N2 - Respiratory muscle weakness is a common feature of a multitude of cardiopulmonary diseases
and has led to an increasing awareness that respiratory muscle weakness can be a compounding
factor in many diseases associated with higher morbidity and mortality. The aim of the study was
to ascertain the effect of breathing and aerobic training on manual volitional respiratory muscle
strength and function in moderate, persistent asthmatics. Eighty-eight previously sedentary,
moderate, persistent asthmatics were divided into either a non-exercising control (NON),
endurance trained (ET), inspiratory and expiratory trained (IEB) or endurance trained combined
with inspiratory and expiratory trained (COM) group. The exercise groups trained three times
weekly over an eight-week period. The ET programme (n = 22) consisted of walking/jogging at
60 of individual age-predicted maximum heart rate, the IEB programme (n = 22) of inspiratory
and expiratory training in a semi-recumbent position at varying inspiration, expiration ratios
while the COM programme (n = 22) employed a combination of the ET and IEB programmes.
The NON (n = 22) received no prescribed exercise and were instructed to continue their usual
activities. ET, IEB and COM resulted in significant (p = 0.05) strength improvements in eleven
of the thirteen measured inspiratory muscles. ET and COM resulted in significant strength
improvements in all seven of the measured expiratory muscles, while IEB improved the strength
of five of the seven measured expiratory muscles, excluding left lattisimus dorsi and left
quadratus lumborum. There were no significant changes in any of the measured variables in the
NON group. Increases in respiratory muscle strength as a result of exercise training are essential
to the patient to ensure ventilation by adapting to the increasing workloads associated with the
disease. In addition, having multiple or alternative tests of respiratory muscle function available
both increases diagnostic precision and makes assessment and follow-up possible in a range of
clinical circumstances.
