Dependent variables.

All dependent variables and their within subjects factors for the repeated measures ANOVA. The within subjects factor “Test” had two levels: the pretest and the posttest. The within subjects factor “Cylinder” had two levels: the small and the medium cylinder. The between subjects factor for all variables was “Group,” which had two levels: the Breakout-EMG and the Control group. All combinations of interactions, both between the within subjects factors and between the within and between subjects factors, were also tested for effects (see text for details).
