“…The repeatability of the pressure mat used has already been described at this and other locations, and the high-speed motion capture technique has previously been shown to be repeatable (De Cocq et al, 2006;Murray et al, 2013Murray et al, , 2015Murray et al, , 2017.…”

“…There is increasing recognition of the importance of horsesaddle interaction (De Cocq et al, 2004;Dyson, 2013, 2015;Meschan et al, 2007;Murray et al, 2017;Von Peinen et al, 2010). Alterations in the pressure pattern under the saddle during different gaits, and peak pressure under the saddle at thoracic vertebrae 10-13 (T10-13) at trot has been related to limb kinematics (Fruehwirth et al, 2004;Murray et al, 2015). It therefore seems likely that specific pressure patterns and magnitude may occur between saddle and horse at take-off for a jump.…”

There is little information about horse-saddle interaction at take-off for a fence, although there is potential that this could have an influence on performance. It was hypothesised that (1) maximum peak pressure under the saddle would occur in the phase of maximum thoracolumbar flexion prior to hindlimb take-off; and (2) limb and trunk kinematics at take-off over the fence would be affected by reducing peak pressure at Thoracic vertebrae (T)10-13 at the point in the stride where peak pressures occur. The peak pressures under the usual saddle (Saddle S) and a saddle modified to reduce peak pressures at T10-13 (Saddle F) were measured during approach and take-off over a 1.30 m upright fence in 12 elite jumping horses. The timing of peak pressures was determined by comparison with simultaneous video data. Shoulder, carpal flexion angle and trunk angle to the horizontal at hindlimb take-off, take-off distance from the fence and fetlock height above the fence were determined using high speed motion analysis. Peak pressures under the saddle at T10-13 and kinematic data were compared between Saddles S and F. Maximum peak pressures occurred at forelimb vertical, during hindlimb protraction, consistent with thoracolumbar ventroflexion. Saddle F was associated with significantly lower peak pressures at T10-13, greater shoulder and carpal flexion, a steeper trunk angle, and higher fetlock height above the fence than Saddle S. Forelimb take-off distance from the fence was not different between saddles, but hindlimbs were significantly closer to the fence with Saddle F, indicating potential increase in ventroflexion through the thoracolumbosacral region. These findings suggest that reducing peak pressures under the saddle at T10-13 are associated with altered kinematics during the approach and take-off over a fence, which may have a positive effect on jumping performance.

“…Marker locations were identified by manual palpation of anatomical landmarks identifying joint centres and segment ends; once located, white skin paint was used to mark each reference point. Markers were located (1) scapular spine, (2) head of humerus (cranial), (3) lateral condyle of humerus, (4) lateral metacarpal condyles, (5) distal aspect of the metacarpus over the lateral collateral ligament of the metacarpophalangeal joint, (6) origin of the lateral collateral ligament (LCL) of the distal interphalangeal joint, (7) tuber sacrale, (8) greater trochanter of the femur, (9) lateral condyle of the femur, (10) talus, (11)…”
