We’ve worked alongside scientists and fitness experts to ensure our TechWear is safe, comfortable and easy-to-use. We’ve analysed the data to design our straps to the exact width, placing them at the exact position and using the most appropriate materials to ensure the safest possible occlusion. When it comes to scientific credibility, no other brand goes to our lengths.

And now we’re going even further. It gives us great delight to announce our first scientific study into BFR, performed in collaboration with Queen Mary University London.

The desire to contribute to the scientific literature around BFR can be traced back as far as the birth of our company. By that stage, our founder Dr. Warren Bradley had already published numerous journal articles and book chapters on the topics of human physiology and performance nutrition. As he turned his attention to BFR, he developed a desire to add to his growing portfolio of academic research. He decided that he wanted to improve the knowledge and understanding of a truly transformative training technique.

Now, more than ever, we believe it is vitally important to explore the capability of BFR so that the scientific literature can evolve still further. Research is constantly developing to produce new ways of thinking that lead to innovative uses of BFR. That creates an incredible opportunity for us to be at the forefront of a quickly evolving area of academia, ultimately contributing to make BFR an accessible, well-understood way to train, recover and rehabilitate.

What could be more exciting?

Our initial contribution to scientific literature will centre around the use of our unique and patented integration of BFR Tech. We will work with Queen Mary’s University to determine the feasibility and efficacy of Hytro TechWear.

To do this, our study will be run by two fourth year medical students at Queen Mary University, with supervision from Dr. Brad Neal of Queen Mary University and Pure Sports Medicine. For a six-week period, they will monitor the progress of 30 participants (15 male and 15 female) who have never used BFR before, and who will undergo two Hytro BFR training sessions a week.

After a brief familiarisation period, participants will be asked to pull the straps on their TechWear to a 70% level of perceived tightness and perform exercises – push-ups, banded rows, banded bicep curls and banded tricep extensions – for 4 sets of 30:15:15:15 repetitions with 30 seconds of rest between each.

After each session, they will then record their perceived rate of exertion from the training along with their feelings on how comfortable they are with the exercises and whether they believe they are suffering any adverse effects.

Subsequent testing will take place on the participants to assess changes in strength and muscle mass. Tests will include a strength endurance test using a validated push-up protocol, and jump tests. These will be carried out alongside physical measurements such as body mass, height, muscle girth.

Ultimately it is our aim from the study to educate people on the benefits of BFR, and to showcase why Hytro is the most convenient and effective way to perform BFR. Specifically, that Hytro is a safe and effective tool that makes the proven benefits accessible and convenient.

We are already in talks regarding further scientific research using Hytro TechWear  – this time with Liverpool and Liverpool John Moores Universities. This will see us conduct clinical research using Hytro TechWear for home-based rehabilitation, for example, cardiac rehabilitation following traumas such as heart attacks, heart surgeries or stent procedures.

It’s a very exciting time for all of us here at Hytro. And we’re thrilled that our TechWear is being used to further the research into Blood Flow Restriction Training. At home, you can conduct your own research, try Hytro as part of our 30 day challenge and feel the difference for yourself.

So strap in, feel the pump and embrace the transformation. Join us in unlocking the scientific secrets of BFR tomorrow, today.
