Effect of different exercise training intensities on age-related cardiac damage in male mice

Metabolic data and cardiac tissue damage in the different groups after exercise training. (A) Quantitative analysis of body weight (0 week and 24 weeks), heart/body weight, LDH, and CK-MB levels in the different groups. n = 8 per group. *P B) Representative photomicrographs of myocardium stained with WGA (green fluorescence) and DAPI (blue fluorescence). (C) Graph showing the cardiomyocyte CSA. (D) H and E staining showing structure damage in cardiac tissue. Magnification 40×. The arrows indicate positively stained cells. n = 3 per group. *P
