To put it bluntly, being strong makes life easier. Humans don’t have the ability to create more muscle fibers (hyperplasia), so in order to get stronger we have to work tediously to increase the size of our existing muscle fibers (hypertrophy). According to the American Academy of Sports Medicine, gaining strength through hypertrophy takes 8-12 weeks of moderate to high intensity resistance training (>65% of your one rep max) utilizing 8-10 upper and lower body exercises at a rate 2-3 times per week.
A relatively easy formula to follow; right? Well, what happens when you are recovering from an injury and can’t safely use loads heavy enough to improve strength and size? Or when you’re an athlete who is in-season and can’t tolerate the drop in performance associated with the muscle soreness that follows heavy lifting?
Up until now those have been troubling questions for medical professionals and strength coaches alike. However, there is a new tool with over 160 peer reviewed research studies and documented success across the military, college, and professional sports arenas; something that is creating increased size and strength in as little as two weeks and is completely changing the game of how professionals approach rehab and sports performance…Personalized Blood Flow Restriction Training (PBFRT).
What is Personalized Blood Flow Restriction Training and How Does it Work?
PBFRT is the brief and intermittent use of a tourniquet in order to restrict the amount of blood flow from coming into your limb (arterial flow) while performing low-load resistance training. There are numerous types of blood flow restriction devices available, but the gold standard occlusion device is the Delphi Personal Occlusion Tourniquet. The Delphi Personal Occlusion Tourniquet the only device have FDA approval to be safely used for medical use and is essentially a modified surgical tourniquet that contains a doppler system. This doppler system allows so you read a person’s arterial flow in live time, so you know exactly how much blood you are occluding, and it will adjust its pressure automatically throughout an exercise to maintain a designated percentage of occlusion that is personalized to each individual person.
The way PBFRT works is it reduces the amount of oxygenated blood reaching a working muscle in order to trick your body into thinking it’s working at a higher intensity than it actually is. By using this form of engineered suffering you’re able to use extremely light resistance and still get the same increases in size and strength as lifting at higher intensities with heavy weight! Exactly how this happens is laid out below:
