Most techniques are taught in the Weekend Seminar, however Advanced 5-Day Techniques are marked with a *. ![]() Now it’s time to look at Masterson Method Techniques that work well for jumpers. This reverses the rotation of the body axis and allows the hind legs to step under the body to canter on. As the forefeet touch the ground after the jump, they push the body up into the next canter stride. The trailing forelimb quickly rebounds off the ground.Īs the front legs touch the ground, the thoracic sling along with all the muscles of the forelimbs contract to brace the leg and support the joints. Strain is put on the navicular bone via the deep digital flexor tendon as the horse lands on his heel with the toe turned upwards. The suspensory ligament and the deep digital flexor tendon are stretched to the extent that the fetlock often touches the ground. The trailing fore limb tends to be perpendicular to the ground (it lands first because the horse is cantering) and absorbs most of the impact (up to 2 ½ times the body weight of the horse). If the thoracic sling isn’t free, the front-end lands hard without the shock absorber action that is needed.Īs the horse is preparing to land after the jump, the horse must lift his head and neck up to shift the body weight back and slow down the rotation of the body axis, thus ensuring good balance on landing. The thoracic sling (especially the pectoral muscles) plays a crucial concussive role that protects the musculoskeletal system as well as the vital organs encased in the ribcage. ![]() The front limbs take the full weight of the horse as it lands. As the forelimbs extend for landing, the abdominal muscles contract to help lift the back while the gluteals and other muscles flex the hips, hocks and stifles to clear the jump. This signals for the hind limbs to flex in order to clear the jump and to extend the forelimbs in preparation for landing. Just after the bascule of the jump, the head and neck start to come up which shifts the center of gravity back. Tension on the nuchal and supraspinous ligaments (run from the poll to the sacrum along the topline of the neck and the back) also helps to raise the center of gravity further to increase height because the head and neck are extended forward and down. The folded forelegs bring the horse’s weight closer to his center of gravity, which increases speed. This helps lift the forelimbs to attain the necessary height to clear the jump. The trapezius, brachiocephalic and latissimus dorsi muscles contract to flex the shoulder and elbow joints and lift the scapulae. In the air, the horse’s body rotates around his center of gravity. The shape of the horse’s head, neck and back forms the bascule. To bascule (round the back) over the fence, the horse has to lower his head and raise his withers (thoracic sling). This month we’ll see the horse finish the jump as we look at the Suspension and Landing phases, and we’ll also address which Masterson Method Techniques work well for jumpers, and why. ![]() In Part 1 we looked at the Approach and Take-off phases. The jump was broken into the Approach, Take-off, Suspension and Landing phases. Last month we looked at the first part of an analysis of the biomechanics of jumping. ![]()
