Which MET range defines Moderate intensity?

• A. Moderate 3.0-5.9 MET
• B. Light 1.8-2.9 MET
• C. Vigorous >6.0 MET
• D. 0-1.0 MET

Answer: (A)

Moderate intensity is defined by energy cost about 3.0 to 5.9 METs, meaning the activity uses roughly three to six times the energy you use at rest. One MET is the energy your body expends at rest, so activities in the 3.0–5.9 MET range are clearly more demanding than resting but not as demanding as vigorous efforts. That’s why the option listing 3.0–5.9 METs best fits moderate intensity.

To contrast, very light activities fall around 1.8–2.9 MET, which are easy enough that your body isn’t taxed much; resting activities are 0–1 MET; and vigorous activities are 6.0 METs or more, which push your energy use well beyond moderate levels. When engaging in moderate-intensity activity, you should notice your breathing quicken and your heart rate rise a bit, but you’re still able to carry on a conversation. Examples include brisk walking, cycling on flat ground at a comfortable pace, or dancing at a steady tempo.
