520  ‎$a‎The objective of this study was to determine the degree to which the spine is overloaded during unexpected loading. In order to quantify this over-response, the following components of the trunk muscle action were investigated: (1) the average relative magnitude of muscle force, (2) the peak force exerted by the muscle, (3) the onset of muscle force development during the exertion, and (4) the time duration of the muscle force. These component were investigated as a function of both sudden expected and sudden expected and sudden unexpected load handling
