LV, left ventricle; RV, right ventricle; EF, ejection fraction.
Table 3: Regression coefficients for linear regression model to determine whether testosterone and/or resistance training were significant predictors of changes in cardiac mass or contractility variables. Primarily, LV and RV mass increased with testosterone, while ejection fractions increased with resistance training.
