| - An alternative outcome for physical activity that is often used is ‘MET-minutes’. However, if updated MET values derived from the 2011 version of the Ainsworth’s compendium are used, MET values for cycling conducted as a commuting or leisure-time activity should be set at 5.0 to avoid overestimating vigorous PA. Moreover, it is best to use ‘MET-minutes in MVPA’, thus MET-minutes for the moderate to vigorous levels (selecting MET ≥ 4) because of the high risk of obtaining imprecise estimates for light PA minutes. | - An alternative outcome for physical activity that is often used is ‘MET-minutes’.

| - Compared with occupational PA, leisure time and commuting PA demonstrate a much clearer association with health outcomes. Therefore, we recommend to make a substantiated decision to include or exclude occupational PA in the PA measure you want to use, since PA in the various domains seem to represent different kinds of activity with differential health effects.\\ | - Compared with occupational PA, leisure time and commuting PA demonstrate a much clearer association with health outcomes.
