Abstract

The invention relates to the field of mobile training data acquisition in sport, particularly in strength training, body building, fitness sports and rehabilitation, as well as the analysis of said training data. The invention involves a method and a mobile device (1) for precise acquisition of multiple training data. The multiple training data includes, for example, the time-path curve of the force application point of the training load, the mechanical work and the tension duration of eccentric and concentric muscle length changes and isometric muscle contractions. An analysis of the training data is based on a training model (25).
