Low back loading during lifting on a ship
conference paper
The aim of this study was to find out how timing can affect low back loading during lifting on a ship. Accelerations were measured onboard of a frigate at a moderate sea-state. Those accelerations were applied to an inverse dynamic analysis (using a full-body 3D linked segment model) of lifting movements that had been recorded in the laboratory. It was found that ship accelerations up to an RMS level of 0.68 m/s 2 have little influence on the extending and total low back moment. However, twisting moments may, depending on sailing direction, location on the ship, and subject orientation relative to the ship, be increased by over 50 % when the lifting movement is initiated at the wrong instant.
