MAP20071024434Development of factor-score-based models to explain and predict maximal box-lifting performance / J. Stevenson... [et al.]Sumario: The purpose of the present study is to develop factor-score-based models to predict maximum mass on a box-lifting task from data obtained during isoinertial lifting on an "incremental lifting machine", and to compare predictive and explanatory powers of factor-score-based models to models derived form data-level variables. The implications of these findings for ergonomic research and practical problem-solving situations are also presentedEn: Ergonomics. - London and Washington. - Vol. 38, nº 2, February 1995 ; p. 292-3021.
