Abstract

Objective: To examine the efficacy of inspiratory muscle training (IMT) as a non-intrusive and practical intervention to stimulate improved functional fitness in adults with obesity. As excess adiposity of the chest impedes the mechanics of breathing, targeted re-training of the inspiratory muscles may ameliorate sensations of breathlessness, improve physical performance and lead to greater engagement in physical activity. Methods: Sixty seven adults (BMI = 36 ±6.5) were randomized into either an experimental (EXP: n=35) or placebo (PLA: n=32) group with both groups undertaking a 4-week IMT intervention, comprising daily use of an inspiratory resistance device set to 55% (EXP), or 10% (PLA) of maximum inspiratory effort. Results: Inspiratory muscle strength was significantly improved in EXP (19.1 cmH20 gain; P<0.01) but did not change in PLA. Additionally, the post training walking distance covered was significantly extended for EXP (P<0.01), but not for PLA. Bivariate analysis demonstrated a positive association between the change (%) of performance in the walking test and BMI (r = 0.78; P<0.01) for EXP. Conclusion: The findings from this study suggest IMT provides a practical, self-administered intervention for use in a home setting. This could be a useful strategy for wider scale public health implementation and concurrent application of physical activity initiatives.
