Does physiological concentric left ventricular hypertrophy in strength-trained individuals enhance the inotropic response to dobutamine compared to sedentary subjects?
Concentric left ventricular physiological hypertrophy in resistance-trained individuals is associated with enhanced inotropic but attenuated chronotropic responses to catecholamines.
Suman et al. (2000) studied this question.
