Does exercise make heart bigger? Regular cardiovascular exercise makes your heart more efficient at pumping blood to your body. In the case of athletes who do a lot of very high-intensity training, the heart sometimes actually gets a little bigger.
What cause the heart to enlarge? High blood pressure. Your heart may have to pump harder to deliver blood to the rest of your body, enlarging and thickening the muscle. High blood pressure can cause the left ventricle to enlarge, causing the heart muscle eventually to weaken. High blood pressure may also enlarge the upper chambers of your heart.
Does running enlarge your heart? Clearly, long-term running changes your vascular system; your heart size grows, the heartbeat rate decreases and your arteries widen.
