Objective: Cough is a biological defense mechanism which produces sputum. Difficulties with expelling sputum can occur during decreased coughing ability caused by obesity, which increases the risk of pulmonary complications.We investigated the influence of an 8-week inspiratory muscle training (IMT) program on respiratory function and respiratory muscle strength in the sitting and supine positions of people with obesity. Design: A randomized controlled trial Methods: The participants were Twenty-one men with a body mass index (BMI) ≥ 30 kg/m2 or more. They were randomized into a control group (CG: n=10) and an IMT group (IMTG: n=11). The threshold IMT was used at a load of 30% of the maximum inspiratory oral pressure in the IMTG; the minimum load of the threshold IMT was used in the CG. Two sets of 15 min a day were performed four times a week for 8 weeks. Respiratory function, respiratory muscle strength, and coughing ability were measured in the sitting and supine positions. Results: Compared to baseline values, vital capacity in the supine position and inspiratory and expiratory muscle strength were significantly increased after 8 weeks in the IMTG, but not in theCG.Coughing ability did not differ significantly between the groups. Conclusion: Eight weeks of IMT enhanced respiratory muscle strength in men with obesity and improved vital capacity in the supine position;however, itdid not improve coughing ability.
