The influence of adiponectin G276T gene polymorphism on changes in total and high molecular weight adiponectin levels by exercise training

摘要

Adiponectin is an adipocyte-secreted hormone and regulates the metabolism of lipid and glucose. We examined the influence of adiponectin G276T gene polymorphism on changes in total or high molecular weight adiponectin levels by exercise training. A randomized parallel-design study (n = 53; 40 women and 13 men; age range, 32 - 65 years) was conducted. Participants were randomly assigned to the exercise (n = 26) or control (n = 27) group and received exercise training for 70 min 2 times per week for 12 weeks and exercise advice at the baseline, respectively. Blood sample were obtained before and after the intervention. The primary outcomes were changes in total adiponectin and high molecular weight adiponectin levels. At the baseline, the participants with and without 276G allele did not differ with the total and high molecular weight adiponectin levels in the entire study population. No significant difference in the change in the total and high molecular weight adiponectin levels between the subjects with the G276G genotype and 276T allele carriers were found. This study provides evidence that the G276T polymorphism of the adiponectin gene is not associated with the magnitude of the effect of twice-weekly exercise training on the total and high molecular weight adiponectin levels.
