Abstract

"Circuit weight training (CWT) is currently at the forefront of the fitness industry. During the past 10 years, its popularity has increased due to its ability to combat common deterrents of exercise program adhesion. Many individuals that utilize CWT not only use it to fulfill their weekly exercise requirements, but are looking to maintain or lose weight as well. The purpose of this study was to compare the energy expenditures (EE) in total kcals and average rate of perceived exertion (RPE) values of a 20 min CWT protocol and a 20 min steady state aerobic protocol of equivalent intensity based on an individual's average heart rate during the CWT protocol. The CWT protocol consisted of 10 machine weight stations: chest press, leg press, latissimus pull down, shoulder press, hamstring curl, leg extension, assisted pull-up, pec fly, seated row, and back extension. EE was calculated by means of indirect calorimetry by the Cosmed K4 b²© (Rome, Italy) and heart rate (HR) was monitored by means of a FT1 Polar heart rate monitor (Polar Electro, Kempele, Finland). RPE values were taken at the end of every 4th CWT station and every 2 min during the steady state aerobic activity. Paired samples t-tests revealed significant differences in EE and average RPE values during the CWT protocol and steady state aerobic activity. While EE values were greater during the steady state aerobic activity, RPE values were higher during the CWT protocol. These findings add to the limited literature on EE and RPE during CWT and steady state aerobic activity of equivalent intensities"--Leaf iv.
