ABSTRACT

Physical work capacity (PWC) implies the determination of a physical limit of performance. However, the term is used in ergonomics to refer to a physiological limit of human capabilities (as opposed to biomechanical limitations). Thus, PWC is defined as the maximum level of physiological exertion that can be achieved by an individual. The measurement of PWC is generally given in terms of oxygen consumption (e.g. liters of oxygen consumed per min). PWC is used synonymously with aerobic capacity, or VO2max.
