Abstract

Energy expenditure is usually estimated by total oxygen uptake. However, with weightlifting, very little oxygen is utilized during the lift. The majority of oxygen uptake happens during recovery (Excess Post-Exercise Oxygen Consumption, EPOC). The purpose of this study is to determine the significance of the anaerobic and EPOC phases during weightlifting exercises in estimation of total energy cost. We gathered data from 42 subjects (60 averaged trials) aging between 18 and 35 years. Each subject chose a comfortable weight and lifted to a cadence of 1.5 sec up and 1.5 sec down. Tests were given on two different occasions. We used a metabolic cart to collect oxygen consumption (VO2), and EPOC measurements. Blood lactate measurements were taken to estimate anaerobic energy costs. Our data revealed that the contribution of anaerobic and EPOC phases, had the most significant impact on the total energy cost estimation.
