Human physical strengths are frequently measured by ergononists in order to properly match workers and jobs. Measurement of physical strengths by physical therapists, to determine the extent of recovery after injury, is also very common. The strengths measured in such cases, until very recently, have been static (isometric). Most jobs, however, are dynamic and, therefore, the measurement of inertial (dynamic) component is essential to correctly estimate physical strength exertion capabilities of individuals. The work described in this paper supports this argument.
