Data of active tension (A–B) and passive tension (C–D) in response to muscle stretching of the control (C, n = 10), infarcted (MI, n = 9) and infarcted and trained (MIT, n = 9) groups. Bars represent slopes of the linear regressions (B) or growth rate constant of the exponential function (D). In B and D, *p < 0.05 vs. C, by 1-way ANOVA plus Tukey’s post hoc. Symbols and bars represent mean ± SEM
