TL;DR
Scanning electron microscopy was used on specially prepared specimens to determine the distinctive features of mitochondria and sarcoplasmic reticulum in each fiber type.
Abstract
Mitochondrial shape and configuration were distinctive for each human skeletal muscle fiber type, but the SR was similar in all muscles examined.

A revised Osmium‐DMSO‐Osmium method is reported, in which an aldehyde mixture is used as the initial fixative instead of osmium tetroxide, and better preservation of fine structures is achieved than by the original method.

Most of the mammalian striated muscle fibers fell into three types following a histochemical demonstration of oxidative enzyme reaction: Small red muscle fibers showed higher activities of oxidative enzymes, while large white fibers lower activities and the third type of fibers, "medium fiber" which were intermediate in size showed activities between red and white muscle fibers.

Blocks of the kidney and other organs of the guinea pig fixed with glutaraldehyde and treated with tannic acid and osmium tetroxide could be observed in the scanning electron microscope without any coating, avoiding the metal coating which obscures the details of the specimen surface.

There is a good parallelism between succinic dehydrogenase activity and stainability to Sudan black B among the three types of muscle fibers and there is no correlation between the size and the enzymatic activity and sudanophilicity differing from the latter.

The fine structure of fiber types in the human vastus lateralis muscle is described and the two types seem to differ only in the number and size of mitochondria and not in the amount of sarcoplasmic reticulum or the structure of myofibrils.

A histochemical and electron microscopic study of the cytological features of the fiber types in normal human intercostal muscle is presented and attention has been further paid to the sarcoplasmic reticulum, lipid droplets and glycogen particles.

It was found that complete tissue fixation occurred only after the chemical crosslinking of proteins with aldehyde which was a gradual process, and MWI is excellent for micro- and electron autoradiography and also for X-ray microanalysis.

This system of fiber typing based on relative Z-line and M-line widths was applied to several abnormal muscle biopsies each of which showed a deficiency in at least 1 of the major histochemical fiber types.

The results show that no single feature can be used to distinguish fibre types reliably and that if 2 factors are measured and certain assumptions are made, it is possible to classify about 50% of the fibres examined.
