Table 4. Metabolic equivalent tasks (METs) can be used to assess functional status in liver transplant candidates.

METS	Estimated functional capacity
>10	Excellent: rope jumping, rowing, running (>7 mph)
7–10	Good: running (6 mph), circuit training
4–6	Moderate: walking up 2 flights of stairs, walking on level ground at 4 mph, cycling for leisure or commuting
<4	Poor: slow ballroom dancing, walking at 2–3 mph, light house work (cleaning, sweeping)

One MET is considered the resting oxygen consumption of a 40-year-old 70 kg man. Adapted from (118).
