摘要: Succinate dehydrogenase (SDH) activities and cross-sectional areas (CSAs) of different types fibers in the superficial (EDLs) deep (EDLd) regions extensor digitorum longus soleus (SOL) muscles left ventricular muscle heart (HEART) 10-week-old male rats were determined using quantitative histochemistry a computer-assisted image processing system. The classified as type I, IIA, IIB, or IIC according to their histochemically assessed adenosine triphosphatase activities. mean SDH activity was higher CSA smaller IIA than IIB both EDLs EDLd. SOL that I fibers. Fibers HEART showed highest smallest among all fiber examined. There an inverse correlation between for muscles. These data suggest is type- size-specific, contributes functional properties, i.e., high fatigue resistance.
