Figure 2. Longswing amplitude and inter-joint reversal point changes after the practice period.

Results of the 2 (Group)×2 (Time) ANOVA with repeated measures comparing pre- and post-practice skill global index and coordination variables are depicted in (a) longswing amplitude and (b) inter-joint reversal point P2H-P2S. The expert group (E) mean (solid line) and standard deviation (dashed lines) of these variables are provided for comparison. (★) indicates significant group or time differences. Interaction effects are not presented for simplicity.
