Dr. Lindsay St. George, Dr. Ma biomechanics. The horse approached the fence and he shortened the pace, lowered the speed, tried to collect energy and became a bit like a spiral spring.
The reduction in speed is usually produced by the forelimb, which strikes the ground at a more acute angle, reduces forward speed and begins vertical development (upward)velocity.
The head and neck stretch forward to reduce the center of mass, while the scraps stretch forward to stretch the elastic structure (i. e.
Tendon and ligament)of the limb.
These are energy.
The storage device stores the elastic strain energy, just like stretching the rubber band and then releasing the rubber band.
