Effects of prolonged driving on an occupational lifting task performance

This study evaluated the lifting kinematics and muscle activation for an occupational lifting task before and after a three-hour simulated driving task. No changes in upper body lifting kinematics were found however, there were significant differences in maximum and mean percent muscle activation levels when compared to their 100% maximum voluntary contraction. The implications of this study could be an indicator of injury risk for personnel working in occupations requiring physically demanding work following long driving periods, such as emergency medical services, long-haul truck drivers and professional movers.
