Background and Objectives:Role of the BODE index (including BMI, FEV1, exercise capacity and dyspnea elements) has been detected for predicting in the morbidity, survival, hospitalization and development period or as a respiratory rehabilitation intermediate evaluation. However its role is not clear in chronic obese asthmatic patients with respect to fitness profile (i.e.  VO2/HR,  VO2/WR, VO2 peak and 6 min-walking distance).
Subjects and Methods: Tewenty seven middle–aged men (33–54 rang ys) with a mild and moderate asthma, demographic value of BMI (31.3 ± 2.6 kg/m2) and functional capacity 2.7±0.43L/min were voluntarily participated. Legion level and DSI were determined by a NYHA guidelines, as well pulmonary capacities and fitness profile including VO2/HR,  VO2/WR, VO2 peak and 6 min-walking distance) were evaluated by a Knudson style and YMCA’S protocol respectively. The six–min walking test performed according with an ATS recommendation and BI was calculated using the Celli’s scale.
Results: Spirometric variables (ie, FVC%, FEV1%, FEV1/ FVC, PEF% , FEF25%- 75% ) and fitness indexes with BI score were not significantly corrected; but baseline FFV1% value had markedly association with a  (VO2/WR ),( r = 0.39, P= 0/045 ).
Conclusion: it seems that BI score as a validation scale are not suitable for the selected aerobic or respiratory indexes evaluation in asthmatic patients. Meanwhile, we need emphasize experimentally on BI elements cross-validation, and unique variables placement or a BI score modification in the large obese population spectrum with a chronic bronchial asthma disease
