| Slow walking | 3.6±0.5 (2.9–5.2) | 3.3±0.5 (2.4–5.2) |
| Fast walking | 5.1±0.8 (3.3–6.9) | 5.1±0.8 (3.7–6.9) |
Mean±SD (minimum–maximum). *p<0.05, **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).
DB_METs, metabolic equivalents (METs) measured using the Douglas bag method.
