MAP20071019325Gagnon, MichelineBiomechanical exploration on dynamic modes of lifting / Micheline Gagnon and Gilmen SmythSumario: The specific objectives were the determination of the dynamic effects on joint loadings which included different velocity-acceleration patterns and different techniques referring to inclusion or omission of pauses in the movement. Two statistical null hypotheses were tested to examine (1) if there were differences in the execution processes between a slow-continuous lift, and (2) if there were differences in the execution processes between an accelerated-continuous lift and accelerated lift interrupted with a pauseEn: Ergonomics. - London and Washington. - Vol. 35, nº 3, March 1992 ; p. 329-3451.
