Influence of Resistance Training Variables on Excess Postexercise Oxygen Consumption: A Systematic Review

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 20 ± 2 and 34 ± 14 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.
