Figure 2

Operating lung volumes during constant workrate cycle exercise expressed as a % of predicted total lung capacity according to body mass index categories. Panel A shows end-inspiratory lung volume (EILV) and panel B, end-expiratory lung volume (EELV). Data points represent mean values at baseline, 25%, 50%, 75% and 100% of constant workrate endurance time. Values are mean ± SE. White filled circles are normal BMI, grey are overweight and black, obese patients. Horizontal lines represent total lung capacity for normal BMI (NBMI), overweight, (OW) and obese (OB) patients. * = p < 0.05; † = p < 0.005; ‡ = p < 0.01.
