Effects of exercise on substrate availability and capacity for oxidation. Histochemical analyses were performed on skeletal muscle biopsy samples obtained as described in METHODS; n = 25. A: intramyocellular lipid (IMCL) content was measured by Oil Red O staining. B: oxidative capacity was measured by succinate dehydrogenase (SDH) staining. C: glycogen content was measured by a Schiff’s reagent protocol. D: capillary density. E: percentage of type I slow oxidative fibers. Statistical significance is indicated. Data are means ± SE. AU, arbitrary units.
