What METs define Vigorous Intensity?

• A. ≥6 METs
• B. 3-6 METs
• C. <3 METs
• D. 1.6-2.9 METs

Answer: (A)

Metabolic equivalents (METs) measure exercise intensity by how much energy an activity requires relative to rest. Vigorous intensity is defined as activities that burn energy at six METs or more. This threshold reflects a high level of cardiovascular and respiratory demand, enough to noticeably raise heart rate and breathing and often limit conversation. For context, light intensity is typically below 3 METs, moderate intensity falls around 3 to 5.9 METs, and very light to minimal effort is about 1.6 to 2.9 METs. Examples of vigorous activities include fast running, vigorous cycling, and competitive sports, which meet or exceed six METs.
