METhOds: Fourteen older (67.9 ± 1.2 yr) obese adults (BMI: 34.2 ± 1.1kg/m2) with
metabolic syndrome underwent 12-weeks of supervised exercise training (60 minutes/d
for 5 d/week at ~85% HRmax). Peripheral insulin sensitivity was determined by
the euglycemic-hyperinsulinic clamp (40 mU·m2·min-1), hepatic insulin action was
estimated by HOMA-IR, and 2-hr glucose levels were determined after a 75 gram oral
glucose tolerance test. Visceral fat was determined by computerized tomography. Basal
fat oxidation and aerobic fitness was measured by indirect calorimetry. Plasma DPP-4
was analyzed using an enzyme-linked immunosorbent assay.
rEsuLTs: Exercise decreased body weight and visceral fat and increased aerobic
fitness (p
