Mean±SD, **p<0.01, ***p<0.001.

Slow walking and fast walking were excluded from statistical analyses because the walking speed differed between the groups.

Slow walking (Younger: 55 m/min, Elderly: 50 m/min), normal walking (both groups: 70 m/min) and fast walking (Younger: 100 m/min, Elderly: 90 m/min).
