Use of Anthropometry and Dynamic Strength in Developing Screening and Placement Procedures for Workers

Abstract

Pre-employment strength testing is an important tool by means of which a proper match between job demands and worker’s capacity can be achieved. Until very recently worker strengths utilized in such matching were isometric (static). Since most jobs are dynamic in nature, it is preferable that dynamic (isotonic) strengths be used. This paper describes the prototype of a dynamic strength equipment and demonstrates its effectiveness. The experimental data collected shows that simulated job dynamic strengths (SJDSs) are better means of estimating physical demands of manual lifting and carrying activities. Preliminary screening models, based on SJDS, are also proposed.
