What is the MET range for moderate-intensity physical activity?

The MET range for moderate-intensity physical activity is accurately identified as 3-6 METs. MET, or Metabolic Equivalent of Task, is a unit that estimates the energy expenditure of physical activities. One MET is defined as the energy cost of sitting quietly, which is about 1 kcal/kg/hour.

Moderate-intensity activities typically require more effort than resting but do not push an individual to their limits. Activities such as brisk walking, cycling at a moderate pace, or dancing can generally fall within this MET range. At 3-6 METs, individuals can usually talk but not sing while engaged in these activities, helping to gauge intensity.

Options that fall outside this range, such as 1.5-3.0 METs, primarily represent light-intensity activities, while 6-9 METs and 9-12 METs correspond to vigorous-intensity activities. Thus, the 3-6 MET range distinctly categorizes the moderate-intensity level, making it the correct answer for this question.
