What is the anaerobic exercise intensity range for heart rate percentage?

The anaerobic exercise intensity range for heart rate percentage generally falls within the range of 80%-85%, making this the correct choice. This range reflects a high level of exertion where the body primarily relies on anaerobic metabolism for energy, producing energy without the use of oxygen.

During anaerobic exercise, such as sprinting or high-intensity interval training, the heart rate is elevated significantly. This intensity level is important for developing strength, power, and muscle mass, as it stimulates greater hormonal responses and muscle fiber recruitment.

Intervals of activity within this range often push the body to its limits, resulting in improved performance and increased lactate threshold, allowing individuals to sustain higher levels of activity over time. On the other hand, lower heart rate percentages, such as those below this range, are typically associated with aerobic exercise, which primarily uses oxygen for energy and is more suited to endurance activities rather than high-intensity efforts.
