Discuss the cardiovascular response to resistance training
The cardiovascular response to resistance exercise is an exaggerated exercise pressor response elicited by the muscle ischemia invoked by the muscle contraction. The increased pressor response causes a pressure overload on the heart. This pressure overload is similar to that which accompanies systemic hypertension and aortic stenosis. Subsequently, the resistance-exercise trained athlete usually has concentric cardiac hypertrophy of the left ventricle, a disproportional thickening of the intraventricular septum and posterior walls without left ventricular chamber enlargement. When the increase in heart mass is normalized for body weight or body surface area, the weight-trained athletes are no different than normal sedentary individuals but have much less cardiac hypertrophy than an endurance-trained athlete.
