Effects of NPV-exercise training vs. control on 6-minute walk distance. A. Individual changes of 6MWD in both groups before and after the 12-week course (Control, n = 18; NPV-exercise, n = 18). B. Comparisons of delta-6MWD (Δ6MWD; changes from the base line after 12 weeks; mean ± SD) between both groups (Control, n = 18; NPV-exercise, n = 18). C. Time course of 6MWD in the NPV-exercise group (n = 14) during the 12 months.
