Values are means ± SD. Standard speed, walking speed at 1.5 m/s. T0, baseline; T1, follow-up 1 at 7.0 mo after baseline; T2, follow-up 2 at 12.8 mo after baseline; F, P, one-way ANOVA F and P values. F value has 2,18° of freedom. Italics denote P < 0.05.

^*P < 0.05, different relative to baseline.

^†P < 0.05, different relative to baseline and follow-up 1.
