Abstract

<abstract> <title>Abstract</title> <p> <italic>Purpose</italic>: To investigate whether 12 week inspiratory muscle training (IMT) has any impact on pulmonary function, maximum respiratory pressures and diaphragmatic mobility (DM) in morbidly obese subjects. <italic>Method</italic>: Thirty-one morbidly obese individuals were assessed. Volunteers were randomised into two groups. The IMT group (<italic>n</italic> = 16) followed an IMT protocol for 12 weeks, with a training load of 30% of maximal inspiratory pressure (PImax). The control group (CG) (<italic>n</italic> = 15) followed the same protocol but without inspiratory load. <italic>Results</italic>: A total of 14 subjects performed IMT for 12 weeks. Significant increases in PImax (−86.86 ± −20.70 cmH<sub>2</sub>O versus −106.43 ± −32.97 cmH<sub>2</sub>O, <italic>p</italic> < 0.05) and maximal voluntary ventilation (97.84 ± 37.06 L/min versus 115.17 ± 34.17 L/min, <italic>p</italic> < 0.05) were observed in the IMT group when compared to baseline. However, only FIV<sub>1</sub> significantly differed between the IMT group and the CG after the 12 week protocol (3.35 ± 0.96 L versus 2.22 ± 1.07 L, respectively; <italic>p</italic> < 0.05). No significant differences were found in DM after the IMT protocol was performed. <italic>Conclusion</italic>: IMT improved PImax and altered the FIV<sub>1</sub>. These results suggest that the improvements in muscular respiratory efficiency were insufficient to mobilise the diaphragm and modify ventilation mechanics. Pre-operative IMT may be a valuable approach in obese patients for preventing post-operative pulmonary complications. <ext-link ext-link-type="uri" xlink:href="http://clinicaltrials.org" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">http://clinicaltrials.org</ext-link> -- NCT01449643 -- The Influence of IMT on Diaphragmatic Mobility in Morbidly Obese.<list list-type="bullet"><title>Implications for Rehabilitation <bold>Morbid Obesity</bold></title><list-item><p>Morbid obesity is a disabling condition that has a serious negative impact on lung function, respiratory muscle function and quality of life.</p></list-item><list-item><p>Inspiratory Muscle Training (IMT) is a technique which aims to improve pulmonary expansion and to prevent post surgery complications on morbid obese individuals.</p></list-item><list-item><p>This study shows significantly increased on maximal inspiratory pressure, maximal voluntary ventilation and promoted changes on spirometric variables after IMT.</p></list-item></list></p> </abstract>
