Abstract

 Body weight (BW) and blood pressure (BP) have a close relationship, which has been accounted for by hormonal changes.

No previous study has evaluated the effect of wearing an external weight vest on BP to determine whether there is a simple mechanism between BW and BP. Seventeen healthy volunteers underwent weight reduction (WR) through caloric restriction.

Before and after WR, BW, body fat percentage and BP at rest and during exercise were measured.

Before and after WR, exercise testing was performed twice with the random allocation of a weight vest (10 kg) during one of the tests.

Linear regression was used to detect independent associations between BP and the weight vest, BW and body fat percentage. BW decreased from 89.4±15.4 kg to 79.1±14.0 kg following WR (P<0.001).

 WR led to significant decreases in BP at rest (from 130.0/85.9 mm Hg to 112.5/77.8 mm Hg, P
