*These analysis were based on a log transformation of the accelerometry measures with 0.5 being added to all scores to remove negative values.

^†The 1st quartile represents participants with the best function whereas those in the 4th quartile had the poorest function. The time (gait speed) for each quartile for the 400-m walk was as follows: quartile 1 = ≤428s (≥0.934 m/s; quartile 2 = >428 s to ≤484 s (<0.934 m/s to ≥0.826 m/s); quartile 3 = >484 s to ≤568 s (<0.826 m/s to ≥0.704 m/s); quartile 4 = >568 s (<0.704 m/s).
