Demographics and walking ability in the three age groups.

Young (20–39)	41	29.1 ± 5.0	51.2	70.1 ± 14.5	172 ± 8	1.15 ± 0.17	3.37 ± 0.45	4.41 ± 0.63	724 ± 74

Group comparisons were made using one-way ANOVA with post-hoc t-tests corrected for multiple comparisons (Bonferroni). Values given are means ± standard deviation. Bold type indicates significant difference compared to both other age groups at the p ≤ 0.05 level. T25FW; timed 25-foot walk, 10MWT; 10-metre walk test, 6MWT; 6-minute walk test.
