Introducing the LOP Device (V1.1)

📵 The most noticeable improvement of this upgraded gadget vs the original Bluetooth Device, is that it no longer need an external hub/phone.❕️

📺 In display you will find the rather simple instructions for the new device. That is swift, reliable and valid measurement of Limb Occlusion Pressure (LOP).

💡 This appliance is simply more convenient compared to the previous version, as you do not have to worry about installing and running an app on your phone using bluetooth tech.

🚦 The V1.1 has a small LED display that guides you through the process of assessment and shows LOP.

📲 The app connection is kept, but only as an adjunct. This can be of relevance for easy tracking and saving multiple users consecutive measurements!

♻️ The most noticeable advantages spec of the LOP Devices vs other brands is the use of a standard pressure gauge for inflation.

🔋 This becomes apparent during sup LOP inflation pressures, as relative high power output is needed to reach pressures about or > 200 mmHg! Some people simply prefers not to have yet another techy device that needs frequent recharging or instant power supply as either is necessary for the automatic BFR devices.

💡 To accommodate this issue, the high-powered process of inflation is obviously kept manual while operating the LOP Device.

⚙️ So, the only hardware needed within the LOP Device is a small processor, a few RAMs, pressure sensor (oscillometrics), LED display and a lego brick-sized lithium battery.

♾️ Nevertheless, this basic setup means near indefinite capability as about 1000 measurements on a single charge!
Yep, You should definitely not worry about re-charging anytime soon.

🗯 Dare ventures, with this small piece of tech, it has never been more easy to detect the pressure needed for safe and effective BFR stimuli!

The Science Behind the Fit Cuffs Pressure Calculator V2

Does auto adjusted blood flow restriction (BFR) training improve muscle growth and strength compared to fixed-pressure cuffs? In this first 8-week within-subject study using the Fit Cuffs BFR system, researchers found no meaningful differences in hypertrophy, strength gains, or perceived discomfort between autor and non-auto conditions. When pressure was prescribed relative to limb occlusion pressure (LOP) and training variables were standardized, both approaches produced significant improvements. Here’s what coaches, clinicians, and lifters need to know about auto vs fixed-pressure BFR.

Figures 2 and 3 display grouped scatter plots comparing autoregulated (AUTO, gray circles) and non-autoregulated (NONAUTO, red triangles) blood flow restriction training before (Pre) and after (Post) an 8-week intervention. Figure 2 shows significant increases in rectus femoris and vastus lateralis muscle thickness at 30%, 50%, and 70% femur length in both conditions, with no differences between groups. Figure 3 shows significant increases in rectus femoris cross-sectional area (50% and 70%) and 1RM strength for single-leg squat and knee extension in both conditions, again with no between-group differences. Asterisks (***) indicate statistically significant pre-to-post improvements.
