Duke activity status index (DASI) = SUM (values for all 12 questions).
The most  widely  recognized  measure  of  cardiorespiratory  ftness  is  maximal oxygen  consumption  (VO2peak)  measured  in  mL/kg/min. The Index  score correlates directly with VO2peak and therefore is an indirect measure of maximal METS.

Estimated Peak Oxygen Uptake (VO2peak) in mL/min = (0.43 × [DASI]) + 9.6.

VO2peak mL/kg/min × 0.286 (mL/kg/min)−1 = METS.
