Abstract

ABSTRACT: Purpose : Peripheral heart action (PHA) is a style of circuit training that alternates upper and lower body resistance exercises with minimal rest between sets. The purpose of this study was to compare the metabolic demands of PHA to traditional hypertrophy training (TRAD) and to provide between sex comparison for both types of resistance training (RT). Methods : Twenty resistance-trained individuals underwent two bouts of volume-load matched RT: PHA and TRAD. We measured oxygen uptake (VO2 ), heart rate (HR), blood lactate (BL) concentration, rating of perceived exertion (RPE), excess post-exercise oxygen consumption (EPOC), and duration of each session. Results : PHA elicited significantly greater %VO2 max ( p < .001), %HRmax ( p < .001), RPE ( p < .001), and EPOC ( p < .001) compared to TRAD. PHA was also completed in less time ( p < .001). Compared to TRAD, BL was significantly higher at mid-exercise ( p < .001), post-exercise ( p < .001), and 5-min post-exercise ( p < .001) during PHA. There were no between-sex differences for BL at any time-point for TRAD. However, during PHA, BL was significantly higher for males at mid-exercise ( p = .04), post-exercise ( p = .02), and 5-min post-exercise ( p = .002). No between-sex differences were detected for HR, VO2, RPE, or duration for either style of RT. Conclusions : PHA is a time-effective and metabolically demanding circuit that may lead to strength and cardiorespiratory adaptations. Males produced more BL than females during PHA, but not TRAD, suggesting that they incurred more metabolic stress during the bout of circuit training.
