(a) Difference in m. anconeus onset, AOL-R, between forelimbs for each treatment. (b) For roll hops, the difference in m. anconeus onset between forelimbs, AOL-R, versus time difference between forelimb touchdown (TDL-R) colour coded by animal. (c) Difference in normalized pre-landing EMG activity between forelimbs, AIL-R. (d) For roll hops, the difference in normalized pre-landing EMG activity between forelimbs, AIL-R, versus the time difference between forelimb touchdown, TDL-R, colour coded by animal. Linear regression lines for each animal are included for significant relationships with non-zero slopes.
