Cardioprotection of EP against high intensive exercise-induced myocardial injury. a Myocardial ischemia/hypoxia detected by HBFP staining. Hypoxic and ischemic cardiomyocytes stained a vivid crimson red color, while the light brown color showed the non-hypoxic and non-ischemic tissue (original magnification ×400). b Quantitative analysis of HBFP staining. The myocardial ischemia/hypoxia density values in Group HE were significantly higher than those in Group C (p < 0.05), while compared with Group HE, the myocardial ischemia/hypoxia density values in Group EEP+HE and Group LEP+HE decreased significantly (p < 0.05). c Alterations of plasma cTnI levels in cardioprotection of EP. The cTnI levels in Group HE were significantly higher than those in Group C (p < 0.05), while compared with Group HE, the cTnI levels in Group EEP+HE and Group LEP+HE decreased significantly (p < 0.05). The data are expressed as the mean ± SD. *p < 0.05 vs Group C, # p < 0.05 vs Group HE
