The vertical jump test is a popular method for measuring an individual’s vertical jump height. In this article, we will explore a variation of the test that involves no arm movement. By eliminating the swinging of the arms, this protocol isolates the leg muscles and reduces the impact of arm coordination on the jump height measurement. This specific method is utilized in the eTID program, which focuses on developing athletic performance.
Equipment and Pre-Test Procedures
Before conducting the test, you will need the following equipment: a measuring tape or marked wall, chalk or other marking material, and a room with a ceiling height of at least 4 meters or an outside wall of similar height. Additionally, it is crucial to perform a pre-test routine. This includes explaining the test procedures to the participant, screening for any health risks, obtaining informed consent, and recording basic information such as age, height, body weight, and gender. It is also recommended to warm up adequately before the test.

The test begins by determining the reach height of the participant. Standing side-on to the wall, with both feet flat on the ground, the participant reaches up as high as possible above their head, leaving a mark on the board or wall. The reach height is recorded to the nearest centimeter.
Next, the participant stands slightly away from the wall, with one hand on the hip and the other stretched upwards, without swinging the arms. The subject crouches down and then leaps vertically as high as possible, aiming to touch and mark the wall at the highest point of the jump. The crouch depth and any bouncing (with feet remaining on the ground) are at the participant’s discretion. The take-off must be from both feet, with no initial steps or shuffling. The best of at least three attempts is recorded, and participants may continue jumping as long as they are improving their performance.
Scoring and Considerations
The jump height is calculated as the difference between the maximum jump height and the reach height, recorded to the nearest centimeter. It is important to record all three values to ensure accuracy.

While this test is relatively simple and quick to perform, the technique plays a significant role in maximizing jump height. Timing the jump to mark the wall at the peak of the jump is crucial. Additionally, the amount of knee bending before the jump can also affect the results. Encouraging participants to practice and find the best technique for their abilities is recommended.
Advantages and Disadvantages
The no arm vertical jump test offers several advantages. It is straightforward and efficient, making it possible for individuals to self-administer the test. However, technique and practice are essential factors that can influence jump height, as participants need to coordinate their movements effectively.
FAQs
Q: Can I perform the no arm vertical jump test on my own?
A: Yes, this test can be self-administered, making it convenient for individuals who want to assess their vertical jump height.
Q: How many attempts should I make during the test?
A: It is recommended to perform at least three attempts and record the highest jump height achieved. Continued attempts can be made as long as there is improvement in performance.
Q: How does knee bending before the jump affect the results?
A: The amount of knee bending before the jump can influence the jump height. Participants should try different techniques and practice to find the most effective approach for their abilities.
Summary
The no arm vertical jump test is a method used to measure an individual’s vertical jump height without allowing arm movement. By isolating the leg muscles and reducing variation in arm coordination, this test provides a more accurate assessment of leg power. It is a simple and quick test that can be self-administered, making it convenient for athletes and fitness enthusiasts alike. By following the proper test procedures and focusing on technique, participants can achieve optimal results and monitor their progress over time. Improve your vertical jump and track your development with the no arm vertical jump test.
