No One Talks About This – What You Just Learned Was Not Exactly BFRT Science, It Was More Product Guidelines Than Science!

This is based on information from a text I received yesterday about a course at an industry meeting.

You just attended an industry meeting and sat through the session on blood flow restriction training — or BFRT. Tell me honestly: What did you actually learn? Was it real BFRT science… or mostly product guidelines disguised as science? Or some confusing mix of both?

It bothers me — and it should bother you too — that some individuals teaching BFRT don’t seem to know whether they’re sharing actual science or just product knowledge.

The Clear Line That Too Many Cross

It’s perfectly fine to teach product knowledge. But you must label it clearly. For example, you should provide a disclaimer up front that your course is sponsored by or based on information provided by the specific product. You should also label slides like this: “This information is based on instructions provided by Vendor ‘X’.  If you based it on a single study, then note the study and better yet read the study to check for bias.

Broad, misinformed, inaccurate, and misleading teaching is to tell or suggest to your students or audience that: “To set initial pressure you should use 85% of AOP.”

That’s a vendor instruction when using their specific gear — no more and will apply to only the users of that specific equipment. If educators skip the disclaimer and present it as “This is how BFR is done,” they’re doing a disservice to themselves and their audience.

Why This Distinction Matters

If you do more research, you would find that across different BFRT studies using different devices, initial pressure settings can vary wildly — from as low as 40 mmHg to as high as 300 mmHg. That’s because cuff design, width, and pressure efficiency vary significantly by vendor. Studies show successful outcomes across a wide range of pressures and percentages, proving there’s no single “magic number.”

No matter your starting pressure, the real key is observation and feedback to dial in the actual working pressure. Effective BFRT always includes occlusion, resistance, and duration.

Factors like body position, cell swelling, muscle contraction, activity level, resistance load, and session duration all dynamically affect cuff pressure during use. Initial pressure is simply a recommendation — nothing more. If the course you attended never taught you how to use real-time feedback, you haven’t been well taught.

Important Note: Want to dive deeper into setting effective pressure, the randomness of Arterial Occlusion Pressure (AOP) and the risks of relying solely on initial pressure settings such as safety, comfort, adherence, and potential injury, check our other posts on the topic.

Spot the Red Flags as an Audience Member

Spotting bias is easier than you think if you have a broad base of BFRT knowledge. Watch for slides or statements about setting initial pressure like:

• “Measure AOP and set the cuff to 80% of AOP.”

• “Let the cuff set the measurement for you.”

Identifying Vendor Specific Instructions.

Using instructions on how to set pressure is not the only issue. The same issue appears with guidelines such as frequency of use recommendations. You’ll often hear “Use BFRT 2-3 times per week.” Many studies use this frequency, but they’re heavily influenced by manufacturer guidelines that are driven by cost, remuneration, and equipment complexity.

Can using BFRT 2-3x per week be effective? Sure, but it’s far from optimized and will deliver minimal benefits when compared to ideal use guidelines.

Here’s why:

1. Research shows accelerated, superior results with 2x daily BFRT protocols.

2. Other benefits like pain moderation can last 24-48 hours after use— meaning 2-3 sessions per week leaves you with normal pain levels for 2-4 days out of 7.

Looking outside of studies about BFRT, endocrine research reveals that elevating hormone levels a minimum of 3x per week can trigger a sustained natural rise in those hormones.

These are just a couple of the statements or instructions that signal knowledge that relies more on product and less on actual science. In the future we will discuss more.

Want one-time benefits, follow old data, but if you are after sustained benefits look to new science, understand how BFRT really works, and expand your research to related science.

Educators and Presenters

If you’re an educator in the BFRT space, you owe it to yourself — and your audience — to go deeper than product-level knowledge.

If you’re primarily teaching a single vendor’s course and the studies they highlight, I urge you to expand your understanding. While product-specific training can help you use that tool more effectively, it does not optimize BFRT for your own training or your clients. It is also not the only effective solution.

If you are a paid endorser for a specific product, disclose it. If your knowledge is heavily reliant on one company’s curriculum, be transparent about that. Never present product training as comprehensive BFRT science.

Teaching product knowledge as if it represents the full scope of BFRT severely limits its reach. Done correctly, Blood Flow Restriction Training has the potential to benefit over 90% of the rehabilitation, fitness, and athletic performance markets — by accelerating recovery, preserving joint and tissue health, and delivering a real competitive edge.
