Microstructure of the myocardium using an optical microscope in each group of rats (HE ×400). (a) The control group, (b) the exhaustive exercise group, (c) the low-intensity exercise preconditioning + exhaustive exercise group, (d) the middle-intensity exercise preconditioning + exhaustive exercise group, and (e) the intense exercise preconditioning + exhaustive exercise group. n = 8 per group. (A) The arrow shows myocardial rupture. (B) The arrow shows myocardial cell edema and inflammatory infiltration. (C) The arrow shows myocardial hyperplasia and edema.
