Before conducting the test, it is essential to explain the procedures to the participant and conduct a screening for any potential health risks. Informed consent should be obtained, and basic information like age, height, body weight, gender, and test conditions should be recorded. Additionally, the timing mat measurement must be checked and calibrated, and the participant should perform a suitable warm-up.
Procedure:
The height of the jump is determined by using a timing mat that measures the duration the feet are off the mat. The subject stands barefoot or in socks on the mat with the weight evenly distributed over both feet. With the knees bent to 90 degrees, the participant squats down and, when ready, jumps vertically as high as possible, landing back on the mat with both feet simultaneously. A sufficient rest period should be allowed between trials. The take-off must be from both feet, without any initial steps or shuffling. The best of at least three attempts is recorded, and participants can continue jumping as long as improvements are being made.
Scoring:
The timing mat provides the duration in the air, which can be used to calculate the vertical jump height using the formula: jump height = 4.9 x (0.5 x Time)^2).

Disadvantages:
It’s important to note that the accuracy of the test can be compromised if the subject does not bend their knees to the required 90 degrees during each jump, as this affects the calculated jump height.
Comments:
Participants may benefit from practice and should be encouraged to give their maximal effort for each attempt.
