Equipping saddles with adjustable stirrup bars, bringing the leathers farther forward or father backward on the saddle, can help customize the ride for each horse-rider pair, said Pauline Martin, DVM, PhD, of the University of Lyon, the National Veterinary School of Maisons-Alfort, and CWD France-Sellerie saddlery, in Nontron.

Martin and fellow researcher Marie Sapone, MSc, studied the biomechanical effects on two riders using a saddle with adjustable stirrup bars. Each rider rode the same horse at a canter with the stirrups set to three different positions: forward, central, and back. They presented their results, part of their larger Saddle in Motion Project, at the 2017 French Equine Research Day, held earlier this year in Paris.
