Kinematic analysis has been used to understand performance in many sports, but few objective studies of equestrian technique have been published. The objective was to describe movements of the riderâs torso and arms relative to movements of the horseâs pelvis and shoulder and the position of the bit during trotting. Six experienced female riders rode the same dressage horse at a sitting trot, with rider and horse kinematics collected. The trot is a symmetrical gait, which implies kinematic symmetry between the first and the second halves of the gait. Three trials of a half stride, from left forelimb lift-off to right forelimb lift-off, were analysed for each subject. In all riders, trunk angle was maximal (backward tilt) in early stance, at which time the riderâs hips were closest to and the riderâs shoulders were furthest from the bit. Trunk angle was minimal (forward tilt) at the end of stance when the shoulders were closest to and the hips were furthest from the bit. Range of motion of the riderâs hips and shoulders varied greatly between subjects. Movements of the riderâs shoulder joint and elbow joint were synchronized with the trunk oscillations, so the distance from the riderâs wrist to the horseâs bit changed by only 15 ± 3mm during the stride. It is concluded that the six experienced riders were able to accommodate the motion of the horseâs body while maintaining a consistent contact with the bit by minimizing changes in the distance from the wrist to the bit.
