Jump and Reach (J&R)
Back to overview
1. Test objective
Determination of the explosive strength of the lower extremities.
2. Description of the task
In the Jump & Reach Test, the test person stands in the starting position to the side of the wall and directly next to the jump mark. Before jumping, the test person's reach height is determined by marking the maximum extension height of the fingertips on the wall with chalk. The test person faces the wall, the tips of the feet touch the wall and the test leader fixes the shoulder blades. Is it okay to stand on tiptoe?
The test person now jumps upwards from the parallel stance with both legs without an upward step and taps the wall with the fingers at the highest point. Momentum is allowed and is done by bending the knee and upper body and extending the arms. The test leader reads the jump height using the L-rail.
3. Test materials
|3.1||Space requirement: approx. 3 m2 on one wall|
Time and person requirements: 2 test leaders can test 20 subjects within 30 minutes
|3.3||Equipment and material: chalk, magnesia, 4-m measuring tape, small boxes, L-rail|
4. Test setup
A meter tape measure is attached to a free wall. A box is placed near the tape measure for a test leader to facilitate reading off the jump height achieved. A container of magnesia is provided at the test station for test participants to apply to their fingers to later leave a mark on the wall. The jump height can be read off the measuring tape with the aid of an L-bar applied to the mark left behind.
5. Measurement recording
The measured value is recorded metrically (step height). It is recorded with an accuracy of 0.1 cm. Standard tables are available for processing the measured values.
Numerous studies are available with information on mean values and standard deviation (see Beck & Bös, 1995, p. 106ff).
6. Test instruction
This test is about jumping as high as you can. Before the jump, we measure how tall you are when you stretch both arms all the way up. Then you stand parallel to the wall at the marker and jump as high as you can. During the jump you take your arms up with you. At the highest point of your jump you should touch the wall with the fingers of the arm stretched upwards.
7. Special notes
The test station is performed with sports shoes.
The test person should apply sufficient magnesia to the fingers.
Sources of error
The test person jumps off with one leg.
