The acute muscular response to blood flow-restricted exercise with very low relative pressure.
Clin Physiol Funct Imaging. 2018 Mar; 38(2):304-311.CP

Abstract

To investigate the acute responses to blood flow-restricted (BFR) exercise across low, moderate and high relative pressures. Muscle thickness, maximal voluntary contraction (MVC) and electromyography (EMG) amplitude were assessed following exercise with six different BFR pressures: 0%, 10%, 20%, 30%, 50% and 90% of arterial occlusion pressure (AOP). There were differences between each time point within each condition for muscle thickness, which increased postexercise [+0·47 (0·40, 0·54) cm] and then trended towards baseline. For MVC, higher pressures resulted in greater decrements than lower pressures [e.g. 10% AOP: -20·7 (-15·5, -25·8) Nm versus 90% AOP: -24 (-19·1, -28·9) Nm] postexercise. EMG amplitude increased from the first three repetitions to the last three repetitions within each set. When using a common BFR protocol with 30% 1RM, applying BFR does not seem to augment acute responses over that of exercise alone when exercise is taken to failure.
