What effect does regular exercise have on stroke volume over time?

• A. It decreases
• B. It becomes smaller
• C. It remains unchanged
• D. It becomes larger and more efficient

Answer: (D)

Regular exercise has a significant impact on cardiovascular health, particularly on stroke volume, which is the amount of blood ejected by the heart with each contraction. With consistent and regular exercise, especially aerobic activities, the heart undergoes adaptations that lead to an increase in stroke volume. These adaptations include an increase in the size of the heart, particularly the left ventricle, allowing it to hold more blood. Additionally, regular exercise improves the heart's efficiency, meaning it can pump more blood per beat with less effort. This results in a larger and more efficient stroke volume over time, which is beneficial for overall cardiovascular health and endurance. Furthermore, improved stroke volume contributes to better oxygen delivery to the muscles during physical activity, enhancing athletic performance and supporting overall cardiovascular endurance. As a result, individuals who engage in regular exercise tend to have a stronger and more efficient heart, characterized by an increased stroke volume at rest and during exertion.
