What percentage of maximum heart rate should students aim for during exercise for health-related fitness?

The correct percentage of maximum heart rate that students should aim for during exercise for health-related fitness is 60-85%. This zone is often referred to as the "aerobic zone," where exercise is sufficiently intense to build cardiovascular endurance without being overly strenuous. Engaging in activities within this range allows individuals to improve their heart and lung function, increase their overall fitness levels, and enhance endurance capabilities.

Exercising at 60-85% of maximum heart rate is effective because it promotes improvements in cardiovascular fitness, supports weight management, and can contribute to overall health benefits. This intensity level is suitable for individuals who are already somewhat active, allowing them to maximize health benefits while still being sustainable for longer durations.

It's important to note that lower ranges, such as 40-60%, may not provide sufficient intensity for improving cardiovascular fitness, and the higher ranges of 85-95% may be too intense, particularly for beginners or those unaccustomed to intense physical activity.
