NCT00899964

Brief Summary

Though possibly cost-saving, there is little scientific evidence for the effectiveness and reasonable modality of internet-delivered physical activity interventions in primary prevention. The aim of the study is to compare the influence of different personal and IT-based service levels on the activity outcome of obese, sedentary persons to evaluate the minimum level of service necessary for a maximum increase in activity and weight reduction.
