Abstract
Background
The purpose of study was to examine the effects of regulatory resistance exercise for 12 weeks on lipolysis pathway in pre- and post- menopausal women with obesity.
Methods
Twenty-three pre- and post- menopausal women with body fat percentages of 30% or more divided into pre- menopausal group (n = 9) and post- menopausal group (n = 14). All subjects participated in resistance exercise training for 12 weeks. All participant’s anthropometric measurements and physical fitness tests were performed. Protein analyses were performed with subcutaneous fatty tissue extracted, and the samples were analyzed of relevant protein expression changes by using Western blotting. All serum samples were submitted for enzyme-linked immunosorbent assay measurements of adipocyte factors.
Results
After 12 weeks between pre- menopausal and post- menopausal groups ATGL, MGL and PLIN protein expression were significantly lower in the post- menopausal group than in the pre- menopausal group. HSL protein expression were significantly higher in the post- menopausal group than in the pre- menopausal group. In addition, leptin concentration was significantly decreased, and adiponectin concentration was significantly increased after resistance exercise in the post- menopausal group more than pre- menopausal group.
Conclusions
In this study indicates that regular resistance exercise to change of leptin and adiponectin might be release of overall decreased ATGL, HSL, MGL and PLIN expression in subcutaneous fatty tissue, and driving reduction of % fat in the obese post- menopausal group more than obese pre- menopausal group.
