Effect of regular exercise on cardiomyocyte cross-sectional area in ovariectomized (OXV) rats. Stained images are transverse sections of cardiomyocytes at ×400 magnification from the hearts of sham-operated controls (SHAM) and OXV rats with no further treatment (OXV), with estrogen supplementation (OVX + E2), or with exercise training (OVX + Ex). Only myocytes with a nucleus, a clear cell boundary, and a round or rectangular shape (length:width <1.5) were collected. Box plot of cross-sectional area of cells from the Sham-operated (control) group (SHAM) and from the three treatment groups of OXV rats (+oil, +E2, +EX). Top and bottom of box Minimum and maximum levels of cell cross-sectional area, horizontal line within the box median. Data are from 6–7 hearts in each group (150 cells per heart). Asterisk and hash symbols Significant difference (P < 0.05) from SHAM and OVX rats, respectively, using the Student–Newman–Keuls test after analysis of variance (ANOVA)
