predators (hunters) and horses as prey animals. FYI, I am betting on a gray named “Sandman” for the win, good luck!
