Method ological factors affecting 6MWD include track length , encouragement , supplemental oxygen and walking aids .
Supplemental oxygen also affects ISWT and ESWT performance .
Responsiveness was moderate to high for all tests , with greater responsiveness to interventions that included exercise training .
The findings of this review demonstrate that the 6MWT , ISWT and ESWT are robust tests of functional exercise capacity in adults with chronic respiratory disease
This systematic review examined the measurement properties of the 6-min walk test ( 6MWT ) , incremental shuttle walk test ( ISWT ) and endurance shuttle walk test ( ESWT ) in adults with chronic respiratory disease .
Relationship between daily physical activity and exercise capacity in patients with COPD.
BACKGROUND Exercise training programmes for patients with COPD are effective in improving exercise capacity . The few trials that have investigated the effects of exercise programmes on daily physical activity show contradictory results . AIM To investigate the relation between daily physical activity level and exercise capacity in patients with COPD using data of a r and omised controlled trial in which the exercise intervention was aim ed at improvement of both physical activity and exercise capacity ( the COPE-II study ) . METHODS These are secondary analyses of the COPE-II study , a r and omised controlled trial in which a community-based physiotherapeutic exercise programme was evaluated .  Daily physical activity  was measured with a pedometer ( steps/day ) . Exercise capacity  was measured with an incremental maximal cycle ergometer test , the incremental ( ISWT ) and endurance shuttle walk test ( ESWT ) . Pearson correlation coefficients were calculated . RESULTS At baseline , correlations between steps/day and VO(2peak ) , ISWT ( m ) , ESWT ( m ) and ESWT ( s ) were 0.54 , 0.59 , 0.44 , and 0.34 , respectively ( all p < 0.01 ) . In the  intervention group , correlations between change in steps/day over 7 months and change in ISWT ( m ) , ESWT ( m ) and ESWT ( s ) were 0.47 , 0.41 , and 0.38 , respectively ( all p < 0.01 ) . In the  control group , these same correlations were weak to non-existent . CONCLUSIONS A moderate to weak relationship was found between daily physical activity and exercise capacity . These results strengthen our beliefs that exercise interventions need to target not only exercise capacity but also behaviour change with regard to daily physical activity to achieve improvements in both parameters
