| Sumario: | The relationship between ratings of perceived physical effort required in human task performance and associated metabolic expenditure was examined in two investigations. In each study, tasks, whose metabolic performance costs were known from the physical work assessment literature, were rated on the effort required to complete the task by subjects who did not know the metabolic information. Results of the first study revealed that personnel specialists (n = 26) could discriminate among tasks of known metabolic differences and that their ratings of the effort required in task performance were highly cor- related with actual metabolic costs. The second study replicated the procedures and results of the first study, using untrained male (n = 26) and female (n = 28) observers and examined sex differences in ratings of perceived effort. No rating sex differences were found beyond the level of chance. Implications of the results are discussed in terms of the development of an assessment index of the physical effort required in task performance. |
