High Blood Flow Restriction Pressure is Necessary to Induce Vascular Adaptations with Very Low-Load Training

Vascular conductance is increased to a similar extent following low load (30% of one repetition maximum (1RM)) resistance training with and without blood flow restriction (BFR). It is unclear, however, if very low force (<30% 1RM) contractions require BFR to produce this effect. It is also relatively unknown if or how the venous system changes following chronic BFR as this type of training causes blood to dam up in the veins during BFR. PURPOSE:...
