[Physical workload demands: the combined use of 2 evaluation programs].
A computerized methodology is presented for the "on-site" evaluation of work-related physical activities in industrial plant workers. Subjects were videotaped during the activities while heart rate and subjective perception of effort were monitored. The videorecordings were then analyzed with two appropriate software, in order to identify activities at high risk for musculoskeletal injuries ("Vision 3000" program, Promatek Ltd., Montreal) and to evaluate energy expenditure ("Energy" program, University of Michigan). Validation of the energy expenditure indirect analysis system was done by monitoring oxygen consumption (VO2) with a portable telemetric oxygen uptake analyzer ("K2", Cosmed, Rome). No statistically significant differences were found between direct measurements of VO2 and laboratory-derived estimates of energy consumption. The utilization of these two software provides a fast and reliable profile of job requirements and associated risks of musculoskeletal injury.
