It is difficult to compare our study findings with those
of other studies of exercise training in adults with asthma
as our subjects were significantly older [31–33] and had
more severe airflow limitation [31, 32] . In addition, the
two studies that have reported improvements in HRQOL
did not use a questionnaire specifically developed for individuals
with asthma and included interventions other
than exercise training, such as patient education, breathing
retraining, relaxation and recreational techniques, or
nutritional advice and psychological counselling [25, 31] .
Of note was that one of these studies did not include a
control group [25] , and both studies included asthma and
COPD subject cohorts [25, 31] . Our findings are, however,
generally consistent with those of other studies that have
found no effect of exercise training on lung function or
asthma control [6] .
