Diffusive O2 conductance (do2) in the leg and the arm. do2 is defined as the slope of the regression lines extended to the origin (220). Each data point is the calculated mean DO2 from knee extension (9, 118, 20, 157, 168, 157), skiing (23), cycling (22, 25, 93, 160), arm cranking (19, 77, 207, 218), and arm skiing (22). The data confirm across exercise modalities a twofold higher muscle do2 in the legs compared with the arms.
