The horse-horse-surface dynamic is influenced by the functional properties of equestrian surfaces, with variations in the absorption and dissipation of impact by the reaction forces received by the musculoskeletal system. Thus, the knowledge of the mechanical characteristics of the surfaces can ensure locomotion efficiency, minimize rates of orthopedic injuries, promoting well-being and safety during equestrian athletic activities. Surface performance can be measured by in situ measuring devices, which simulate in part or completely the vertical and horizontal forces generated by equines, verifying the response of the surface. The control of functional properties is recommended by the FEI (Federation Equestre Internationale), because the behavior of the surface directly influences equine biomechanics.
