Panel A: effect of increasing pause durations on the relative contraction (post-rest contraction divided by previous twitch of tension) of the control (C, n = 10), infarcted (MI, n = 9) and infarcted and trained (MIT, n = 8) groups. Panel B: area under curves calculated from the sided graphic. In A, *p < 0.05 vs. C. ^†p < 0.05 vs. MI, by 2-way ANOVA plus Tukey’s post hoc. In B, *p < 0.05 vs. C. ^†p < 0.05 vs. MI, by 1-way ANOVA plus Tukey’s post hoc. Symbols and bars represent mean ± SEM
