Development of biomechanical performance measures in all participants from baseline to retention.

Simulator (S) and on-water tests (W) were quantified in terms of pooled standard deviation (). A significant improvement/degradation in a technical aspect was indicated by values larger/smaller than one, respectively. On-water performance was also qualitatively evaluated by video assessment (V) (−4 to 4 in steps of 1: negative/positive values indicated a performance decrease/increase). Italic bold font: this particular aspect was instructed during training. Empty cells: no video assessment was performed for this technical aspect.
