In the context of exercise intensity, what MET level indicates vigorous activity?

Vigorous activity is defined by its intensity, which can be measured in metabolic equivalents (METs). METs quantify the energy cost of physical activities as a multiple of basal metabolic rate (BMR).

An activity that is classified as vigorous typically has a MET level greater than 6. This indicates a significantly increased energy expenditure, reflecting higher levels of effort that require more oxygen consumption and higher heart rates compared to lower intensity activities. For example, activities such as running, high-intensity interval training, or competitive sports often fall into this category, promoting improvements in cardiovascular fitness, muscular strength, and weight management.

Levels below 6 METs generally represent moderate or light-intensity activities, which may not evoke the same level of cardiovascular strain and energy expenditure as those soaring above this threshold. Hence, recognizing the MET classification helps in designing effective exercise interventions, tailoring them based on a person's fitness level and weight management goals.
