Six minute walk distance

Six minute walk test

Walk tests

Background: The six minute walk test (6MWT) is the most commonly used exercise test in pulmonary rehabilitation; however, the paucity of six minute walk distance (6MWD) reference values from population-based samples limits data interpretation in patients. This study was undertaken to determine 6MWD in a population-based sample of healthy subjects and to identify predictors of 6MWD in this group. Methods: Seventy Caucasian subjects (33 males) aged 55-75 years performed three tests using a standardised protocol. 6MWD was defined as the greatest distance achieved from the three tests. Other measurements included height, leg length, weight, forced expiratory volume in 1 s (FEV1), exhaled carbon monoxide and self-reported physical activity including habitual walking. Results: The average 6MWD was 659±62 m (range 484-820 m). Males walked 59±13 m further than females (P < 0.001). Height (r = 0.54, P < 0.01), weight (r = 0.25, P < 0.05) and FEV1 (r = 0.48, P < 0.001) were significantly correlated with 6MWD. Forwards stepwise multiple regression showed height (R2 change = 0.294) and FEV1 (R2 change=0.045) to be independent predictors of 6MWD (P < 0.05), explaining 33.9% of the variance. Conclusions: 6MWD in this healthy population-based sample of males and females exceeds values previously reported. Height and FEV1 were identified as significant independent predictors of 6MWD in this group.
