BLOOD FLOW RESTRICTION TRAINING

Blood flow restriction training is one of the newest training tools to be used in the rehab and performance worlds. There is a lot of research supporting the use of this modality for strength and hypertrophy gains.

Research on blood flow restriction training shows that loads as low as 20-30% of 1rm can create the same hypertrophy stimulus. This allows blood flow to a region, while restricting venous return which results in increased type 2 fibre recruitment (Greater potential for strength, speed and hypertrophy (size) in muscles). An increased local Growth hormone and IGF-1 levels by 200-300% which reduce muscle breakdown and increased collagen protection. We also achieve enhanced stimulation of muscle protein synthesis by 45-55%.
These things allow for the ability to train at a low intensity but achieve as good if not better growth in your muscles as high intensity, patients with injuries and/or contraindications to a high load, to train and achieve outcomes and the ability to achieve strength and size in a much shorter period with less intensity/load.

A Study by Takarada, 2000 showed the average change in elbow flexors cross sectional area between different training intensities. These changes were low intensity 2%, low intensity with BFR 20% and high intensity 12%. As such much larger gains in size were achieved without an increase in the load.
There are many possible uses that extend past the athletic population such as rehab post total knee reconstruction, ACL reconstructions, tennis elbow and Patella/Achilles tendinopathies to name a few.
