The comparison of dynamic volumes of pulmonary function between different levels of maximal oxygen uptake
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 3
Abstract
Maximal oxygen uptake (VO2max) and pulmonary function may have a close correlation, but few studies have been done in comparison of pulmonary function in different levels of VO2max. The aim of this study was to compare the dynamic volumes of pulmonary function between different levels of maximal oxygen uptake. In order to achieve the purpose of the study, 51 healthy male subjects (age 19-24) participated in this study. After determination of their level of maximal oxygen uptake based on Subjects VO2max levels, they were assigned to A: High (49.76 ml.kg-1.min-1 ), B: mean (39.24 ml.kg-1.min-1) and C; Low (27.51 ml.kg-1.min-1) VO2max groups. The study protocol used in order to measure VO2max level was sub-maximal incremental Astrand–Rhyming test on Ergometr Cycle. The pulmonary function indexes that include Force Expiratory Volume in One Second (FEV1), Forced Vital Capacity (FVC), and FEV1/FVC were measured by digital spirometry. The data were analyzed through one way analyze of variance (ANOVA). Results showed that there was significant difference between FEV1, FVC and FEV1/FVC in different levels of VO2max (p<0.001). Based on the results, it can be concluded that dynamic variables of pulmonary function are associated with VO2max levels, and can limit aerobic capacity.
