Exercise and aerobic capacity are increased in myositis patients after 12 weeks endurance training. A. Individual data of the concentration of lactate in muscle dialysate after cycling vs. cycling time (at the same absolute work load for each subject) obtained in nine patients before (open circles) and after (filled circles) endurance training. Mean data (± SD) before (open triangle) and after (filled triangle) training are also shown. B. Same as in A but for six patients in the control group (no training). Mean data (± SD) of VO2 max (C) and the corresponding power (D) before (white bars) and after (black bars) the 12-week intervention period in the exercise group (EG, n = 7) and the control group (CG, n = 5). E and F show mean data (± SD) of the change in VO2 max and power after vs. before the intervention period in individual subjects.
