PAI’s algorithm is based on the HUNT Fitness Study, which was conducted by the Faculty of Medicine at the Norwegian University of Science and Technology. Professor Ulrik Wisløff, one of the world’s leading scientists in Exercise in Medicine, developed this study. The HUNT Fitness Study followed 45,000 participants over 25 years. It established how much physical activity you need to live a longer, healthier life and to help prevent heart disease mortality.
PAI analyzes your active and resting heart rate data, age, and gender to provide a single measure that motivates users to be more physically active. PAI adapts to diverse lifestyles, making activity goals highly individualized and realistic to attain. You can choose any activity that gets your heart rate up and your PAI Score above 100 to notice optimal health benefits. Everyone’s goal is the same - to stay above 100 - but what it takes to reach that goal is personalized.
Published studies have demonstrated evidence associating a PAI Score of 100 and above, with reduced risk of mortality across many cohorts and sets of data.
PAI reduces your risk of heart disease mortality
Why is it so important that PAI is backed by science? Because low levels of physical activity contribute to over 5 million deaths each year. Metrics we are currently using, like 10,000 steps or 30 minutes of activity, are simply not working.
The HUNT Fitness Study found that people who consistently keep their PAI Score over 100 could be less at risk of mortality from hypertension, heart disease, and Type II diabetes.
The American Journal of Medicine
The PAI metric was published in The American Journal of Medicine with the conclusion that PAI can provide people with real insight into how much exercise they need to live longer, healthier lives.
PAI was also validated as a metric that can be used with devices with heart rate sensors for people to monitor their exercise levels for maximum health benefits.
PAI Combats Sedentary Lifestyle
A study in the Progress in Cardiovascular Diseases found that PAI can even combat the risk of cardiovascular disease and other lifestyle-related diseases regardless of sedentary lifestyle, such as sitting at a desk for up to 7 hours a day.
The study found that sitting for long periods of time will not increase your risk of cardiovascular disease as long as you maintain a PAI Score of 100 or more.
