The Drop Jump Test is a plyometric exercise used to measure an athlete's lower body power and reactive strength. It involves dropping from a height and immediately jumping upward as high as possible upon landing. The Key Differences. So, when deciding which type of jump is best for you or your athletes, keep the outcome goal in mind. Depth jumps are used for maximal power output and achieving maximal height.The origins of the first of these 2 derivatives can be traced back to the work of Verkhoshansky , who describes a “depth jump” exercise where the athlete steps off a box and then performs a vertical jump for maximal height on landing.

Though the terms ‘drop-jump’ (2, 3) and ‘depth-jump’ (4, 5) are often used interchangeably in both practical and research environments, the term ‘drop-jump’ is preferred as it implies the athlete simply drops from the box.s study was to examine the relationship between lower-body muscle structure and vertical jump performance. Twenty-five resistance-trained men (age, 23.3 ± 3.2 years; height, 176.1 ± 7.4 cm; and weight, 86.2 ± 11.6 kg) took part in both anatomical and jump performance testing. Muscle fascicle thickness, fascicle length, and pennation angle were analyzed for the vastus .
