Means and standard deviations of the percentage of variance explained by the first 3 PCs (A), and segmental loadings of the dominant forearm, upper arm, trunk, dominant and non-dominant legs on the first 3 PCs during the first (B), last (C), and retention (D) trials. * identifies significant difference between the first trial and the trial where significant changes occurred; #- identifies significant difference between the first and the last trial; §-identifies significant difference between the last and retention trials. The differences are indicated for the PCs loadings coefficients exceeding 0.7.
