Document Summary
Tests strength static ability to exert maximum force isometric force, isotonic force (1-rm), isokinetic tests dynamic capacity to move or maintain the body. Workers are at a higher risk of experiencing a musculoskeletal disorder, when working at their maximum voluntary strength capabilities. Work selection seeks to (cid:515)fit(cid:516) a strong worker into a physically demanding job does not result in the same magnitude of reduction of injuries compared to job design. Muscular strength: as the capacity to produce a force/torque with a voluntary muscle contraction. Do not have the ability to measure the force developed within a muscle, must use the external forces generated between a person and a measurement device. Muscle exertions can be divided into dynamic exertions (produce motion at a joint) or isometric exertions (do not produce motion). Isometric strength: testing isometric strength involve application of a force against a stationary load, standardized procedures have been developed due to simplicity.
