Kist WB, Burgess K, Kist SE, Glasheen M, Delp E, KraenzleSchneider J. Comparison of the Sitting-to-Standing Cycle Ergometry versus Treadmill Approach to Graded Exercise Testing on Cardiorespiratory Values in Overweight People with Mild Asthma. JEPonline 2014;17(4):51-71. The purpose of this study was to: (a) determine if standing on a cycle ergometer (Stand CE) increases VO2 max to the equivalent of values obtained by a treadmill (TM); and (b) describe the combined effects of being overweight and having asthma on exercise cardiorespiratory variables. Subjects were overweight people with asthma (OWAS, n = 10) and those of normal weight and normal lungs (NWNL, n = 15). Groups differed (P<0.05) on BMI (OWAS = 27.8 ± 4.5 kg·m-2 , NWNL = 24.8 ± 3.5), FVC (OWAS = 4.0 ± 0.7 L, NWNL = 4.6 ± 0.9), and FEV1 (OWAS = 3.3 ± 0.4 L, NWNL= 3.7 ± 0.7). There were differences by group, but not trial on VO2 max (OWAS: TM = 31.9 ± 6.5 mL·kg-1 ·min-1 , Stand CE = 29.0 ± 6.8, NWNL: TM = 40.2 ± 4.3, Stand CE = 35.9 ± 5.2). This study showed that Stand CE and TM VO2 max values were not statistically different, and that asthma and being overweight had little influence on the exercise cardiorespiratory variables. Differences, when present were due to the OWAS being more deconditioned.
