Jumpers Flashcards
Describe the movement of the neck and the center of gravity during the stride before the fence
Stretches downward and forward
Know when the flight of the jump (trajectory) is determined
At takeoff
Describe the flexion/extension of the hindlimbs during their last ground contact before the jump and the effect on energy
As hindfeet impact the gournd the legs are extended and then the hocks, stifles, and hips flex storing energy
Know the effect of poor jumping technique on the effort needed to clear a jump
Poor jumping technique leads to higher forces at take off and landing.
0.80 m with poor form is equivalent to 1.3 m with good form
Know the significance of consistently jumping to one side, say to the left. It may indicate problems in which areas
Thoracolumbar, SI or upper hindlimb
Know which muscles prevent the horse’s trunk from crashing to the ground at landing
Serratus ventralis and pectorals
Know which front limb (leading limb or trailing limb) may have a problem when the horse consistently lands with the same front limb leading and why
Leading limb, trailing limb takes on more concussion on landing
Know where the center of gravity is at landing
Shifted very far forward in front of the front feet and in front of the base of support
Know why the hindlimbs flex immediately on landing (2 reasons)
To absorb impact and store energy for the next stride
Know what it may indicate when a horse consistently jumps from one lead
Always jumps from the left lead may have problem with the left front or left hind
When does a horse get its jumping style
At a young age – 4 months
