(A–F) Metabolic pathways whose metabolites change with exercise in patients with mitochondrial myopathy or McArdle disease. Metabolite levels during exercise shown for those in pathways found to have significantly different excursions in the post/rest comparison. The measurements are in logged arbitrary units (A.U.). Metabolites with significantly different excursions from rest to peak are indicated by an asterisk (*); those that significantly differ from rest to post are indicated by a double dagger (^‡).
