Activities and health
PAI
PAI is used to measure a person's physiological activity and reflect overall
physical condition. It is calculated based on a person's heart rate, the intensity
of daily activities, and physiological data.
By maintaining a certain intensity of daily activity or workout, you can obtain
your PAI value. According to the research results of the HUNT Fitness Study*,
people with a PAI value greater than 100 are more immune to cardiovascular
diseases and have increased life expectancy.
For more information, open the Zepp app and go to PAI > PAI Q&A.
*The HUNT Fitness Study is a sub-project of the HUNT study, led by
Professor Ulrik Wisloff at the School of Medicine, Norwegian University of
Science and Technology. It has lasted over 35 years and involved more than
230,000 participants.
