Prevention: Exercise

European Heart Journal ( 2019 ) 40 ( Supplement ), 1460

Objectives: Visceral adipose tissue (VAT) plays pivotal roles for an increased risk of cardiometabolic disease through triggering inflammatory process. This prospective study aimed to evaluate whether the exercise training could reduce inflammatory activity of VAT assessed by 18F-fluorodeoxyglucoase (FDG) positron emission tomography-computerized tomography (PET/CT).

Methods: Twenty-three overweight women who participated in exercise training program were included. Exercise training program was composed of aerobic exercise (45 min/session, 300 Kcal/day) and muscle strength training (20 min/session, 100 Kcal/day) 5 times per week for 3 months. They underwent F-18 FDG PET/CT before starting exercise program (baseline) and after completion of 3 months exercise program. Anthropometric data, clinical laboratory data, VAT area, and maximum standardized uptake value (SUVmax) of VAT were compared between baseline and after completion of the total exercise program.

Results: Baseline VAT SUVmax showed significant correlation with body weight, body mass index (BMI), waist circumference, and hip circumference. VAT SUVmax was significantly reduced by exercise training program. Exercise training program also reduced body weight, BMI, waist circumference, hip circumference, VAT area, subcutaneous adipose tissue area and blood pressure. The change of VAT SUVmax was significantly higher than the change of VAT area.

Conclusions: Exercise training could reduce the inflammatory activity of VAT assessed by F-18 FDG PET/CT. Thus, exercise would be a promising non-pharmacological strategy to reduce inflammatory activity of VAT. Furthermore, F-18 FDG PET/CT could be useful to evaluate the effect of therapeutic intervention targeted to inflammatory VAT activity.
