The energy consumption during anaerobic exercises

This study explores the concept of ergogenesis and analyzes how different training variables influence energy expenditure (EE) during resistance training exercises. Traditionally, oxygen uptake (VO2) has been the primary method used to estimate the energy cost of resistance exercise (RE). However, recent research suggests that a more comprehensive approach—incorporating aerobic metabolism, excess post-exercise oxygen consumption (EPOC), and anaerobic energy expenditure—provides a clearer understanding of how these factors interact both during and after resistance training. Studies on ergogenesis underscore the crucial role of anaerobic metabolism, especially during rest intervals between sets and throughout the recovery phase after training sessions. While anaerobic energy expenditure is predominant during the exercise itself, it significantly contributes to the overall energy expenditure, providing a deeper understanding of the metabolic impact of resistance training. This review synthesizes findings from various studies that consider VO2, EPOC, and anaerobic energy expenditure to better understand how training variables—such as intensity, volume, and reaching muscle failure—affect the total energy expenditure of resistance training. By examining these interactions, this study offers insights to optimize training strategies and enhance performance outcomes for athletes and fitness enthusiasts.
