Fit Cuffs - BFR Training: Brand-new Progressive Web App

Описание: www.fitcuffs.com

We have just released the brand-new progressive web app “Fit Cuffs Traning”, with online and offline availability by downloading it to your phone just as a standard app from google store or app store.

So check the video on how to register a user, calculate pressure, tab in Limb Occlusion Pressure (LOP) and the last 10 s. on how to download it for offline availability. You can access the app from the homescreen just as an any other app on android devices and Iphones.

We have developed the algorithm from the comprehensive science and data on the predictors of Limb Occlusion Pressure (LOP), for you to enjoy Effective, Save and Convenient BFR Training.

We do not recommend to use arbitrary pressures, neither do we recommend a default pressure, though 80 mmHg and 100 mmHg for the upper and lower body, respectively, would be applicable for about 90% of all people.

Our goal pressure extracted from the algorithm is 40-70% LOP and 50-80% LOP, for the upper and lower body, respectively. Currently, the new progressive web app “Fit Cuffs Training” can predict this goal pressure for +95% of all people.

From the comprehensive research articles, it seems that limb circumference can explain about 50-70% of the variance in LOP. But the width of the cuff is actually the most important factor to consider, that is also why this App is only applicable for Fit Cuffs®.

Thigh circumference is undoubtedly the biggest anthropometric predictor of arterial occlusion, but other factors are also of importance:

It seems that both gender, age and body composition influence the percentage of blood flow that is restricted. That is why these predictors are included in the algorithm, along with training condition, as we find this of importance for Ratings of Perceived Exertion (RPE).

So, when LOP is not assessible, we recomend to use calculated pressure.

Every time you tab-in LOP and calculate a corresponding pressure for either upper or lower body, you actually help us to improve the algorithm in the future.

".. cuff pressures should be largely based on thigh circumference and not on pressures previously used in the literature.” (Loenneke et al. 2012)
