“The objective of this study was to examine whether a programme of inspiratory muscle training (IMT) improves accumulative distance of self-paced walking in overweight and obese adults.”
“This study indicates that IMT may provide a practical, inexpensive, and minimally intrusive intervention to augment both inspiratory muscle strength and walking distance among overweight and obese adults. The beneficial effects of this treatment were similar to those previously reported from vigorous, supervised training among hospitalised obese patients. Our findings indicate similar effects could be expected without the need for hospitalisation and indicate that IMT via an inspiratory resistance device can easily be performed in the home environment. IMT therefore appears a useful strategy to enhance walking performance in overweight and obese individuals which may prove a meaningful priming intervention with which to stimulate performance adaptations and future engagement with physical activity.”

A new Clinical Study, published in the Journal of Obesity (Volume 2012, Article ID 918202), examined whether a programme of inspiratory muscle training (IMT), using POWERbreathe, improves accumulative distance of self-paced walking in overweight and obese adults.
Fifteen overweight and obese adults were randomised into experimental and placebo groups. Lung function, inspiratory muscle performance, 6-minute walking test, and predicted VO2 max were assessed prior to and following the 4-week IMT intervention.
Both groups performed 30 inspiratory breaths, twice daily using POWERbreathe.
They concluded the study by suggesting that inspiratory muscle training (IMT) provides a practical, minimally intrusive intervention to significantly augment both inspiratory muscle performance and walking distance covered by overweight and obese adults in a clinically relevant 6-minute walk test. This indicates that IMT may provide a useful priming (preparatory) strategy prior to entry in a physical training programme for overweight and obese adults.
