Metabolic responses to strength training: an emphasis on energy expenditure.

The present study reviews the results reported in the literature regarding energy expenditure in strength training (ST). For this purpose, a search was conducted in the Medline and Sport Discus databases using the following key words: strength training, energy expenditure, and excess post-exercise oxygen consumption (EPOC). The studies analyzed report that ST protocols involving exercises for the major muscle groups characterized by high-intensity and high-volume training and low resting intervals between sets and exercises have a greater metabolic impact on ST. These variables also interfere with the magnitude and duration of EPO
