High Jump Mechanics
The approach phase is the running at the start to build speed and momentum , needed for the takeoff and to clear the bar. A modified "J" approach is the common lingo. Athlete runs a "J" or a "hook."
Run forward and close to the bar, transition into a curve of the running approach.
The explosive takeoff takes the energy from the approach. Before leaving the ground, the body leans backward and inward and the arms swing behind. Just before the jump, the arms move forward and up, giving extra downward pressure to the legs and feet for higher flight. Both a single arm or double arm swim method is in use.
The non-takeoff leg, also called the free leg drives up as high as possible.
Least important to the approach and takeoff, yet clearly more visual. Once the athlete leaves the ground, the path of the flight for the body cannot be changed. An effective flight check body position of head, shoulders, hips, legs and feet.
The head and shoulders clear the bar, then the head tips backward. As the head leans back, the hips come up. An arch of the body in the air aid so that the legs and feet can clear the bar. As the feet near the bar, a forward move of the head gives the feet height.
Land on the upper part of the back.
