Burke & Morrow - Two of the Nations Foremost Lady High Jumpers - Part One: Taylor Burke

The high jump can be broken down into three phases:  the run-up, takeoff and bar clearance. After the  takeoff, the center of gravity of an athlete follows a fixed path called a parabola. The athlete’s  parabolic path should reach the maximum possible peak height as the athlete goes over the bar.  As the center of gravity travels along the parabola, the body should rotate around the center of gravity in a way that will allow the successful clearance of a bar set as high as possible.    In today’s most popular jumping  technique, the Fosbury-fIop, the rotation consists of a "twist" (a rotation around the longitudinal axis of the body) which turns the back of the athlete toward the bar, and what some refer to as a "somersault" (a rotation around a transverse axis) which makes the shoulders go down and the knees go up.
