Abstract:

The purpose of this study was to assess the reproducibility of a lifting motion and whether there is a gender difference in terms of a consistent performance. Thirty-four healthy inexperienced males and females performed a lifting task of a load that was 20% of their personal lifting capacity on four separate testing days, while an electromagnetic motion tracking system recorded the lifting motion. All kinematic data were analysed with a mixed two-factor repeated measures multivariate ANOVA (gender × day) design. There were no significant day or gender differences indicating consistency exists in the lifting pattern. It is expected that individuals will adapt their lifting pattern to meet the needs of the lifting task. Given that the pattern was consistent over time for a specific task, it suggests a set motor pattern may be established. This knowledge has implications for work assessment strategies and training programmes.
