The objectives of this study were to measure forces and pressure profiles when riding with a conventional saddle compared to bareback riding. An electronic pressure mat was used to compare contact area, mean total force and pressure variables for one rider riding seven horses at sitting trot with a conventional saddle or bareback. The use of a saddle was associated with a larger contact area and higher mean total force compared with the bareback condition. Mass normalized mean total force for bareback riding was lower than expected based on the rider’s body mass, suggesting that shear forces exerted by the rider’s thighs were not being registered by the pressure mat. In spite of the lower total force, the bareback condition was associated with higher average pressure, higher maximal pressure and larger area with mean pressure >11kPa. Focal pressure concentrations were present beneath the rider’s ischial tuberosities in the area of the horse’s epaxial muscles when riding bareback but not when using a saddle. It was concluded that bareback riding was associated with focal pressure concentrations that may increase the risk of pressure-induced injury to the horse’s epaxial musculature. The findings also emphasized that researchers should remain cognizant of shear forces, which may not be registered by the pressure mat, but may contribute to the effects of riding on the horse’s back.
