What term refers to a predetermined pulse rate to be achieved during exercise, expressed as a percentage of MHR?

The term that refers to a predetermined pulse rate to be achieved during exercise, expressed as a percentage of Maximum Heart Rate (MHR), is known as the target heart rate. This concept is essential in exercise and fitness as it helps individuals gauge the intensity of their workouts. By maintaining exercise intensity within the target heart rate zone, one can optimize cardiovascular benefits, enhance fat burning, and improve overall fitness levels.

Establishing a target heart rate is particularly useful for those training for specific fitness goals, as it provides a clear benchmark for effort during physical activity. It ensures that individuals are working hard enough to challenge their cardiovascular systems while not overexerting themselves, which can lead to fatigue or injury.

Other terms, such as maximum heart rate, represent the highest heart rate an individual can achieve during intense exercise and serve as the basis for calculating the target heart rate but are not explicitly the same. Resting heart rate indicates how quickly the heart beats in a resting state and does not relate directly to exercise intensity. Optimal heart rate is not a standard term used in the context of exercise; rather, it’s a vague descriptor that does not provide the specificity needed for effective training.
