National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Muscle Overexertion During Repetitive Lifting.

PB2013106552

Publication Date	2005
Personal Author	Marras, W. S.; Ferguson, S. A.; Burr, D. L.; Parakkat, J.; Chany, A. M.; Yang, G.
Page Count	157
Abstract	The findings from each level of analysis, when considered collectively, provide profuse evidence of the complexity of spinal loading investigations and the factors that can greatly influence LBP risk. Throughout the analyses, there was a recurrent finding illustrating the difference in the development of motor control programs between workers with no experience and workers with years of experience. First brought to our attention was the fact that novices reported much higher levels of discomfort than their experienced counterparts, even though the spinal loading due to the continuous task was not as highly different between the two groups. The spinal loading resulting from the continuous task also indicated that there may be a certain lift frequency at which people are used to lifting.
