The market is quickly becoming over-saturated with health tracking consumer tech, which in my opinion is a positive thing. We should all be a little aware of our health and how our body is operating daily. It is also vital for cardiac patients who have become more reliant on this technology, that claims of accuracy are, well, accurate.
However, a new report challenges the exactness of four popular fitness trackers on the market against a chest strap monitor connected to an electrocardiogram (EKG). The research letter, published by JAMA Cardiology earlier this week, put the Apple Watch, Mio Fuse, Fitbit Charge HR and Basis Peak against the Polar H7 strap, a first of its kind report according to the authors.
The test recruited 50 people, averaging about 37-years-old (give or take 10 years) with a mean body mass index of about 23.5%, which is just under the overweight BMI of 25% but still within an objectively healthy fitness level. Heart rates were monitored at rest all the way to 6 mph on a treadmill.
