Document Type : original article

Abstract

Purpose: The aim of this study was to survey the agreements between the energy expenditure prediction equations with the criterion model in the exhaustive treadmill test protocols in active young men. Methods: Fifty active young men were selected as subjects (Mean ± SD Age 21.04 ± 2.069 yrs., Height 176.78 ± 4.484 cm, Weight 70.11 ± 5.825 kg) and completed exhaustive treadmill test protocols. Bioenergetical variables during exhaustive protocols using respiratory gas analysis were collected at an interval of ten seconds. To estimate the energy cost and bioenergetical variables, ACSMv, Vander Walt, Pandolf, Léger and Epstein predictive equations for walking and running were considered. Bland-Altman graphical model and Interclass Correlation Coefficient (ICC) statistical tests were used to evaluate the absolute agreement of the methods. Results: The results suggest that the Leger equation for running have high agreement with the criterion model (±1.96; CI = 95% -21.2 to 2.4 ml/kg/min; ICC= 0.89) And ACSM walking and running equations have middle agreement with the criterion model(Walking: ±1.96 ; 95% CI = -8.1 to +4.7 ml/kg/min , ICC= 0.4837 ; Running: ±1.96 ; 95% CI = -27.6 to -3.3 ml/kg/min, ICC: 0.4535). Conclusion: According to study results it could be concluded that the Leger equations for running and relatively ACSM walking and running equations estimating of VO2 among Iranian active young men can be used as an accurate alternative for the criterion method.
