Studies show the importance of biomechanics for horse and rider

Separate work on rider position has had interesting results for all equestrians and their horses

THE importance of rider biomechanics to horse and rider movement and welfare has come into the spotlight with a groundbreaking recent study, and a separate system based on crustacean vision.

Russell MacKechnie-Guire told H&H of his new research projects into the effect of knee block design. In a separate project, Ilse Daly’s work with mantis shrimp led to her setting up Blackdog biomechanics.

Dr. MacKechnie-Guire said his research, accepted for presentation at the British Equine Veterinary Association 2021 congress, shows that knee block design plays a “crucial role” in allowing the rider’s pelvis to stay in the neutral position, which benefits equine movement.

The researchers used threedimensional motion-capture devices under the saddle to record spinal movement; pressure mats under the saddle and rider’s seat; and markers – on the rider to record movement patterns, and on the horse to analyze gait. They compared elite-level dressage riders in a standard block and one with multiple layers, including shock-absorbing material, that allowed the knee more freedom.

They found the restriction caused by the standard block pushed the pelvis back; seat bones moving from the lowest part of the saddle to the rise of the cantle.
