Figure 7. Chronic exercise increases AMPKα1 and AMPKα2 activities in rat adipocytes.

(A) Exercise training for 6 weeks efficiently reduced fat mass without altering body mass. (B and C) AMPKα1 (B) and AMPKα2 (C) activities in epididymal fat from rats trained for 6 weeks and allowed to rest for 36 h before study. Both AMPKα1 and AMPKα2 activities were increased in trained rats. (D) AMPK Thr¹⁷² phosphorylation was increased in trained rats. Results are means±S.E.M.; n=6 per group. *P<0.05, **P<0.01 and ***P<0.001 compared with the control. A.U., arbitrary units.
