![]() However, not everyone has a spare $300 to spend on a glorified blood pressure cuff. You either fill them up with air using a little palm pump, or you can have it done automatically by an attached or wireless computer. Tell Me How to Best Use ThemĬlearly, those pneumatic cuffs I mentioned in the opening paragraph are the best way to go when using BFR training. ![]() ![]() Swing 1000×409 88.8 KB Enough With All That. At that point, they fuse with mature muscle cells and donate their nuclei and help with repair and growth. Satellite cells are little baby muscle cells that hang around the basal lamina of muscle cells, waiting to be called in after a muscle-damaging bout of training. This process, like it sounds, involves the accumulation of fluid in the blood-flow restricted limb, thereby stressing the cellular matrix and activating “intracellular signaling pathways,” which leads to growth.Īside from those mechanisms, there’s also evidence that BFR training enhances the satellite cell response to training. These lingering metabolites cause type 2 muscle fibers to be recruited earlier than they might with free-form exercise.Īs these metabolites and fatigue increase, muscle activation increases and anabolic processes kick into gear. METABOLITE-INDUCED FATIGUEīFR training, like conventional training, causes metabolites like lactate hydrogen ions, ATP, and inorganic phosphates to be formed, but the band(s) trap all that metabolic gunk in the limb. Beyond that, BFR seems to employ two distinct underlying mechanisms to facilitate growth: 1. Growth is still mediated by mTOR, but mTOR and its effects kick in earlier and to a greater degree when BFR is employed. The usual rules determining hypertrophy still apply, though. You can use lighter loads and they’ll presumably work just as well as heavier loads. This causes the blood in the limb that’s wrapped to pool, which of course limits oxygen delivery and subsequently reduces the time it takes to reach muscular failure. In general terms, BFR uses bands or straps to partially reduce arterial blood flow while completely shutting off venous blood flow. Legs 1000×409 110 KB How the Hell Does BFR Work in the First Place? In it, they discuss how they think it works, including how and when to best incorporate it in your training.įollowing are some of the highlights from the paper. That’s changed, though, as occasional T Nation contributor Brad Schoenfeld, PhD, and his colleague, Nicholas Rolnick, MS, just published a research-based guide to BFR training. If you were instructing someone on how to practice auto-erotic asphyxiation and you gave them that kind of vague advice, I’m pretty sure you’d find that person dead in the closet, a noose around their neck, pants down around their ankles, and eternally draped by a shroud of shame and humiliation.Ĭlearly, there just wasn’t enough good info on the subject. “They should be tight, tight enough to impede venous blood flow, but not arterial blood flow.” I’ve always had the option of trying BFR training using cheapo, low-tech stretch bands instead, but the instructions on how to incorporate them in my training and how tight to wrap them for best effect was vague: I better be ready to whip out the paddles!” ![]() “Oh look, that poor man has to check his blood pressure between sets. ![]() I’ve always wanted to experiment with BFR (Blood Flow Restriction) training but I didn’t want to fork out the dough for one of those pneumatic cuffs that would surely make the cute girl who works behind the desk run off to see if the gym’s defibrillator is charged.
