Objective: To study the effect of aerobic exercise training on insulin resistance, lipid metabolism and inflammatory response in patients with Alzheimer’s disease (AD). Methods: A total of 84 patients who were diagnosed with Alzheimer’s disease in the Mental Health Center in Zigong City between June 2014 and December 2016 were selected and randomly divided into aerobic exercise group and normal control group who received aerobic exercise intervention combined with conventional drug therapy and conventional drug therapy respectively. The insulin resistance indexes, blood lipid metabolism indexes and inflammatory response indicators were detected before intervention as well as 3 months and 6 months after intervention. Results: 3 months and 6 months after intervention, the HOMA-IR levels as well as serum TC, LDL-C, ApoB, TNF-α, MCP-1, MIA-1α and HMGB1 contents of aerobic exercise group were significantly lower than those before intervention while HOMA-β, ISIcomp and MBCI levels as well as serum HDL-C and ApoAI contents were significantly higher than those before intervention; the HOMA-IR, HOMA-β, ISIcomp and MBCI levels as well as serum TC, LDL-C, HDL-C, ApoAI, ApoB, TNF-α, MCP-1, MIA-1α and HMGB1 contents of normal control group were not statistically different from those before intervention. Conclusion: Aerobic exercise training can improve insulin resistance and blood lipid metabolism, and inhibit inflammatory response in patients with AD.
