%X Objectives. Resistance training may influence the resting metabolic rate (RMR), which is desirable in weight management programs. However, its impact on excess postexercise oxygen consumption (EPOC) is yet to be defined. The study evaluated the contribution of resistance training variables to EPOC. Design. Studies published until November 2011 were systematically reviewed. Methods. MEDLINE, LILACS, SCIELO, Science Citation Index, Scopus, SPORTDiscus, and CINAHL databases were consulted. The methodological quality of studies was assessed by the PEDro 10-point scale. A total of 155 participants (54% men) aged between and years were observed by 16 studies (quality scores ranged from 5 to 7), which were organized according to treatment similarity (number of sets, intensity, rest interval, speed of movement, and exercise order). Results. Training volume seemed to influence both EPOC magnitude and duration, whereas workload influenced mostly the magnitude. Short rest intervals (<60£¿s) increased the EPOC magnitude, but not the overall energy expenditure. Conclusion. Resistance training with high intensity and volume, performed with short rest intervals (as in circuit training), probably have greater impact on EPOC. Methodological procedures, particularly time of post-exercise observation and RMR assessment, should be standardized to an appropriate quantification of the actual influence of resistance training on EPOC. 1. Introduction In the recovery period after exercise there is an increase in VO2 termed the ¡°excess postexercise oxygen consumption¡± (EPOC). The EPOC represents the number of calories expended (above resting values) after an exercise bout. The EPOC effect is greatest soon after the exercise is completed and decreases over time. Aerobic training is considered as the most effective exercise to increase energy expenditure (EE) and EPOC [1], but resistive training (RT) has been also shown to have a favorable impact [2¨C7]. It is accepted that during recovery the EPOC goes along with greater fat burn, which is a desirable effect to weight loss purposes [3, 8]. Although some studies have suggested that the contribution of RT to increase EE would be due to the exercise session alone [8, 9], others indicated that a higher oxygen uptake (VO2) after the end of exercise would also play an important role [5, 10]. The possible contribution of RT to EPOC has been therefore investigated [10¨C19]. The available research suggests that RT may elicit a valuable EPOC to weight management¡ªsome studies have even found significantly greater EPOC response after RT
