Introduction: The intention of mobile motion assistance is to support athletes (leisure time and elite sport) in their training. A mobile device gathers performance parameter values on the spot and sends them to a server component for further analyses. The classification of the data and generation of (immediate) feedback is based on expert knowledge. Methods: A prototype system for monitoring, transmitting and processing sports performance data for the purpose of providing feedback has been developed (cf. Baca et al., 2010). During training, athletes are equipped with a mobile device and wireless sensors communicating via the ANT protocol in order to acquire biomechanical, physiological and other sports specific performance parameters. The measured data is buffered locally and forwarded via Internet to a server. The server provides experts with remote data access, analysis and (partly automated) feedback routines. In this way, experts are able to analyse the athlete's performance and return individual feedback messages from remote locations. Results and Discussion: Three use cases comprising application fields of the MMA have already been realised (Preuschl et al., 2010). Our first implementations concern running and mountain biking, two endurance sports. Furthermore, selected weight training machines have been equipped with sensor and communication technology for giving feedback during resistance exercises. The prototype installations of the MMA have been set up for use during physical education activities. Interactive communication technology is thus provided to teachers and students. Characteristic parameters of the performances of a whole class can be supervised continuously. In this way the teachers are able to monitor performance and activity data of a large number of students and may give the students individual feedback.
