Feedback from physical activity monitors is not compatible with current recommendations: A recalibration study

This study demonstrates that feedback from sophisticated wearable devices is incompatible with current physical activity recommendations. Without adjustment, people will erroneously form the view that they are exceeding recommendations by several fold. A more appropriate target from self-monitoring that accounts for normal moderate-to-vigorous lifestyle activities is ~ 1000 minutes per week, which represents ~ 15% of waking time.
