  1. Xini: Initial horizontal position of the body's center of mass. Yini: Initial vertical position of the body's center of mass measured from the floor. Xt.o.: Horizontal position of the body's center of mass at the instant of take-off. Yt.o.: Vertical position of the body's center of mass at the instant of take-off measured from the floor. VXt.o.: Horizontal velocity of the body's center of mass at the instant of take-off. VYt.o.: Vertical velocity of the body's center of mass at the instant of take-off. VXYt.o.: Resultant velocity of the body's center of mass at the instant of take-off. Xmax: Maximal distance traveled by the body's center of mass. (Note: this value was negative in the vertical jumping, as the model jumped up slightly backwards.) Ymax: Maximal height reached by the body's center of mass measured from the floor. Egain: Energy gain of the body's center of mass throughout the jumping motion.
