Abstract

Power force velocity profiles of ballistic push offs are increasingly more used for the purpose of performance assessment. The main input parameter for such profiles is jump height. This study aims to propose and validate a simple low cost method for calculating jump heights based on 2D tracking of the trochanter. Furthermore a comparison with the existing low cost time in air method was carried out. Twelve athletes performed squat jumps on a force platform and were simultaneously filmed with a high speed camera. The error analysis depicted increased accuracy and precision as well as slightly stronger relation to the criterion for the 2D trochanter tracking compared to the time in air method. The result can be explained by the fact that the landing position of the athlete has no influence on the jump height calculation when using the trochanter tracking method.
