Six-minute walking versus shuttle walking: responsiveness to bronchodilation in chronic obstructive pulmonary disease.

ABSTRACT:

Background

The responsiveness of the endurance shuttle walk to functional changes following bronchodilation has recently been reported. The current literature suggests that the 6 min walking test (6MWT) is less responsive to bronchodilation than the endurance shuttle walk.

Aim

To compare bronchodilator-induced changes in exercise performance with the 6MWT and the endurance shuttle walk.

Methods

In a randomised, double-blind, placebo-controlled, crossover trial, 14 patients with chronic obstructive pulmonary disease (forced expiratory volume in 1 s (FEV(1)) 50 (8)% predicted) completed two 6MWTs and two endurance shuttle walks, each preceded by nebulised placebo or 500 microg ipratropium bromide. Cardiorespiratory parameters were monitored during each walking test with
