CASTINHEIRAS NETO, Antonio Gil; SILVA, Nádia Lima da and FARINATTI, Paulo de Tarso Veras. Influence of resistance training variables on post-exercise oxygen consumption: a systematic review. Rev Bras Med Esporte [online]. 2009, vol.15, n.1, pp. 70-78. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922009000100015.
Resistance training (RT) may influence resting metabolic rate (RMR) increase. There is a consensus that the volume of the RT session may produce higher caloric expenditure and that the excess post-exercise oxygen consumption (EPOC) may vary according to the characteristics of the exercise program. However, it is not possible yet to define which prescription variables have greater impact on the EPOC. The aim of the present study was to systematically review the studies that investigated the relationship between EPOC and training variables. A total of 17 studies were selected, being organized according to treatment similarity (number of sets, intensity, rest interval, speed of muscle contraction and exercise order). Descriptive statistical techniques were used to establish possible tendency in dose-response relationships. Subsequently, data were qualitatively analyzed. The available evidence suggested that a short rest interval and the circuit training prescription mode had the greatest impact on the EPOC magnitude. As for the other variables, it was not possible to establish any tendency due to methodological limitations, especially concerning EPOC duration. In addition, it seems to be necessary to standardize important aspects of the EPOC assessing, such as the period of observation after exercise and criteria for measuring RMR.
