Immediate and Short-Term Effects of a Single Bout of Circuit Resistance Training and Tabata-Style Resistance Training on Excess Post-Exercise Oxygen Consumption in Resistance-Trained Individuals

Increased energy expenditure due to post-exercise oxygen consumption may be a valuable tool in maintaining health and preventing obesity. Circuit resistance training and Tabata-style resistance training have potential to increase daily energy expenditure in a time-efficient manner. The purpose of this study was to compare the excess post-exercise oxygen consumption immediately following and 24 hours after a single bout of circuit resistance training and a single bout of Tabata-style resistance training. Nine participants were recruited and randomly assigned a completion order of the control, circuit resistance training, and Tabata-style resistance training conditions. Resting energy expenditure were measured at baseline, immediately following each condition, and 24 hours after each condition to evaluate differences related to time and condition. One-way repeated-measures ANOVA was used to evaluate differences between resting energy expenditure at baseline and at the time points of immediately following and 24 hours after participation in circuit resistance training and Tabata-style resistance training. A paired samples t-test was used to determine if there was a difference in the EPOC elicited immediately following circuit resistance training and Tabata-style resistance training. Data analysis suggested that resting energy expenditure was significantly increased immediately following both protocols but not at 24 hours after cessation of exercise. Analysis also indicated that there was not a statistically significant difference in the elevation of energy expenditure due to EPOC immediately after the protocols.
