  1. Significance demarcation based on pairwise comparisons of the three levels of task
  2. NWS self-selected walking speed, FWS self-selected fast walking speed
  3. aDenotes ‘walking + texting’ condition differs significantly from the walking only condition (P < 0.05)
  4. bDenotes ‘walking + talking on a phone’ condition differs significantly from the walking only condition (P < 0.05)
