“…The metabolic properties of muscle fibers also differ among fiber types [12,30,31]. The oxidative enzyme activity is higher in type IIA fibers than in type I fibers of the rat slow skeletal muscle, while the oxidative enzyme activity is higher in type I and type IIA fibers than in type IIB fibers of the rat fast skeletal muscle.…”

“…The fiber type distribution of the soleus muscle was determined from the entire transverse section of the muscle, while that of the plantaris muscle was determined from~500 fibers in the middle region of the transverse section of the muscle. The cross-sectional area of each fiber was measured using a computer-assisted image processing system (Neuroimaging System) on the ATPase-stained (pH 10.4) sections [12,30,31].…”

We investigated whether a relationship exists between the fiber type distribution in skeletal muscles and the insulin resistance of different ages of diabetic rats. The fiber type distributions of the slow soleus and fast plantaris muscles in 5-, 9-, and 21-week-old male Otsuka LongEvans Tokushima Fatty (OLETF) rats as an animal model of spontaneous type 2 diabetes mellitus were examined and compared with those in age-matched nondiabetic Long-Evans Tokushima Otsuka (LETO) rats. In the soleus muscle, a higher percentage of type I fibers was observed in the 9-and 21-week-old OLETF rats compared with the age-matched LETO rats, and there were no type IIA fibers remaining in the soleus muscle of the OLETF rats. In the plantaris muscle, a lower percentage of type IIA fibers and a higher percentage of type IIB fibers were observed in the 9-and 21-week-old OLETF rats compared with the agematched LETO rats. In addition, a lower percentage of type I fibers in the plantaris muscle was observed in the 9-weekold OLETF rats compared with the agematched LETO rats, and there were no type I fibers in the plantaris muscle of the 21-week-old OLETF rats. All 20-weekold OLETF rats showed serum insulin concentrations of more than 20 ng/ml. The present study suggests that insulin resistance and impaired glucose tolerance from altered muscle fiber type are linked to the cause of diabetes.

“…Skeletal muscle fibers generally consist of type 1 (slow twitch, oxidative), type 2A (fast twitch, oxidative, glycolytic) and type 2B (fast twitch, glycolytic) fibers, which can be identified by ATPase staining [4]. These fibers demonstrate physiologic properties unique to each type, and these properties have been shown to be closely related to muscle function [12]. Different types of myosin isoforms, e.g., alpha-cardiac and neonatal isoforms, have also been described in the masseter [5,30,35].…”

“…The sections were incubated for the demonstration of ATPase and SDH [12,13,23,24]. For determination of the alkali preincubation ATPase activity, the following procedures were employed: 1) preincubation for 15 min at room temperature in 75 mM glycine, 50 mM CaCl2, and 75 mM NaCl in distilled water, adjusted to pH 10.4 with NaOH; 2) washing in 5 changes of distilled water; 3) incubation for 45 min at 37°C in 2.8 mM ATP, 50 mM CaCl 2 , and 75 mM NaCl in distilled water, adjusted to pH 9.4 with NaOH; 4) washing in 5 changes of distilled water; 5) immersion for 3 min in 1% CaCl2; 6) washing in 5 changes of distilled water; 7) immersion for 3 min in 2% CoCl2; 8) washing in 5 changes of distilled water; 9) immersion for 1 min in 1% (NH 4 ) 2 S; 10) washing in 5 changes of distilled water; and 11) dehydration in a graded series of ethanol, passing through xylene and then coverslipping.…”

Fiber type distributions, cross-sectional areas (CSAs), and succinate dehydrogenase (SDH) activities of the slow soleus (SOL) muscle and the deep (EDLd) and superficial (EDLs) regions of the fast extensor digitorum longus (EDL) muscle were determined in 10-and 20-week-old male spontaneously hypertensive rats (SHR) and compared with those in agematched normotensive Wistar-Kyoto rats (WKY). There were no differences in the body weight or the SOL and EDL weight between WKY and SHR at 10 weeks of age, while the body weight and the SOL and EDL weight were lower in SHR than in WKY at 20 weeks of age. A higher percentage of type IIA and type IIC fibers and a lower percentage of type I fibers were observed in SOL of SHR at 10 weeks of age. A higher percentage of type IIB fibers and a lower percentage of type IIA fibers were observed in EDLd and EDLs of SHR at 10 weeks of age. In contrast, there were no differences in the fiber type distribution, except a higher percentage of type IIA fibers and a lower percentage of type I fibers in EDLd of SHR, in SOL, EDLd, or EDLs between WKY and SHR at 20 weeks of age. There were no differences in the CSA, except a smaller CSA of type IIC fibers in SOL of SHR, in SOL, EDLd, or EDLs between WKY and SHR at 10 weeks of age. In contrast, a smaller CSA of type I fibers was observed in SOL of SHR at 20 weeks of age. A smaller CSA of all types of fibers in EDLd and of type IIA fibers in EDLs was observed in SHR at 20 weeks of age. There were no differences in the SDH activity of fibers between WKY and SHR, irrespective of the age and fiber type. It is concluded that age-related differences in the fiber type distribution or CSA are observed in the skeletal muscles between SHR and WKY.
