What is PAI and why is it so important?

In the latest wearables arrived on the market with the Xiaomi and Amazfit brand, we find the presence of the PAI value, but perhaps some of you still don't know what it is. This value is in addition to the other collected by the wearable smart, taking for example the recent Xiaomi Mi Band 5, the monitored data is more accurate by 50% compared to previous generations, showing heart rate, sleep monitoring and pedometer to name a few.

The PAI value was introduced by Huami on their Amazfit devices and basically we could define it a personal indicator of physiological activity. In other words, it's a value that tells you how healthy you are in terms of physical activity or if you need to improve.

Everything you need to know about the PAI index of your fitness trackers

PAI is the English acronym for Personal Activity Intelligence and consists of an algorithm that, based on various data, returns a result that represents your physical condition. In particular, the data used by this function are the heart rate and other personal data such as weight or gender, therefore PAI is a personal index that differs with the same data collected by a person who weighs 100 kg from one that weighs half.

The value returned by the monitoring is based on weekly activity, so each week your fitness tracker will give different results that increase on a daily basis. The PAI value fluctuates between 0 and 125: according to the developers, the ideal would be to always reach a value of 100 or higher. In this sense, people who reach this value are less subject to risk of cardiovascular diseases and their life expectancy increases by about 8 years compared to people who do not reach this score.
Therefore, always keeping your PAI index under observation, we can increase it by carrying out physical activity and sports in general, in order to increase the heart rate, thus burning the fats that turn into weight loss. The higher your heart rate, the more PAI points you will get. This does not mean that you have to break your heart, but a simple activity such as walking and / or cycling on a daily basis, as well as using the stairs instead of the elevator, allow you to receive a score of at least 75, reaching the optimal PAI value of 100, in no time.

But be careful, because the PAI index only works if the wristband heart rate monitoring is turned on on your device. To turn heart rate monitoring on or off, you need to do the following:

  • Open the Mi Fit / ZEPP app on the smartphone you have associated with your wearable;
  • Go to the Profile section of the app and select your wearable;
  • At this point, scrolling through the options, you will see the item for enabling automatic heart rate detection, which to better calculate the PAI index must be set to a frequency of at least 5 minutes.

Well, now that you know what PAI is and how it works, you are ready to keep in training. We then recall that the PAI value is not exclusive to Mi band 5 but now present on all Huami devices and therefore Amazfit series, with the exception of the most obsolete wearables, such as the first generation Bip d. And which smartwatch do you rely on for the collection and monitoring of your fitness data?

Nerd, Geek, Netizen, terms that do not belong to me. Simply myself, technology lover and provocative as Xiaomi does with his products. High quality at fair prices, a real provocation for the other most famous brands.

Also ich finde die PAI total demotivierend. Ich geh meine 12000 Schritte am Tag, mach meine 45 Minuten Tai Chi, meditiere ne Stunde, und bekomme dafür in der Woche manchmal nicht mehr als 9 Punkte. Aus PAI-Sicht könnte ich manchen Tag (weil manchmal bekomm ich auch keinen PAI-Punkt) genauso auf der Couch sitzen und Chips in mich reinstopfen. For 100 Punkte müsste ich wohl 100000 Schritte am Tag gehen und 8 Stunden Tai Chi machen. Ich hab sie daher von meiner Uhr runtergeschmissen.

Sie müssen am Berg gehen oder leicht joggen. Wenn der Puls nur minimal erhöht ist, wie beim gehen, dann bringt das für Pai wenig !!
