WebJan 2, 2024 · It helps improve oxygen supply by increasing how effectively the heart can deliver oxygen, and it develops the peripheral vascular network. It stimulates eccentric cardiac hypertrophy through volume overload of cardiac fibers thus causing them to stretch. This leads to an increase in left ventricular cavity volume. WebThe cardiac output of trained endurance athletes may increase from 5 to 6 L/min at rest to up to 40 L/min during maximal exercise. 73 The heart adapts to this volume load with an increase in internal diameter. Blood pressure also increases during endurance exercise, although to a lesser extent than during strength training. chip or prammer for 2006 acura tl
