Blood flow restriction training has shown to increase growth hormone which aids in muscle recovery and facilitates the muscle growth and strengthening process. High intensity training, which blood flow restriction training mimics, has been shown to reduce a protein called myostatin which controls and inhibits cell growth in muscle tissue.
Does blood flow restriction therapy improve quadriceps strength after ACL reconstruction?
Background: Low-load blood flow restriction (BFR) training has attracted attention as a potentially effective method of perioperative clinical rehabilitation for patients undergoing orthopaedic procedures. Purpose: To (1) compare the effectiveness of low-load BFR training in conjunction with a standard rehabilitation protocol, pre- and postoperatively, and non-BFR interventions in …
Does BFR therapy improve outcomes after ACL reconstruction surgery?
May 05, 2020 · The purpose of this study is to examine the effect of utilizing blood flow restriction (BFR) therapy both before and after anterior cruciate ligament reconstruction (ACLR) following a tear. BFR has been proposed to work by restricting arterial inflow leading to an oxygen depleted environment and the ability to induce muscle adaption at lower maximum repetition via …
What is the role of physical therapy in the treatment of ACL?
We evaluated the effectiveness of a home-based blood flow restriction (BFR) exercise program to increase quadriceps size and strength several years after ACLR. Nine adults with ACLR (5±2 yrs post-surgery, ≤90% symmetry in quadriceps size and strength) and nine uninjured controls volunteered. ACLR participants exercised at home for 25 min, 5×/wk for 4 wks (single-leg knee …
Does blood flow restriction therapy work for a meniscal tear?
Nov 29, 2018 · The main objective is to determine the impact of Blood Flow Restriction (BFR) therapy, in comparison to a standard rehabilitation protocol, on preventing atrophy, improving quadriceps strength and improving functional outcomes of patients recovering from ACL reconstruction. The investigators hypothesize that patients undergoing BFR therapy after ACL …
Does blood flow restriction training work?
There's evidence that BFR training can indeed boost athletic training, and may even help patients with chronic pain or other conditions build muscle more easily, as long as it's performed correctly.Jul 29, 2021
What are the benefits of blood flow restriction training?
Blood flow restriction (BFR) training has been reported to have significant benefits on local skeletal muscle including increasing local muscle mass, strength, and endurance while exercising with lower resistance. As a result, patients unable to perform traditional resistance training may benefit from this technique.Aug 2, 2021
How does blood flow restriction therapy work?
The goal of Blood Flow Restriction Therapy enables patients to make greater strength gains while lifting lighter loads, thereby reducing the overall stress placed on the limb. BFRT works by decreasing blood flow to working muscles with the aim of promoting hypertrophy, and preventing disuse atrophy of muscles.
When do you start BFR after ACL surgery?
Standard post-operative rehabilitation regimen (REHAB) beginning 1-week after ACL reconstruction with quadriceps tendon autograft. BFR therapy beginning 1-week after ACL reconstruction with quadriceps tendon autograft.Aug 20, 2020
Does blood flow help muscle growth?
Increased blood flow also helps improve muscular efficiency of ATP production in the mitochondria (reducing the oxygen cost of exercise). The removal of ammonia and other metabolites allows athletes to recover more quickly and may result in better growth stimulus and adaptive growth response to micro-tears.Apr 17, 2019
Who can benefit from blood flow restriction therapy?
Who can use it? Blood flow restriction training can be helpful for individuals recovering from an injury or surgery (often to the lower extremities) who are unable to lift heavier weights or exercise at a higher intensity. It's also beneficial for healthy individuals seeking additional strength gains.
When is blood flow restriction therapy used?
Blood flow restriction therapy is most often used to help patients recover from sports injuries, joint pain or surgery. However, it has other uses, too. Blood flow restriction training can be used for general strengthening, especially in certain populations such as the elderly.
How does restricted blood flow affect muscles?
Blood flow restriction reduces arterial blood flow to working muscles while also occluding venous return. In BFR conditions, active muscles encounter a ischemia state which imposes a greater metabolic stress on working muscles (Tanimoto et al., 2005).Jun 26, 2019
How do you increase blood flow to ACL?

How do you do blood flow restriction training?
Blood flow restriction training uses higher metabolically demanding sets & reps with a much shorter rest period between (typically 30-45 seconds). Aim for 15-30 repetitions for 4 sets with only 30 seconds rest between each set. Concentrate as you squeeze out each rep and feel the movements working the muscles.Sep 28, 2018
What is blood occlusion?
An occlusion is a complete or partial blockage of a blood vessel. While occlusions can happen in both veins and arteries, the more serious ones occur in the arteries. An occlusion can reduce or even stop the flow of oxygen-rich blood to downstream vital tissues like the heart, brain, or extremities.
What is BFR therapy?
The main objective is to determine the impact of Blood Flow Restriction (BFR) therapy, in comparison to a standard rehabilitation protocol, on the functional outcomes of patients recovering from ACL reconstruction. The investigators hypothesize that patients undergoing BFR therapy after ACL reconstruction surgery will have better functional outcomes than those undergoing normal rehabilitation without BFR therapy.
How long does BFR last?
BFR exercises will be initiated two weeks post-op, and continued for 16 weeks. Device: Blood Flow Restriction Therapy. A wide pressure cuff will be applied to the upper thigh prior to starting strengthening exercises. The cuff is inflated to 80% of resting systolic blood pressure.
How long does a cuff stay inflated?
The cuff remains inflated for the entirety of the exercise (4 sets of a specific movement). Once the exercises are completed, it is deflated for a minimum of one minute before the next type of exercises are started. Other: ACL Reconstruction rehabilitation.
Does BFR increase muscle growth?
Studies suggest that BFR stimulates muscular development through an increase in metabolic stress, muscle fiber recruitment, cell swelling, and protein synthesis.
