“…Experienced riders anticipate the horse's movements (feed forward mechanism) and compensate for perturbations from the horse (Terada et al, 2006). Contraction of the rider's rectus abdominis muscles in the second half of diagonal stance (Terada et al, 2004) may contribute to the synchronous posterior pelvic pitch and anterior trunk pitch reported here and in other studies (Byström et al, 2015;Münz et al, 2013). In the latter study the riders' upper body became more anteriorly rotated relative to the pelvis as trotting speed increased, which may be a learned response to accommodate the effects of increasing speed.…”

“…The magnitude and orientation of the velocity vector of the horse's trunk affect the rider's trunk and head position. Pelvic pitching motion in sitting trot is highly repeatable even in riders of moderate ability and riders with reduced pelvic pitching compensate by using increased pelvic roll (Münz et al, 2013). Thus, riders may use individualised strategies to stabilise their upper body and accommodate perturbations from the horse.…”

The objectives were to compare sagittal plane posture of the pelvis, trunk and head of elite dressage riders when they ride actively to train the horse versus sitting passively and following the horses' movements at trot, and to evaluate the effects of these changes in rider posture on load distribution on the horse's back. Synchronised motion capture and saddle mat data of seven elite dressage riders were used to measure minimal and maximal angles and range of motion (ROM) for the pelvic, trunk and head segments, the angle between pelvis and trunk segments, phase-shift between pitching motions of pelvis and trunk, and pelvic translation relative to the saddle. Non-parametric statistical tests compared variables between the two rider postures. In the passive rider posture the pelvis, trunk and head showed two pitching cycles per stride. Maximal posterior and anterior pelvic rotation occurred, respectively, early and late in the horse's diagonal stance phase. Compared with pelvic movements, trunk movements were slightly delayed and head movements were out-of-phase. In the active rider posture the pelvis and trunk pitched further posteriorly throughout the stride. Most of the riders showed similar sagittal plane movements of the axial body segments but with some notable individual variations.

“…Rising trot is characterised by a temporary loss of contact between the saddle and the rider's pelvis during the rise phase of each stride (Münz et al, 2013). The rider's pelvis is the centre of movement that determines the coordination between upper body and legs and plays the key role in controlling the horse by physically connecting the rider's body weight (via the saddle) with the horse (Münz et al, 2013). Thus, a seat fault in the pelvis may result in a problem somewhere else in the rider's body (Blokhuis et al, 2008).…”

“…A preliminary study of the use of individual inertial motion sensors for rider pelvis kinematics was carried out by Münz et al (2013). They analysed pelvic rotations in the anterior-posterior and lateral axes at walk, rising trot, sitting trot and canter.…”

“…This study reported a greater tendency towards anterior pelvic rotation in the beginner rider group in walk, sitting trot and canter gaits. Eckardt et al (2014) extended the work of Münz et al (2013), using a full-body inertial measurement system (Xsens TM MVN) to capture kinematic data for the head, trunk, pelvis, elbow and knee of the rider during sitting trot. They confirmed both the within-subject repeatability and between-subject variability of the method for a larger sample size (n=10).…”

This is an author-created version of a manuscript accepted for publication in AbstractEquestrian sports report three to five times higher incidence rates for lower back pain than that of the general population, with hip flexion angles of 50-60° suggested as a causal factor. Inertial motion capture technology enables dynamic measurement of rider kinematics but data extraction is time-consuming. The aim of this study was to develop a software tool to automate the process of extracting biomechanical data from the Xsens TM MVN (MoCap) system to investigate postural changes in riders, comparing static position at halt with dynamic position during the sit phase of rising trot. The software was found to be efficient, reducing data extraction time by 97% when used with a sample of 16 riders. Good correlation was found between hip flexion and pelvic anterior-posterior rotation and between halt and trot but with significantly greater values of hip flexion and pelvic anterior rotation in trot. No riders showed hip flexion >50° at halt but 11 riders (69%) showed hip flexion >50° during the sit phase of rising trot, indicating that dynamic assessment is important when considering rider postural faults that may put them at risk of back injury.
