Fitbit’s analysis shows resting HR dips after 40 – News | GadFit

February 18, 2018

If there’s one thing Fitbit has over Apple, it’s the numerous years of data from their users which they can crunch and see trends from; anonymised of course.

So 2 days ago Fitbit revealed an analysis of their global users including this resting HR graph against age. And surprise surprise, resting HR dips after age 40.

As to what causes this trend, Fitbit didn’t offer any conclusions. I think most of us would know that , generally when free of illness, a lower resting heart rate is indicative of good cardiovascular fitness

We could speculate that after hitting 40, most people might want to take things a little easier having given their all to their work the first 20 years of their lives after 20.

Or perhaps, 40 might be the age when people become more concerned about health and start paying attention to staying fit and all. We’ll never know for sure until Fitbit follows up with another of their analysis.

The other point of interest highlighted in Fitbit’s analysis is that of all the Fitbit users worldwide, those in the United States and Singapore had the highest average resting heart rate at 65.9 beats per minute (BPM).




Again, no further analysis was provided as to why this may be so.

Coincidentally Singapore has one of the highest number of yearly hours clocked working at about 2246 hours (for employed residents based on 2017 figures from Ministry of Manpower); pretty close to the OECD’s list where Mexico is tops at 2255 hours a year.

In the sleep department, our teenagers may not be getting enough sleep and our adults aren’t faring much better.

Long work hours coupled with lack of sleep seems like a plausible formula for the highest average heart rate in all of Fitbit’s millions of users. Neverthless, all speculations at best no doubt.

Comparatively, the lowest average resting HR as captured by Fitbit is those of users in Italy at just 61.8 bpm. Italians are certainly getting more sleep than Singaporeans and the number of hours worked per year based on 2016 OECD data is 1730 hours; nearly 20% less than Singapore’s.

    also after about 40 we all experience muscular atrophy (wasting). Perhaps it is linked to this in some way.
