EN Vertical countermovement jump is a very simple and common method for assessing the jumping ability of athletes. There are different techniques for measurements of the flight height, e.g. using motion capture systems or accelerometers. In this paper for estimating the flight height the measurements coming from the force plates are used. Furthermore different methods can be applied for calculating the flight height based on these measurements. In these paper four methods of calculating the flight height during the vertical countermovement jump based on the measurements from the force plates are compared (the flight time method, the take-off velocity method, the work-energy method and the center of jumper’s body vertical position method). In addition for two of these methods (the take-off velocity method and the center of jumper’s body vertical position method) the authors applied two different methods of numerical integration (the trapezoidal rule and based on the cubic spline interpolation).
