Which category of METs is considered vigorous activity?

Vigorous activity is typically categorized within the range of 6.0 METs and higher. The Metabolic Equivalent of Task (MET) is a measure of energy expenditure that quantifies the intensity of physical activities. At 6.0 METs, activities require considerably more effort than those classified as moderate and align with what is commonly understood as vigorous exercise.

In the context of MET values, activities that fall into the lower ranges, such as those below 6.0 METs, are generally associated with moderate effort. For example, levels between 3.0 to 5.9 METs denote activities that can elevate heart rate and breathing but are manageable for most individuals. Therefore, identifying vigorous activities involves focusing on those that require a high level of exertion, which begins at 6.0 METs and continues to increase.

Thus, the correct classification for vigorous activities involves understanding that they start at 6.0 METs, making that option the most accurate representation of what constitutes vigorous intensity in physical activity.
