About

A high physical fitness can prevent cardiovascular disease. Which form of exercise training is efficient at improving fitness is well known. The challenge is to get people to do it. Personal activity intelligence (PAI) is an algorithm developed for this challenge. It gives a score that tells the users whether they are active enough to achieve the maximum health benefit of exercise based on their heart rate. It has been shown that people who obtain 100 PAI a week have less cardiovascular disease, but intervention studies showing that PAI can improve physical fitness are so far lacking.

Step counters have received a lot of attention and 10 000 steps a day is a common recommendation, but little is known about the physiological adaptations to this intervention.

This study will compare the effect of physical activity with a value of 100 PAI points a week with 10 000 steps a day in healthy, but overweight (body mass index > 25) participants between 30 and 50 years of age.

Enrollment: 21 patients

Sex: All

Ages: 30 to 50 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Previous myocardial infarction
• lung disease
• heart disease
• uncontrolled hypertension
• kidney disease
