摘要：Background and objectives: Finding an appropriate method for measuring maximum aerobic power (ormaximal oxygen consumption, VO2max) and replacing this method with conventional maximal exercise teststo obtain VO2max can be useful in many cases. The measurement of cardiorespiratory functional capacity hasalways been of great importance to both normal people and elite athletes. The cardiorespiratory system isone of the determinants of health and should be kept wholesome by people to maintain their well-being.Accordingly, the present study was conducted to design the allometric equations special for Iranian men toassist in the accurate assessment of VO2max in individuals without the need for maximal exercise tests.Materials and methods: This experimental and correlational research was conducted on 44 Iranian malevolunteers aged 18-25 years with mean age of 20.5 ± 1.73 years, mean weight of 71.6 ± 10.84 kg andmean height of 176 ± 6.3 cm. After calculating the anthropometric characteristics of the subjects, theirVO2max index was measured using the direct measurement of respiratory gases for designing the allometricequations with the aid of regression analysis. Results: The findings showed that there is a relatively goodrelationship between the designed allometric equations (VO2max=1.04×weight0.03, VO2max=-0.55×(BodySurface Area) BSA1.84, VO2max=0.83×(Lean Body Mass) LBM0.05) and the direct measurement of respiratorygases (SEE=0.31-0.32 R=0.67-0.70), and we can use these equations with great confidence to measureVO2max. Conclusion: Considering that the VO2max measurement is of particular importance to individuals,we have been able to assess the VO2max using allometric equations designed for Iranian men with a fairlygood validity and that since the VO2max measurement of individuals without the need to perform themaximal exercise tests can be useful in many situations, so it is recommended to use our allometricequations designed for Iranian men to measure their VO2max.
