WebApr 12, 2024 · A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move … WebJul 30, 2024 · At the onset of exercise your muscles signal your heart to pump faster for increased blood flow. In addition, working muscles increase stroke volume by sending higher amounts of blood volume back towards the lungs for oxygen. Therefore, cardiac output rises during exercise due to increased stroke volume and heart rate.
