![]() When used during exercise, BFR bands create an environment in which the muscles are forced to work harder than they would without the bands. The amount of pressure required to achieve the desired effect depends on the individual but is typically in the range of 20-80mmHg. For instance, a band that is 2 inches wide will provide more pressure than a band that is 1 inch wide. The level of pressure is typically determined by the width of the band, with wider bands providing more pressure. How Do BFR Bands Work?īFR bands work by applying pressure to the muscles and veins in the extremities, which in turn restricts blood flow to the working muscles. This makes them an ideal tool for those who are looking to maximize their workouts but may not have access to heavy weights or are limited by injuries. By doing so, BFR bands allow you to achieve a higher level of muscle fatigue and pump, without having to lift extremely heavy weights. 4 Are Blood Flow Restriction Bands Safe?īlood flow restriction (BFR) bands are a type of equipment that can be used to safely and effectively restrict blood flow to working muscles during exercise.3 How to Use BFR Bands for Muscle Growth?.1 What Is Blood Flow Restriction Bands?.This will help standardize this type of treatment modality for future studies.īlood flow restriction training knee muscle atrophy quadriceps strengthening surgery. Lastly, BFR protocols need to be further investigated to determine which provide the best patient outcomes. However, future research should examine the effects of preconditioning with BFR before surgery. The results of this analysis show that BFR in the postoperative period after knee surgery can improve quadriceps muscle bulk compared with a control group. This is the first systematic review and meta-analysis to study the effects of BFR in patients undergoing knee surgery. ![]() Last, preoperative BFR training did not show any significant clinical benefit between the 2 studies. It should be noted that 4 of the included papers in this review reported increases in clinical strength when using BFR in the postoperative setting. However, there were no significant differences found for patient-reported outcome measures between the included studies. The results demonstrated that BFR use in the postoperative time period can lead to a significant improvement in the cross-sectional area when quantifying muscle atrophy. For the meta-analysis, including 4 studies, the primary outcome variables included the cross-sectional area of the quadratus femoris muscle group assessed with magnetic resonance imaging or ultrasonography, and patient-reported outcome measure scores. Two studies specifically assessed BFR use in the preoperative time frame. Selected studies subsequently underwent data extraction, methodological quality assessment, and data analysis.Įleven studies were eligible, including anterior cruciate ligament reconstruction (n = 10) and knee arthroscopy (n = 1). Search results were limited to those assessing BFR training in patients undergoing knee surgery published in a scientific peer-reviewed journal in English. This systematic review and meta-analysis of peer-reviewed literature was conducted using PubMed, Embase, and Cochrane databases from 1980 to present. Systematic review and meta-analysis Level of evidence, 4. We hypothesized that BFR, before or after surgery, would improve clinical outcomes as well as muscle strength and volume. ![]() The purpose of this study was to conduct a systematic review and meta-analysis to examine the effectiveness of BFR training in patients undergoing knee surgery. Furthermore, the effectiveness of BFR training in patients undergoing knee surgery has been investigated to determine if its use can improve clinical outcomes. Blood flow restriction (BFR) training has been shown to have beneficial effects in reducing quadriceps muscle atrophy and improving strength in patients with various knee pathologies.
