​Wearable tech heart rate tracking is ‘incredibly accurate’

Wrist-based heart rate monitors get a bad rap, especially when it comes to the new wave of devices from the likes of Fitbit, Mio and Apple.  But Professor Greg Whyte has told Wareable that, in reality, the criticism levelled at wearable and heart rate tracking accuracy is unfair. And while it should be noted that he’s an ambassador for Fitbit, Whyte is a highly respected sports performance scientist, a former Olympic athlete and leads the Centre for Human Health & Performance at Harley Street in London – so he has little to gain by spouting any propaganda in his field.   “It’s very easy to knock wearable tech by saying it’s not accurate,” he told us in an interview at his lab. “There is a lot of noise on them, but actually there is a lot of noise created by humans – particularly during exercise,”  Whyte has seen first hand the differences between the data from top scientific tech and consumer grade wearables. And somewhat surprisingly, he gives the likes of the Fitbit Surge and Apple Watch a glowing bill of health.   “For what they are and what they do, wearable tech is incredibly accurate. The signal to noise is such that the data we’re getting is quite good.”  –  But what do you do if you notice that over the last week your heart rate has gone up? Well, by taking it in the morning Whyte says you can rule out food or drink, and it’s time to start watching other parts of your life.   “Changes in waking heart rate is unlikely to be anything to do with diet or caffeine. It’s a global assessment of your physical state. If your heart rate is up by a significant amount, what could the cause be?”  “If you’ve been drinking heavily the night before then you know why. If you have had a very poor night’s sleep because a of a host of reasons like noise etc, than that could be a cause – and then it might be an issue with your ‘sleep hygiene’ so your blackouts aren’t good, you haven’t got the right bed, the right linen. It could be that you’re in the middle of exams, buying a house, something stressful in life.   “Use it as a starting point, identify what it could be and then address the issues.”
