Presentation transcript:

a) Inspiratory capacity (IC) in asthmatics with (n=13) and without (n=7) expiratory flow limitation (EFL) at various levels of exercise, expressed as a percentage of maximal work rate (WRmax). a) Inspiratory capacity (IC) in asthmatics with (n=13) and without (n=7) expiratory flow limitation (EFL) at various levels of exercise, expressed as a percentage of maximal work rate (WRmax). Patients with EFL developed a progressive decline in IC with increasing work rate. Data are presented as mean±sd. *: p=0.05; #: p=0.03. b) Relationship between maximal oxygen uptake (V′O2max) and change in IC (ΔIC) from rest to 90% of WRmax. Each data-point represents a single patient. The regression equation is y=84+0.3x±11 (se), r=0.48, p=0.03. c) Asthmatic patients with EFL during exercise tended to have a higher Borg dyspnoea score throughout exercise compared to non-EFL asthmatics. EFL patients started to experience higher dyspnoea at 66% WRmax, while those without EFL experienced higher dyspnoea scores at 90% WRmax. Data are presented as mean±sd.
