The static load component in muscle work.
By citing examples from actual work situations and discussing the concept of muscular endurance and fatigue this paper is intended to provide an account of past and current research on the "static" component of muscular load during work. By amplitude probability distribution analysis of electromyographic signals it is possible to estimate the "static level" of muscular load during work. Electromyographic studies of job rotation between different assembly tasks in electronic industries often show that there are quantitatively and qualitatively only small differences in muscular load between different tasks.
