Aerobic exercise capacity in patients with juvenile dermatomyositis.

Abstract

Aerobic exercise testing on a treadmill was possible in patients with JDM and revealed an impairment in their maximal aerobic exercise capacity. Exercise time can be used as an indicator of VO2peak, when converted to VO2peak using a regression equation. VO2peak, measured or estimated, has the potential to be a good indicator of muscle function in patients with JDM.
