Scientific Research Publications

In line with Centaur Biomechanics’ research strategy, Dr. Russell MacKechnie-Guire has an extensive research portfolio with publication of more than 50 research items. In collaboration with world-renowned researchers, using state of the art measing systems and scientifically robust protocols, Dr. MacKechnie-Guire has been involved with, and led multiple studies quantifying:

  • The effect that girth, bridle and saddle fit, and saddle design has on the locomotor apparatus of the horse
  • The effect that the rider has on equine locomotion
  • The effect that various pieces of equipment, when used for training and rehabilitation, have on the horse 
  • The effect that the rider has on equine back movement

 

Centaur Biomechanics’ mission is to carry out research which can be applied and used to improve equine health, welfare, soundness and performance across the globe. We have multiple projects currently underway.
