DISCUSSION
overweight
It has been well accepted that exercise‐induced lipolysis occurs predominantly through whole‐body fat release, rather than from local adipose tissue storages adjacent to the working muscles. However, to date no study has investigated the concept of spot reduction/lipolysis by comparing abdominal aerobic endurance training (AG) with whole‐body treadmill endurance training (CG) closely matched for total energy expenditure in a randomized controlled trial. The main finding from the current study was that after 10 weeks and 40 training sessions, fat mass located in the trunk decreased more (697 g, 3%) in the AG than in the CG, while total fat mass and body weight decreased similarly in both groups. These findings demonstrate the efficacy of the protocol to investigate differences in adipose tissue utilization, and that spot reduction exist in the trunk region in overweight adult males.
