Pneumatic vs. non-pneumatic cuffs

Generally we see two types of cuffs/bands being used for BFR training: pneumatic and non-pneumatic.

NON-PNEUMATIC CUFFS:
This category includes several materials used to restrict blood flow, most commonly polyester fabric bands with a plastic clip for adjusting the size. Some people also use tight elastic bands around their limbs.

While these materials are cheaper, they have their reasons for it. Since they cannot be inflated and therefore cannot accurately measure the pressure or the precise percentage of restricted blood flow, they can cause more harm than good.



Their main drawback is the inability to objectively measure the degree of blood flow restriction, which can lead to unknowingly applying either too much or too little pressure. Too much pressure can cause harm to the body, while too little may not produce sufficient metabolic changes, making the exercise ineffective.

PNEUMATIC CUFFS:
The common feature of all pneumatic cuffs is a valve and an airbag, which can be inflated with a manual pump or an automated system. With pneumatic cuffs, we can control the applied pressure in each cuff. The advantage of this is that we can objectively achieve the desired degree of blood flow restriction, allowing us to adjust the pressure in each cuff individually. Another advantage is that it is easier to monitor and progress BFR training.



Current recommendations are stating to start with lower pressures and gradually increase them throughout rehabilitation or training processes, ensuring they never exceed 80% AOP. Additionally, pneumatic cuffs are often more comfortable to use, as they are filled with air.



In summary, pneumatic cuffs are safer, more comfortable, and better for increasing the intensity of BFR training. Their only downside is their higher cost due to their more complex composition. For this reason, BFR.SI aims to provide affordable BFR cuffs. You can order them here.
