^aDutch physical activity norms:
- DNHPA Dutch Norm for Health-enhancing Physical Activity: Thirty minutes or more of at least moderate-intensity aerobic (endurance) physical activity on at least five days each week
- Fit-norm: Twenty minutes or more of vigorous-intensity physical activity on at least three days each week
- Combi-norm: Meeting the DNHPA and/or Fit-norm
