Vertical jump testing has become a staple of assess athletes. Decades ago the standard coach had to rely on the jump and reach test in order to testing jumping ability. Thanks to new technology and research, today coaches can now better analyze sport-specific jumping performance and more easily measure variables other than simple jump height. Jump height remains the most popular measure, but that is slowly changing as more technology enters the weight room. The advantages and disadvantages of different methods of vertical jump testing will be discussed below, with particular reference to the procedures required to obtain valid results. This is important because if the method you use is not valid or measuring accurately what it is intended to, your assessment will be of little value.
