| - | The heart, like any muscle, can grow with exercise since it is required to perform at a high level during such activity. The growth of cardiac muscle and simultaneous thickening of ventricular walls has been shown to lead to increased overall perfusion (Burton, Stokes, & Hall, 2004). Additionally, blood returns to the heart using skeletal muscles (which perform better with exercise). Therefore, exercise allows for greater smoothness of the venous blood flow which allows more blood to return to the heart (Lee & Oh, 2016). This allows the heart to pump more blood with each contraction. Higher levels of cardiac output also increase exercise capacity since trained athletes can show up to 40L greater cardiac output than untrained individuals (Lee & Oh, 2016). Lastly, with exercise the heart is able to undergo angiogenesis/coronary collateralization (Gertz et al., 2006). This essentially means that additional vessels are grown and perfuse the heart much better which allows the heart to function better. Specifically, this increases overall perfusion as well as cerebral blood flow which has been shown to improve long-term stroke outcomes (Gertz et al., 2006). | + | The heart, like any muscle, can grow with exercise since it is required to perform at a high level during such activity.
