Question 15

Swimming laps is the recommended vigorous activity.

Swimming laps provides an excellent cardiovascular workout while being low-impact, making it suitable for overweight, middle-aged individuals at risk for cardiovascular disease.

A) Taking a long brisk walk

While taking a long brisk walk can be beneficial for general fitness, it may not qualify as vigorous activity sufficient for improving cardiovascular health in someone with increased risk. Walking typically involves a lower intensity compared to swimming laps, which engages multiple muscle groups and elevates heart rate more significantly.

B) Going on a casual bike ride

A casual bike ride might not provide the intensity needed for vigorous exercise. Although cycling can be beneficial, if done at a leisurely pace, it may not produce the cardiovascular benefits required for someone with an increased risk of heart disease.

C) Swimming laps

Swimming laps is ideal as it constitutes vigorous activity that strengthens the heart and lungs while being gentle on the joints. This makes it a safe and effective choice for someone who is overweight and at risk for cardiovascular issues, allowing for a comprehensive workout that enhances endurance and cardiovascular fitness.

D) Raking leaves

Raking leaves, while it does involve physical activity, is generally not considered vigorous exercise. It may not elevate the heart rate to the extent needed for significant cardiovascular benefits, especially compared to swimming laps.

Conclusion

Swimming laps stands out as the best option for an overweight, middle-aged person at risk for cardiovascular disease due to its vigorous nature and low-impact benefits. Other options, while potentially beneficial, do not provide the same level of intensity or comprehensive cardiovascular engagement necessary for improving heart health.
