Schematic diagram of the potential psychophysiological mechanism of perception of breathlessness in obese adults with dyspnoea on exertion. 1: increased afferent feedback; 2: increased corollary discharge from the respiratory control centre; 3: decreased gating threshold for sensory transmission; 4: decreased or increased input from gating modifiers. V′O2: oxygen uptake; PaCO2: arterial carbon dioxide tension. Reproduced from [24] with permission from the publisher.
