Relationship Between Airway Resistance indices and Maximal Oxygen Uptake in Young Adults

Abstract

Relationship Between Airway Resistance indices and Maximal Oxygen Uptake in Young Adults 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.

“…The result of this study shows that between amounts of FVC with peak oxygen consumption has a positive significant correlation. The findings from the present study are consistent Fatemi et al [3] and Rabiee et al [17]and inconsistent Haji Nia et al [8] with those reported in the literature.…”

“…Fatemi et al [3] reported that a significant correlation among the three independent variables of FEV1, FVC, FEV1/FVC and projected VO2max values in 50 healthy males with range of age, 22.1 ± 2.47 years. Rabiee et al [17] investigated the Relationship between body composition and maximum oxygen consumption with pulmonary function in 20 subjects show that there was a significant positive correlation between Cardio respiratory fitness and respiratory parameters in light weight in the FEV1 and FVC and heavy weight groups in the FEV1 and FVC.…”

“…Measurement of respiratory indices will provide useful information about the effect of aerobic exercise on the strength of respiratory muscles, airway resistance, and lung function. Dynamic respiratory indices such as forced vital capacity (FVC) and forced expiratory volume in first second (FEV1) depend on the factors such as age, level of physical activity, body composition, and health condition of people [3].…”

“…(Mehrotra et al, 1998;Mazica et al, 2015;Adegoke & Arogundade, 2002;Bilgin, Çetin, & Pulur, 2010 ). Some studies have suggested the significant positive relationship between aerobic capacity and pulmonary function tests (Harries, 1994;Bilgin et al, 2010;Fatemi & Ghanbarzadeh, 2010;Chaitra, Pandurang, Nagaraja, & Vijay, 2011). The significant improvement in the pulmonary functions have been found in endurance trained athletes: swimmers (Mehrotra et all., 1998;Nilesh et al, 2012), basketball and water polo players, rowers (Mazica et all., 2015), cyclists, middle and long distance runners (Harries, 1994).…”

“…Many authors have proved the correlation between the possibilities of the respiratory system and aerobic capacities of the sportsmen (Bilgin et al, 2010;Fatemi & Ghanbarzadeh, 2010;Chaitra, Pandurang, Nagaraja, & Vijay, 2011;Harries, 1994). Many observations have shown that in some sports the result is to the great extent determined by aerobic capacities of the sportsmen.…”
