Energy expenditure estimation of a moderate-intensity strength training session

An accurate method for quantifying associated metabolic cost has yet to be developed for a strength training session (ST). The aim of this study was to quantify the energy expenditure (EE) in an ST session composed of eight exercises at moderate intensity using indirect calorimetry and, from the values obtained, develop a prediction equation for estimating EE. Fifteen males (22.9 ± 2.61 years old), with at least 12 months of experience in ST performed one session of strength training composed of 8 exercises. Three sets of repetitions were performed until concentric failure for each exercise at 75% of 1-repetition maximum (75% of 1RM). The model demonstrated that session time and load volume of ST was a significant predictor of EE (p
