Introduction: We report on experiences in implementing a system to support the individual guidance of training in health promotion programs aiming to increase participants' regular level of physical activity.
Methods: We used an iterative development approach considering data privacy and security aspects, followed by a phase of field testing and continuous further development.
Results: Our preliminary results comprise identified clinically relevant parameters, suitable data collection methods, experienced privacy and security challenges and a glance on our developed prototype system.
Discussion: We consider our results to be of interest for others doing related research. The most important requirements for a simple supporting system can be fulfilled with established solutions in the short run. A more adaptable and flexible system with an increased level of support in analysing the data, which we aim to achieve, leads to currently open research challenges.
