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 .
Endurance shuttle walking test: responsiveness to salmeterol in COPD
Few studies have shown that the endurance shuttle walking test ( ESWT ) is responsive to treatment in patients with chronic obstructive pulmonary disease ( COPD ) . This exercise test needs to be further investigated because of its relevance for activity of daily living . The aim of the present study was to evaluate , in patients with COPD , the responsiveness of the ESWT in detecting improvement in walking performance after a single dose of salmeterol . In a r and omised , double-blind , placebo-controlled crossover trial , 20 patients with COPD performed two ESWT at 80 % of peak capacity 2.5 h after inhaling either a placebo or 50 µg of salmeterol  . Cardiorespiratory parameters were monitored during each walking test . Inspiratory capacities and Borg ratings for dyspnoea were obtained every other minute throughout the tests . Compared with placebo , salmeterol produced a significant change in lung function and a significant improvement in walking performance ( mean±sd difference in time : 117±20 s ; difference in distance : 160±277 m ) . At isotime ( the latest exercise time that was reached on both ESWT ) , a significant reduction in dyspnoea was observed after bronchodilation . Bronchodilation with salmeterol reduced dyspnoea during walking and improved walking capacity in patients with chronic obstructive pulmonary disease . These findings provide further support for the use of the endurance shuttle walking test as an evaluative tool in chronic obstructive pulmonary disease
