Fitness trackers allow users to collect, manage, track and monitor exercise-related activities, such as distance traveled, calorie intake, quality of sleep and heart rate. We've come a long way since the pedometer. Nowadays, smartwatches and portable fitness trackers not only record steps and mileage, but they also monitor sleep patterns, heart rate, calories burned, and blood oxygen levels. In recent years, new models can track AF (atrial fibrillation), an irregular heart rate that can cause a stroke.
A fitness tracker is a device that a person can use throughout the day to track various body parameters. This cardiovascular fitness score is a measure of your cardiovascular status based on your VO2 max (the maximum amount of oxygen your body can use when you exercise at maximum intensity) and can be found in the heart rate section of the Fitbit app. Fortunately, this metric is another basic statistic for fitness trackers, so you should find it in just about every option that appears on your shopping comparison list. Wearable technology refers to devices, such as fitness trackers or smartwatches, that people can wear throughout the day.
If malicious actors manage to hack the servers of a fitness tracking company, they could sell the information they steal or try to return it to the fitness tracking company.
