  1. P-values result from Kruskal-Wallis test; PA = physical activity; MVPA = moderate to vigorous PA; BL = bout length; % time > median BL = percentage contribution to the total time in bouts greater than the median bout length; *n = 156 (33/82/41 for rare/average/frequent).**significant p values due to different variances.
  2. Median (5%, 95%).
