Spot reduction, intensity, and metabolic versus circulatory demands

It remains unclear whether the effects observed in the current study are predominantly related to metabolic or circulatory mechanisms during training or recovery after exercise. The rate of peripheral adipocyte lipolysis, from subcutaneous or visceral adipose tissue, is documented to be highest during exercise with low intensity and decreases as intensity progresses (Romijn et al., In theory, if spot reduction was mainly caused by replenishment of glycogen storages through gluconeogenetic processes during recovery (Frayn, In the CG, total lean mass decreased by 1.6 kg (2%) after 10 weeks, more than in the AG where no change was observed. As basal metabolic rate is closely related to changes in fat‐free mass, a 1.6 kg decrease in lean tissue may result in reduced energy expenditure by ~25–35 kCal per day, and in turn less fat oxidation (McArdle et al., The intensity applied in the abdominal endurance exercises for the current study, chosen specifically to emulate aerobic interval training, is shown to improve oxygen transport and utilization (Helgerud et al.,
