What percentage range of maximum heart rate defines the target zone for cardiovascular health?

The target zone for cardiovascular health is generally defined as a percentage of an individual's maximum heart rate that ensures effective aerobic exercise. When exercising within the range of 60-85% of maximum heart rate, individuals are engaging in moderate to vigorous intensity workouts that can significantly improve cardiovascular endurance and overall heart health. This range is optimal for building stamina, enhancing the body's ability to deliver oxygen to muscles, and improving overall health metrics.

Working at this intensity helps to increase the heart's efficiency and capacity, lowers resting heart rate over time, and can lead to various health benefits, such as reduced risk of heart disease, improved lung capacity, and better physical performance. It is important to note that while lower percentages may contribute to light physical activity, they might not sufficiently challenge the cardiovascular system to stimulate significant improvements in health. Conversely, exercising at percentages that are too high might lead to decreased performance and increased risk of injury.

Thus, the 60-85% range is recognized as the most effective and safe for most individuals aiming to enhance cardiovascular fitness, making it the correct answer for this question.
