A new approach to activity measurement what is the PAI coefficient

However, in 2010, Ulrik Wisløff and Valencell began studying a completely different approach to physical activity and developed a new way to measure it Personal activity intelligence (PAI).

1. PAI coefficient what is it?

Monitoring devices, such as watches or sports belts, collect information about heart rate and intensity of exercise. However, it should be noted that the PAI monitoring function is currently only available in Xiaomi branded watches. It is calculated on the basis of activity intensity and duration information taking into account other factors such as age, gender, body weight or general health. Based on these, the algorithm calculates a PAI that reflects the personalized impact of physical activity on health.

Interestingly, the activity required to achieve 100 PAI points may be different for each person and physical fitness plays a key role here. The recommended PAI level is at least 100 points per week. Walking, cycling, swimming, or even daily household activities, if they are intense enough, also increase this activity.

3. Why exactly 100 points?

Studies conducted by the Norwegian University of Science and Technology (NTNU) have shown that maintaining a regular PAI of 100 points per week is associated with a significant reduction in the risk of premature death and the development of many diseases.

4. Obesity, you know

The findings suggest that obese people who regularly engage in physical activity can reduce their risk of cardiovascular disease and other complications related to excess body weight. The PAI has been observed to be a very useful tool in motivating people with obesity to get physically active and achieve significantly better health outcomes (S.K. Obesity is one of the biggest health challenges of the 21st century. It is closely linked to complications. Regular exercise contributes significantly to heart rate and improves muscle mass, increases blood pressure, improves blood cholesterol control, and maintains healthy blood tissue, which significantly increases body fat levels, and helps maintain healthy blood cholesterol levels, as well as maintaining healthy blood sugar levels).

5. Heart disease is the most common type of heart disease

In addition, it may help to better control blood glucose levels, which additionally translates to reducing the risk of cardiovascular complications related to diabetes. Nauman et al. 2019). Regular physical activity in this regard contributes to improving heart and circulatory performance, lowers LDL-fraction cholesterol levels, regulates blood pressure, and reduces the likelihood of seizures and heart attacks. Therefore, maintaining an active lifestyle and achieving a higher PAI can play an important role in preventing heart disease and improving overall heart health (J.

6. The overall mortality

Nauman et al. 2022) Therefore, regular physical activity of appropriate intensity can be a key element in the long-term maintenance of good health and well-being (J. Research clearly shows that physical activity translating into a PAI score above 100 can have a significant impact on reducing overall mortality by improving overall health and reducing the risk of chronic diseases.

7. PAI monitoring is not for everyone

Persons with a tendency to perfectionism may be more prone to the negative effects of such an approach, such as fatigue, constant stress, or even guilt when their goals are not met. It is equally important to maintain a balance between physical activity and other aspects of life, and to listen to one's own needs and signals sent by the body to avoid injury and fatigue. Unfortunately, despite the many advantages of PAI monitoring, there are also some disadvantages to this activity.
