Abstract
To date, there have been few intervention studies concerning the association of metabolic syndrome with beta 3-adrenergic receptor (ADRB3) Trp64Arg polymorphism, although ADRB3 Trp64Arg polymorphism has been reported to be associated with weight gain and insulin resistance by several intervention programs. We examined the influence of ADRB3 Trp64Arg polymorphism on the improvement of metabolic syndrome by an exercise-based intervention program. Thirty-six male employees who satisfied the metabolic syndrome criteria participated in a three-month exercise-based intervention program (average age, 49 ± 6 years old). The improvement rate of metabolic syndrome after the intervention was compared between subjects with and without ADRB3 Trp64Arg polymorphism. The Mantel-Haenszel test was employed to adjust the age, diet, and exercise in analysis of the influence of ADRB3 Trp64Arg polymorphism on metabolic syndrome. The Trp64Arg genotype of the β3-adrenoceptor gene was examined in peripheral blood leukocyte DNA by TaqMan PCR assay. The distribution of polymorphism was 23 (Trp/Trp), 13 (Trp/Arg), and 0 (Arg/Arg). The metabolic syndrome improvement rates after intervention were 21.7% (Trp/Trp) and 53.8% (Trp/Arg) (p = 0.050). After adjust...Continue Reading
