Abstract [en]

While the mechanisms underlying exercise limitations and increased symptoms during leg activities in individuals with COPD have been investigated in detail, knowledge of potential differences between leg and arm activities is not well understood and results from individual studies are contradictory.The aim of the present study was to synthesize responses during arm activities relative to leg activities in people with COPD. Any study with a cross-sectional comparison of acute physiological (e.g., cardiorespiratory, metabolic) and symptomatic responses to arm versus the leg activities were included. Studies were sub-grouped based on the type of activity performed (ergometer cycling, resistance exercises, or functional activities).18 studies with 423 individuals with COPD were included. Leg cycling was performed at a greater load (20 W) and resulted in greater tidal volume (137 mL), minute ventilation (4.8 L/min), and oxygen consumption (164 mL/min) than arm cycling, while symptomatic responses were similar. Resistance exercises resulted in similar physiological and symptomatic responses between arm and leg activities. Results of studies on functional activities varied considerably and were dependent on the type and intensity of the activity performed.Physiological responses were in general greater during leg- compared to arm activities except during resistance training exercises. The perception of exertional symptoms seems to be intensity dependent and not activity dependent. Strategies used to increase exercise tolerance should not be based on whether the arms or the legs are used, but rather on the specific activity performed.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA1190.This is an ERS International Congress abstract.
