According to ACSM, what is the classification of heart rate at low intensity exercise?

The classification of heart rate at low intensity exercise, according to the American College of Sports Medicine (ACSM), is defined as 64% and below of an individual's maximum heart rate. This range indicates that during low intensity exercise, the heart rate remains at a level that is comfortable and manageable, allowing individuals to engage in physical activity without excessive strain. This classification supports guidelines for safe exercise prescription, particularly for populations that may require modified physical activity recommendations, such as those with chronic diseases, the elderly, or deconditioned individuals.

In contrast, the other ranges represent higher levels of heart intensity: 65-75% and 76-90% are categorized as moderate to vigorous intensity exercise, which is more taxing on the cardiovascular system and may not be suitable for everyone, particularly those just beginning an exercise program or with certain health considerations. Understanding these distinctions is crucial for effectively designing exercise routines that meet individual health and fitness needs.
