Objectives: Body plethysmography is a lung function testing method usually applied for determination of thoracic gas volume and airways resistance, but option to measure work of breathing is available in most models. Although the method has been known over fifty years, assessment of work of breathing with it has not yet systematically studied in obesity. The aim of the study was to evaluate the relevance of work of breathing measured by body plethysmography in obese subjects and to compare the results with those of healthy controls and patients with pulmonary diseases of different pulmonary mechanics. Methods: Altogether sixty-two adults were studied prospectively: healthy non-smoking obese subjects (BMI > 30, N = 15), patients with interstitial lung disease (ILD) (N =15), emphysematic COPD (emphysema) (N = 16) and healthy non-smoking controls (controls) (N = 16).
