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 .
The Incremental Shuttle Walk Test in Older Brazilian Adults
Background : Despite widespread use of the incremental shuttle walk distance ( ISWD ) , there are no reference equations for predicting it . Objectives : We aim ed to evaluate ISWD in healthy subjects and to establish a reference equation for its prediction . Methods : 131 Brazilian individuals ( 61 males ; 59 ± 10 years ) performed 2 walk tests in a 10-m long corridor . We assessed height , weight , body mass index , forced expiratory volume in 1 s , forced vital capacity and self-reported physical activity  . Results : Mean ISWD was greater in males than in females ( 606 ± 167 vs. 443 ± 117 m ; p < 0.001 ) . ISWD correlated significantly ( p < 0.05 ) with age ( r = –0.51 ) , height ( r = 0.54 ) and weight ( r = 0.20 ) . A predictive model including age , height , weight and gender explained 50.3 % of the ISWD variance . In an additional group of 20 subjects prospect ively studied , the difference between measured and predicted ISWD was not statistically significant ( 534 ± 84 vs. 552 ± 87 m , respectively ) , representing 97 ± 12 % of the predicted value calculated with our reference equation for ISWD . Conclusions : This reference equation including demographic and anthropomorphic attributes could be useful for interpreting the walking performance of patients with chronic diseases that affect exercise capacity
