We determined acute endurance exercise on mTOR signaling responses in aging skeletal muscle(soleus; SOL, extensor digitorium longus; EDL). Total 32 Sprague-Dawley rats were divided into two groups by age; young group(YG; 20wk; n=16) or old group(OG; 72wk; n=16). Each experimental group was further allocated two subgroups; Exercise(EX; n=8), Control(CON; n=8) group. All animals in exercise group performed one bout of 3hr endurance swimming exercise (30min×6bouts). The phosphorylation of mammalian target of rapamycin(mTOR) and p70 ribosomal S6 kinase(p70S6K) were significantly increased in 20wk(YG) soleus (p<.05). However, the phosphorylation of mTOR and eukaryotic initiation of factor 4E binding protein 1(4EBP1) were significantly decreased in 72wk(OG) muscles(p<.05) after endurance acute swimming exercise. The phosphorylation state of AMPK was significantly increased in 20wk(YG) muscles(p<.05) and 72wk soleus(p<.01) after exercise.
The results suggest that a bout endurance exercise was increased AMPK activity but inhibited mTOR and 4E-BP1 phosphorylation in aging slow-twitch muscle.
