What is the target heart rate zone (THRZ) for general cardiovascular training?

The target heart rate zone (THRZ) for general cardiovascular training is most effectively encompassed by the range of 50-85% of an individual's maximum heart rate, which corresponds to the choice that states this range. This zone is critical for improving cardiovascular fitness because it represents the intensity level at which the heart, lungs, and muscles can efficiently work together to enhance aerobic capacity and endurance.

Exercising within this range allows for a sufficient overload while still enabling the body to adapt to the training stresses over time. Additionally, training in this zone promotes fat burning, cardiovascular efficiency, and the overall effectiveness of aerobic workouts. Staying within this range also minimizes the risk of overexertion and injury, especially for those who are new to exercise or have underlying health concerns.

Engaging in exercise outside of this range, such as at excessively high intensities, may not provide the same benefits for general cardiovascular conditioning and can lead to fatigue or injury. Meanwhile, training at the lower end may not sufficiently challenge the cardiovascular system to produce the desired improvements in fitness. Therefore, the recognized target heart rate zone for general cardiovascular training is accurately represented by the 50-85% range of maximum heart rate.
