The high quality jump scale SPW has been specially developed for the measurement of pressures when jumping. The jump scale is often used by the professional associations, because it visualizes the forces that act on the joints at a jump even from a small height. So the scale jump illustrate, how loads act on the body when jumping (eg the jump from the cab of a truck / van or a stair step). So it is visualized that, at a small height three to four times of the body weight acts on the joints. When you jump from one meter height, the forces are about six times as high as in normal walking.
