The Bosco Drop Jump is a test used to measure leg power. It involves jumping after a drop from various heights, ranging from 20 cm to 100 cm. This test is a part of the Bosco Ergo Jump System, which focuses on vertical jump techniques. In this article, we will explore the procedure, equipment required, scoring, and other relevant details of the Bosco Drop Jump.
Procedure
The Bosco Drop Jump is performed from five standardized drop heights: 20 cm, 40 cm, 60 cm, 80 cm, and 100 cm. The athlete stands on a box adjacent to a timing mat, with hands placed on the hips throughout the test. The athlete then drops down off the box, lands with bent knees, and immediately performs a maximal vertical jump. The technique used is similar to a Counter Movement Jump. The goal is to jump as high as possible and land with both feet on the mat simultaneously. Adequate rest should be allowed between trials.

The timing mat used in this test provides the time in the air, which can be used to calculate the vertical jump height. The jump height can be calculated using the formula: jump height = 4.9 x (0.5 x Time)2.
Advantages and Disadvantages
The Bosco Drop Jump is a valuable test for assessing leg power. However, it requires athletes with a good degree of leg strength, as the forces experienced are higher compared to a standard vertical jump test. One potential disadvantage is that standard-sized boxes used in the test may not be readily available and might need to be custom-made.
