How does regular aerobic exercise typically affect resting blood pressure?

1. It increases resting blood pressure

2. It has no effect on resting blood pressure

3. It decreases resting blood pressure

4. It fluctuates resting blood pressure

The correct answer is: It decreases resting blood pressure

Regular aerobic exercise is known to have a beneficial impact on cardiovascular health, including effects on resting blood pressure. Engaging in consistent aerobic activities, such as running, cycling, or swimming, enhances the efficiency of the heart and blood vessels. This improvement in cardiovascular function often leads to a decrease in both systolic and diastolic blood pressure at rest. The reduction in resting blood pressure can be attributed to several mechanisms. Aerobic exercise contributes to the heart's ability to pump blood more efficiently, which means that for the same amount of work, the heart does not need to exert as much force, resulting in lower blood pressure. Additionally, regular training may improve vascular function and promote adaptations in the arterial wall, making it more compliant and reducing resistance to blood flow. Consequently, individuals who engage in regular aerobic exercise can often experience a significant drop in their resting blood pressure, providing protective effects against hypertension and associated cardiovascular diseases. This is why the option indicating a decrease in resting blood pressure is the most accurate assessment of the effects of regular aerobic exercise.
