Background: Studies reported conflicting results about the relationship between anthropometric factors, respiratory exchange Ratio, energy expenditure and VO2 max. Therefore the aim of this study was to investigate the relationship between anthropometric factors, respiratory exchange ratio and energy expenditure with VO2 max in sedentary men.
Materials and Methods: Thirty one sedentary healthy men (23.67±2.45 years old age, BMI=22.49±1.58 kg/m2) volunteered for participation this study. After the measurement of anthropometric factors, subjects performed an acute endurance exercise on the ergometer for determination of VO2 max. Subjects performed major protocol, one hour cycling on ergometer via 70% VO2 max for the determination of the respiratory exchange ratio and the rate of energy expenditure, 72 hours later.
Results: The results of this study showed that there is not any significant relationship between VO2 max and anthropometric factors, respiratory exchange ratio and energy expenditure. Also, regression analysis indicated that all these variables cannot predicate the VO2 max.
conclusion: According to the results of this study anthropometric factors, respiratory exchange ratio and energy expenditure are not strong predictors of VO2 max in sedentary young men.
