Perhaps surprisingly, the nature of the between-rower coordination appeared to change as average CRP (Figure 7) evolved from -0.30 ± 4.44° (pre-CT) to -4.09 ± 3.86° (post-CT), d = 0.91, suggesting the coming to the fore of a phase lag of the stroke with respect to the bow rower. This evidence concerns the gene CRP and Stroke.
