The authors measured serum adiponectin by using the ELISA method, measured AdipoR1, AdipoR2 and PPARγ and AMPKα protein expression by using the RT-PCR method, and revealed the following findings: 1) the levels of serum adiponectin of the rats in the model groups was lower than those of the rats in the normal control group, while the rats in the resveratrol exercising group in the model groups had the highest level of serum adiponectin; 2) the levels of protein expression of adi-ponectin receptors 1 and 2 of the rats in the resveratrol exercising group were all higher than those of the rats in other model groups; 3) the rats in the normal control group had the highest level of PPARγmRNA expression, while the rats in the resveratrol exercising group had the highest level of AMPKαmRNA expression. The said findings in-dicated the followings: In this experiment, the exercising and resveratrol combined intervention boosted the levels of serum adiponectin and receptors, thus lowering relevant indexes such as TG and GLU; adiponectin receptors ac-tivated downstream signaling pathway proteins AMPKαmRNA and PPARγmRNA, and increased their expression, thus improving the disordering of visceral fat cells of the rats, reducing fat synthesis, boosting the removal of serum TG and reducing fat tissues and fat accumulation to a certain extent, playing a certain role in improving rat obesity.
