Study Notes
Exercise Physiology and Cardiovascular Adaptations
- Static exercise involves muscle contraction with occluded blood vessels, leading to a delayed increase in blood flow until muscle relaxation
- Dynamic (aerobic) exercise results in a greater increase in heart rate and volume load compared to static (pressure load) exercise
- Females have higher cardiac output and heart rate, but lower stroke volume than males at the same absolute work rate
- Children have smaller cardiac output and stroke volume, while elderly individuals have higher heart rate and blood pressure at the same absolute work rate
- Endurance training increases the size, volume, and mass of the heart, leading to increased blood filling capacity and muscle size
- Athletes develop an "athlete's heart" characterized by cardiac hypertrophy, bradycardia, and increased stroke volume
- Cardiac output remains mostly the same for trained and untrained individuals, but trained individuals have higher cardiac output at maximum due to a larger heart and stroke volume
- Trained athletes have a larger stroke volume, allowing for a lower heart rate to maintain the same cardiac output
- Trained individuals have lower heart rate, increased muscle mass, and psychological factors that allow them to reach a higher heart rate during exercise
- Arteries respond to aerobic training with increased diameter, improved responsiveness, and endothelial functioning, leading to better blood flow regulation
- Capillarization and angiogenesis increase with training, resulting in more capillaries and blood volume, with a subsequent increase in red blood cells
- Baroreceptors in the arteries sense pressure and try to regulate cardiac output and resistance, resulting in changes in total peripheral resistance and mean arterial pressure during exercise
