Final answer:
The recommended volume of aerobic exercise to reduce blood pressure is 150 minutes or more per week. This exercise should be moderate to vigorous in intensity, spread throughout the week, and as little as 30 minutes daily can provide significant cardiovascular benefits. The correct option is 2.
Step-by-step explanation:
The volume of regular aerobic exercise that has been shown consistently to reduce systolic and diastolic blood pressure is 150 minutes per week or more. It is important to spread this exercise throughout the week for substantial health benefits.
According to the U.S. Department of Health and Human Services (HHS), adults should aim for at least 150 minutes of moderate-intensity aerobic activity, or 75 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of both.
Engaging in at least 30 minutes of noncontinuous exercise each day can also have beneficial effects on cardiovascular health, including lowering the risk of heart attack by nearly 50 percent. While factors like diet and avoiding smoking are critical, moderate exercise is clearly beneficial for maintaining vascular homeostasis and can lead to improved health and longer life expectancy.
