Exercise Training Prevents Decrease in Luminal Capillary Diameter of Skeletal Muscles in Rats with Type 2 Diabetes

Figure 4

(a)–(c) Succinate dehydrogenase (SDH) staining of transverse sections of the soleus muscle from the control (Con, (a)), diabetes (DB, (b)), and diabetes with exercise (DBEx, (c)) groups. Staining intensity is directly related to SDH activity; darker muscle fibres indicate higher activity. (d) SDH activity in the Con, DB, and DBEx groups. au: arbitrary unit. All values indicate fold changes relative to the Con group. Bars represent standard error. * and † indicate significant differences in the Con and DB groups, respectively, at 𝑃<0.05. Bar = 50 μm.
