Total energy expenditure and rate of energy expenditure (power output) are important considerations for exercise programs and training programs. Mechanical power output generated during competitive lifts in both weightlifting (WL) and powerlifting (PL) is large in magnitude and can be measured accurately using standard biomechanical analysis equipment. Power tests do not appear to have predictive value for performance capability in PL. However, athletes in WL produce power outputs in vertical jump tests that are similar to those they produce in selected phases of the competitive lifts. This fact and related data have led to research that may result in simple power test protocols useful for estimating the training and performance potential of weightlifters and other athletes in power oriented sports, as well as for measuring a power component in standard fitness testing packages. Thus the purposes of this paper are to (a) review what is known about power output during the competitive lifts of WL and PL and the methods used to evaluate it, (b) review what is known about power tests in relation to performance prediction in WL and PL, and (c) suggest applications of this knowledge to related fields of study.
