Abstract
An isometric supination experiment was performed during which the subjects average integrated biceps electromyography and pulmonary ventilation were measured as indicators of work stress. The significance of both myogram height and pulmonary ventilation as indicators of physiological work stress was tested by regression analyses and analysis of variance with both torque and time as independent variables. A high degree of correlation was noted in all cases between electromyograph height and torque levels. In no case was any significant correlation found between pulmonary ventilation and either torque or time. The results of this study indicated that electromyographic techniques are more reliable as indicators of occupational work stress than are measurements of pulmonary ventilation, in situations where small muscle groups perform the task under study.
