title: Energy metabolism of fibre types within fascicles of human muscles.
abstract: In human latissimus dorsi muscle a preponderance of type 2b fibres in the first fascicle layer and of type 1 fibres in the second layer was found. NADH-dehydrogenase (NADH) and alpha-glycerophosphate dehydrogenase (GPDH) which were measured histophotometrically in type 1, 2a, and 2b fibres showed either extreme or only partial overlapping regarding the activity of metabolic enzymes. In different fascicle layers the average activity of both enzymes did not differ significantly among the fibres of the same type, neither did the NADH and GPDH activity of type 2a and 2b.
