From: Strength training improves heart function, collagen and strength in rats with heart failure
Representative microphotographs of the remote remodeled myocardium stained with eosin–hematoxylin to nuclear volume mensuration (upper pictures) and eosin–picrosirius red for collagen occupied area evaluation (lower pictures). Remodeling parameters included myocyte hypertrophy as estimated by averaged nuclear volume (A) and interstitial fibrosis estimated by % of area occupied by collagen fibers (B) evaluated in the control (C, n = 8), infarcted (MI, n = 10) and infarcted and trained (MIT, n = 10) groups. *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
