The one-leg vertical jump test is a variation of the standing vertical jump that measures the ability to jump off one leg from a standing position. This test is best conducted using the Vertec® equipment.
Equipment and Pre-Test Procedures
Before conducting the test, it is important to have the necessary equipment, such as the Vertec® or a similar apparatus. Additionally, you should explain the test procedures to the subject, perform a screening of health risks, and obtain informed consent. Record basic information such as age, height, body weight, gender, and test conditions. Lastly, ensure that the subject performs a proper warm-up.

To start the test, record the initial standing height by having the subject stand below the apparatus with both feet flat on the ground and stretching up one arm as high as possible. The subject should then stand sideways to the wall or measurement apparatus, with the leg to be jumped off closest. They can swing their arms and free leg as much as they want before leaping vertically as high as possible. The arms can be used to assist in projecting the body upwards. The subject should reach up with one arm as high as possible, and the swing of the arm should be timed to mark the highest point of the jump. Record the best of three attempts and measure for each leg.
Scoring and Disadvantages
The score for the one-leg vertical jump test is the difference in distance between the standing reach height and the jump height reached. The jump height is recorded as a distance score, representing the height reached above the standing height. This test allows for a comparison between the legs to identify any discrepancies, as well as a comparison to the results using both legs.

It should be noted that technique plays a significant role in maximizing the score, as the subject must time the jump correctly to reach the marker at the peak of the jump. Additionally, the effective use of the arms can impact the jump height. Another disadvantage of this test is that the Vertec® equipment can be expensive compared to the chalk and wall vertical jump method. Finally, athletes may attempt to inflate their jump score by not reaching up fully when measuring the standing height.
FAQs
