Best Fitness Tracker with Heart Rate Monitor Review 2017
When fitness trackers first came out a few years ago, they were, essentially glorified pedometers. Over the years, however they have become more sophisticated. Today, people want more and more advanced features packed into their devices.
Heart rate monitoring is a key fitness component which people are now expecting to find in their activity tracker. Yet, not all fitness trackers offer heart rate monitoring. Among those that do, the reliability can fluctuate widely. So, we went in search of the 5 best wrist heart rate monitors of 2017.
The most reliable, easy to use and and all round best heart rate monitor of 2017 we came across was the Adidas FitSmart. Coming in at a close second was the Mio Alpha 2. Rounding out the top 5 activity trackers with heart rate monitors of 2017 were the FitBit Surge, The Garmin Vivofit 2 and the Polar Loop 2.
How Accurate are Fitness Tracker Heart Rate Monitors?
We’ve all seen people with those chest strap heart rate monitors. Because these units are worn directly over the heart , they are generally pretty accurate. However, they are also weildly and cumbersome. Fitness trackers with heart rate monitors are far more user friendly - but are they as reliable?
Activity trackers use an optical sensor that is placed on the wrist. It is not near your heart, so it is not sensing the electrical activity within your heart. Rather, it is sensing the flow of blood through your capillaries. It measures one pulse with each heart beat.
When studies have been done with a range of optical heart rate monitors against EKG heart rate monitoring, results have varied widely. There is usually a difference of between 25-45 beats per minute. Quite a few monitors will not be able to measure your heart rate while you are exercising. It may take up to two minutes after you stop before it can get a reading. This is obviously not going to do you much good when trying to monitor your active pulse rate.
According to Dave Wright, CEO of MyZone, a delay of anything more than a couple of seconds in an activity tracker with heart rate monitor makes the data irrelevant . . .
"Anything more than a one or two second delay isn't acceptable. The reason being that HIIT sessions are about pushing people to the limit. If you're doing 10-20 second intervals and there's a delay of 10 seconds, it's beyond unacceptable.”
The harder and faster you exercise, the less accurate your heart rate monitor will be. That’s because the majority of activity trackers use heart rate monitors that measure blood flow through the wrist capillaries optically. When the blood flow speeds up beyond about 160 beats per minute, it becomes very difficult to get an accurate reading.
Another problem with monitoring heart rate from the wrist is that this area of the body has less tissue, more bones, more tendons and not as great a blood flow as other areas. This also impacts upon accuracy.
The situation becomes even worse when you are trying to monitor your heart rate during exercise. When doing Cross Fit or training with weights, the head and the upper arm are ideal pulse monitoring sites. The wrist is not.
Optical wrist monitoring is, however, a convenient way to monitor heart rate. It has gotten better over the years, but still has a way to go. If you’re a serious trainer, you don’t want to be relying on optical activity tracker pulse monitors for your exercise data. Members of the general fitness community, however, can use them with relative confidence.
