Moderate to vigorous physical activity (MVPA) in relation to different minimal bout lengths.

<p>A) Proportion of participants (%) fulfilling ≥150 min of MVPA/week vs. minimal bout length. B) Median time in MVPA per week (min). Each bout length refers to the minimal number of consecutive min in MVPA required for inclusion in the calculation of accumulated time in MVPA, i.e. if bout length is 3 then bouts of length 1 and 2 are excluded.
