Blood Flow Restriction Resistance Training Intervention on Vascular Function

The purpose of this study is to investigate the effect of blood flow restriction (BFR) resistance training on vascular function. The investigators aim to compare the effects of different BFR devices (wide-rigid cuffs and narrow elastic bands) on vascular function. The investigators hypothesize that BFR resistance training with wide-rigid cuffs might have a minor negative effect (short-term and reversible) on vascular function, while BFR resistance training with narrow-elastic bands may improve vascular function. Both training methods are equally effective in increasing muscle strength.
