Fitness Trackers Aren’t That Accurate, Study Claims


They have a fairly simple purpose – to track the progress of people working out and to encourage them by giving them accurate data, for instance, how many calories they’ve burned during a particular exercise. Unfortunately, it seems that these trackers aren’t that accurate at all.

In fact, kinesiologist Yang Bai led a research at Iowa State University and found out that these trackers can give some pretty false readings when dealing with specific exercises. The participants of the research were asked to wear the devices while performing three activities – 25 minutes of aerobic activities like running, several minutes of strength training and 20 minutes of using a computer or reading.

To begin with, all fitness trackers showed different results for the activities, and it was very hard to discern the results for individual activities. However, they varied even further when monitoring sedentary activities, with the differences in results going up to 30 percent; but in the end, the worst feedback came from the resistance activities, a whopping 32 percent.

We’re not saying you should throw your fitness trackers in the trash – just pay attention to your body, and don’t think that the little number on the display should be your only guide.
