Abstract
Job analysis has shown that many tasks in the energy industry are physically demanding. This study examined the validity of an isometric strength test battery for predicting performance in work sample tests that simulated physically demanding tasks in coal mining and oil production. Since two of the work sample tests involved an endurance component, metabolically determined VO(2) (L/Min) was used to measure arm endurance. All tests were administered to 25 male and 25 female physically fit subjects. Correlations between the isometric strength tests and the work sample tests ranged from .67 to .93. In addition, the isometric strength tests were more highly correlated with the endurance work sample tests than metabolically measured arm endurance. Slopes and intercepts of the male and female regression lines were homogeneous. These results support the validity of isometric strength tests for predicting performance in physically demanding jobs.
