Figure 2. Effects of a single bout of moderate exercise on expression of GLUT4 mRNA and GAPDH mRNA in soleus and gastrocnemius muscle. Muscle samples were collected at 5 and 20 minutes after the onset of exercise, at the end of exercise (60min), and 3 h post-exercise. GLUT4 mRNA band intensity was determined using ATTO Densitograph software library.
