Having a standing center of gravity that is higher is a distinct advantage to an athlete participating in the high jump. This is why coaches would want to recruit tall athletes to participate in this particular event. The higher the standing center of gravity, the less the athletes have to work to get their body into the air and ultimately over a specific bar height. Shorter athletes must be very gifted in terms of muscle development and fiber types in order to have the explosive capability to reach elite-level heights in the high jump.

The amortization phase is crucial to distinguishing the average athlete from the elite athlete. Successful execution of this timing phase is the result of training and motor learning from plyometric drills. All individuals have a genetic limitation in speed and power; however, they all have a window of opportunity to maximize their abilities if taught and trained properly. Even small differences can lead to magnificent outcomes if they are executed at the proper time. Studies examining great jumpers, sprinters, or other athletes who rely on the speed and strength of their muscles show that these elite athletes do not spend much time on the ground during sport maneuvers.

The concept of the inverted funnel (first described by John Frappier) is based on the fact that athletic movements often require the individual to move the feet out from under the body’s center of gravity and then recover the position quickly in order to regain balance and stability. The Frappier footwork drills (see chapter 9) were designed to teach the athlete to maintain the center of gravity in a relatively constant position while the feet rapidly work out from under it in all directions. The result is improved kinesthetic awareness, or that sense of where the body is in relation to the environment.
