Introduction
Asthma is one of the most common chronic condi-
tions worldwide [1]. In adults, consequences of asthma
include dyspnoea, wheezing and chest tightness on exer-
tion and in response to other triggers, reduced exercise
capacity and co-morbid conditions such as depression,
anxiety and impaired quality of life (QOL) [2–4]. The dis-
ability associated with asthma has been reported to be
greater in individuals with more severe disease, in those
who are older and in those who have poorer control of
their asthma [5]. A negative attitude to exercise is com-
mon due to a fear of symptoms occurring during or after
exercise and to a lack of specific advice about exercise
from health professionals. Such attitudes often lead to a

Abstract
Background: Some individuals with moderate/severe per-
sistent asthma develop irreversible airway obstruction.
These individuals present with dyspnoea, exercise intoler-
ance and impaired quality of life (QOL), all of which could
potentially be alleviated with exercise training. Objective: To
investigate whether exercise training improves functional
exercise capacity and QOL in middle-aged and older adults
with fixed airway obstruction asthma (FAOA). Methods: 35
subjects aged 67.8 8 10.6 years, with FEV
1
59 8 16% of pre-
dicted, were randomised to a 6-week ‘intervention’ period of
supervised exercise training (n = 20) or usual care (n = 15).
This period was preceded by a 3-week run-in period during
which asthma control was assessed weekly. Functional exer-
cise capacity (6-min walk distance, 6MWD) and QOL (Asthma
QOL Questionnaire, AQLQ) were measured before, immedi-
ately following and 3 months after the intervention period.
Results: 34 subjects (exercise group, n = 19, and control
group, n = 15) completed the intervention period. Relative to
the control group, the exercise group had greater improve-
ments immediately following and 3 months after the inter-
vention in the AQLQ symptom domain (0.61, p = 0.001, and
