Abstract: A method for measuring the force generated by at least one athlete jumping on a measuring platform includes generating exercise data for jumping exercises. The exercise data is presented to the athlete. As the athlete performs jumping exercises on the measuring platform, a jumping force of the jumping exercises is measured and recorded as measurement data for the measured jumping force. The measurement data is sent to a data processing system that evaluates the measurement data and generates performance data from the measurement data. Expert data is determined from the performance data, and either the performance data or the expert data or both, are outputted to the athlete or to someone monitoring the performance of the athlete.
