Effect of acute and chronic pressure-threshold inspiratory muscle training on upper and lower airway function

How, Stephen Christopher January 2010 (has links)
There is evidence to suggest that inspiratory muscle training (IMT) may influence the functional properties of the muscles of the upper (UA) and lower (LA) airway. However, the nature and functional relevance of this influence is currently unclear. This thesis examined the effect of acute and chronic IMT in the context of UA and LA function. The ability of IMT to activate the UA dilator muscles, genioglossus (GG) and geniohyoid (GH), was examined using magnetic resonance imaging (MRI), as was the effect of chronic training on these muscles. In addition, the effect of acute and chronic IMT upon LA resistance (Rrs) and function was investigated in people with asthma using the Forced Oscillation Technique and conventional spirometry. For the UA, an acute bout of IMT at 60% maximal inspiratory mouth pressure (MIP) resulted in significant GG and GH activation (P < 0.001) as demonstrated by increases in the transverse relaxation time of muscle water (T2). Despite this, MRI was unable to detect any effect of chronic IMT upon UA function. For the LA, the usual increase in Rrs, following deep inhalation (DI) in people with asthma was attenuated with both single and multiple breaths against a pressure-threshold load equal to 50% MIP. However, six weeks IMT had no effect on baseline airway function or response to DI. In conclusion, an acute effect of pressure-threshold IMT upon UA and LA function was demonstrated. A strong rationale for a beneficial influence of chronic pressure-threshold IMT was therefore demonstrated. However, the data were insufficient to either reject, or accept the hypothesis that IMT exerts more than a transient influence upon UA and LA function, but insights are presented that support the need for further investigations.
