Also known as Occlusion Training or Kaatsu Training was originally conceived and developed in Japan in the late 1960’s by Yoshiaki Sato and termed KAATSU training. It most commonly involves resistance training with low loads of around 20 – 30% of 1 Rep max (1RM), using wraps, cuffs or bandages applied around the top part of trained limb (usually with a perceived tightness of 7 out of 10).
Research has demonstrated that using low-load resistance training with BFR can produce significant strength and hypertrophy gains. BFR training has been found to yield hypertrophy responses comparable to that observed with heavy-load resistance training. Studies have also shown using walk-training along with BFR to the legs can increase muscle strength and size.
