METHODS Muscle biopsies were obtained from the left vastus lateralis (Case I), right vastus
lateralis (Case 3), and left biceps (Cases 2 and 4). Specimens for histochemistry were frozen
immediately in isopentane cooled in liquid nitrogen and subsequently sectioned at 10 p in a
cryostat. A battery of 17 histochemical reactions was used as detailed elsewhere. 3 Fiber
typing was done on sections stained for myofibrillar adenosine triphosphatase (ATPase) at a
pH of 9.4899 and confirmed with other reactions, especially the one for EDTA-low pH …
