How many METs are associated with climbing 2 flights of stairs?

Climbing two flights of stairs typically involves an energy expenditure that is well-captured by the metabolic equivalent of task (MET) scale. The MET scale is a standard measure that is used to represent the energy cost of physical activities, where one MET is defined as the energy expended while sitting quietly (approximately 3.5 ml of oxygen per kg of body weight per minute).

For moderate activities like climbing stairs, the MET value tends to range higher because it requires more cardiovascular effort and muscle engagement. Research and exercise physiology suggest that climbing stairs has a MET value that can vary based on intensity; however, a general estimate for climbing one flight of stairs is about 3 to 5 METs.

Since climbing two flights of stairs typically increases the physical demand, it is reasonable to attribute a MET value of approximately 5 to 6, depending on the speed and fitness level of the individual. The choice of 5 METs aligns with the physical rigor associated with this activity, as it highlights the increase in energy expenditure when compared to more sedentary activities, confirming that this option effectively encapsulates the exertion associated with climbing two flights of stairs. Therefore, 5 METs is the accurate representation of this activity level on the MET scale
