Abstract

Purpose: This cross-sectional study compared the physiological responses and dynamic hyperinflation (DH) of the Glittre-ADL test (TGlittre) and its specific tasks in patients with chronic obstructive pulmonary disease (COPD).

Methods: Thirty patients with COPD performed the TGlittre. The individual tasks included stand up and sit down (T_SS); climb up and down stairs (T_STAIRS); walk on a flat surface (T_WALK); and move objects onto and off a shelf (T_SHELF). While performing these tasks, the physiological responses were evaluated and inspiratory capacity measured before and immediately after the tests.

Results: All physiological variables and inspiratory capacity were different at the end of the TGlittre and its tasks compared with baseline (P < .05). For most of the physiological variables, there were no significant differences between T_SHELF and T_WALK (P > .05), which were the tasks with the greatest physiological requirement, whereas the T_SS represented the lowest metabolic, cardiovascular, and ventilatory demands among TGlittre's tasks. DH did not differ significantly among TGlittre's tasks.

Conclusions: T_WALK and T_SHELF were the tasks that resulted in greater physiological overload, whereas T_SS induced the lowest metabolic and ventilatory demands. Despite this, DH did not differ among the TGlittre's tasks in patients with COPD.
