Equipment: Vertec machine, backboard, or wall
1. Measure standing reach, in shoes, on the Vertec or wall. Stand with both feet flat on the ground, legs and torso straight. Reach up with a straight arm, wrist, and hand. With your fingers, touch at the highest point.
2. Jump straight up as high as possible and, with a straight arm, tap the Vertec device or mark the wall at the highest point (figure 1.1). No shuffle steps, side steps, drop steps, or gather steps are allowed.
3. Make two attempts. If, on the second attempt, you reach a higher height, a third attempt is awarded.
4. The vertical jump is the difference, in inches, between the standing reach and the jump reach.
Equipment: Vertec machine, backboard, or wall
1. Measure standing reach, in shoes, on the Vertec or wall. Stand with both feet flat on the ground. Torso and legs are straight. Reach up with a straight arm, wrist, hand, fingers touching at the highest point.
2. Maximum approach distance is measured from the free-throw line extended in a 15-foot (4.6 m) arc to the baseline.
3. Take as many steps toward the Vertec, backboard, or wall as necessary to acquire a maximum vertical jump. Everyone is required to start within the 15-foot arc, and each athlete has the choice of a one- or two-foot takeoff.
4. Make two attempts. If on the second attempt you reach a higher height, a third attempt is rewarded.
