Abstract
We hypothesized that strict inactivity (bed-rest) would lead to regional differences in fat deposition. Twenty-four male subjects underwent 60d bed-rest and remained inactive (n=9), performed resistance exercise plus whole-body vibration (RVE; n=7) or resistance exercise only (RE; n=8). Fat mass was assessed via dual X-ray absorptiometry. In the inactive subjects, fat deposition differed between body regions (P=0.0005) with android region visceral adipose tissue increasing the most (+29% at end bed-rest), followed by remainder of the trunk (from chin to the iliac crest; +10%) and the arms and legs (both +7%). Insulin sensitivity reduced in the inactive subjects at the end of bed-rest (P=0.036). RE did not have a significant impact on regional fat mass changes (P>/=0.055). In RVE, increases in visceral adipose tissue (-14% P=0.028 versus inactive subjects) and in the arms (arms -8%, P=0.011 versus inactive) were not seen. We conclude that inactivity leads to a preferential increase in visceral adipose tissue.International Journal of Obesity accepted article preview online, 13 February 2014; doi:10.1038/ijo.2014.26.Keywords: Reduction of Fat / Adipose tissue, visceral adipose tissue
