Relationship Between Airway Resistance indices and Maximal Oxygen Uptake in Young Adults
Languages of publication
The present study aims at assessing the relationship between airway resistance indexes (FEV1, FVC and FEV1/FVC) and maximal oxygen uptake (Vo2max) in young adults. Subjects of the study included 50 healthy males (age, 22.1 ± 2.47 years; FEV1, 3.41 ± .66 liter; FVC, 3.96 ± .56 liter; VO2max, 38.83 ± 9.83 ml.kg-1.min-1) studying at Shahid Chamran University of Ahvaz. After determining subjects' volumes of FEV1, FVC and FEV1/FVC by digital spirometer, maximal oxygen uptake was measured. The study protocol measured VO2max levels using the sub-maximal Astrand-Ryming test on the ergometer cycle. The data were analyzed through descriptive and inferential statistics. Results revealed a significant correlation among the three independent variables of FEV1, FVC, FEV1/FVC and projected VO2max values. Based on the results, it can be concluded that these parameters have a close interaction with higher VO2max levels, and therefore, having a lower airway resistance seems beneficial.
