Activity trackers: Can they really help you get fit?

Comply with me on Twitter @RobShmerling

Currently, I’ve been checking the variety of steps I take every day. It’s not exhausting to do. My telephone tracks it with out me even asking it to. It additionally tracks the variety of flights of stairs I’ve climbed and the variety of miles I coated. And there are different choices: I may observe how typically I arise, what number of energy I’ve burned by being lively, and what number of minutes I’ve engaged in brisk exercise.

Even my employer has gotten into the act. As is widespread in lots of workplaces, one in all our hospital’s wellness packages has organized “strolling golf equipment” with groups evaluating and competing with one another primarily based on the variety of steps workforce members take every week. Some corporations provide prizes, monetary incentives, or reductions in medical health insurance premiums if an worker participates in such a program.

Why all this monitoring?

Know-how we stock round with us — our telephones, watches, or different devices — permits huge quantities of knowledge to be collected about us daily. It’s essential to needless to say there’s a function to all of this. The purpose of exercise trackers is to turn out to be extra conscious of how a lot (or how little) exercise we’re doing in order that we are able to make constructive adjustments. For the reason that well being advantages of bodily exercise — and the well being dangers of being sedentary — are nicely established, growing exercise is a well being precedence (or ought to be) for hundreds of thousands of individuals. Exercise trackers are the primary, um, step (sorry, couldn’t resist).

Do exercise trackers actually enhance well being?

My guess is that most individuals take without any consideration that exercise trackers are useful in selling extra bodily exercise, however that’s primarily based totally on assumption. That’s why researchers at Duke-Nationwide College of Singapore Medical College designed a examine to match full-time staff who used exercise trackers with those that didn’t. Every of the 800 staff enrolled within the examine paid the equal of $7 to enroll after which have been randomly assigned to one in all 4 teams for one 12 months:

  • use of a Fitbit Zip, a preferred clip-on exercise tracker (with fee of $3/week to proceed within the examine whatever the variety of steps taken)
  • a Fitbit plus a money incentive ($11 for taking 50,000 to 70,000 steps every week, or $22 for greater than 70,000 steps/week)
  • a Fitbit plus a fee to a charity (which was bigger with elevated exercise)
  • a management group that didn’t use an exercise tracker; this group additionally acquired the $3/week for participation no matter exercise ranges.

Researchers monitored extra than simply the variety of steps taken. Research individuals additionally had monitoring of extra vigorous train and bodily exercise, weight, blood stress, health ranges, they usually have been requested about high quality of life as nicely.

So, what did they discover?

First, the excellent news

The group receiving the money incentive elevated their day by day steps in comparison with the beginning of the examine. This group was extra lively than the management group at six months, and 88% of them have been nonetheless utilizing their Fitbits (in contrast with about 60% of the Fitbit solely and charity incentive teams).

Say it isn’t so!

When incentives stopped, just one in 10 examine topics continued to make use of the Fitbit. And after a 12 months, with incentives stopped, exercise ranges fell within the teams receiving an incentive in comparison with after they began. That is disappointing certainly, particularly contemplating that the individuals on this examine have been most likely extra motivated than most to give attention to their exercise ranges. They went to the hassle and expense of enrolling within the examine and agreed to place up with all of the monitoring. As well as, most individuals in the true world most likely don’t have any direct monetary incentives to keep up a sure stage of exercise every week.

This examine follows one other one from the College of Pittsburgh that discovered much less weight reduction amongst younger adults who used health trackers in comparison with those that didn’t.

What’s subsequent?

As expertise evolves and analysis gives extra details about what works (and what doesn’t), I feel we’ll see a brand new era of gadgets which might be extra personalized to particular person wants and medical situations. For instance, an individual with diabetes may monitor bodily exercise to supply details about methods to coordinate insulin injections and meals.

As well as, exercise trackers can do greater than merely spit out details about how lively you’ve been. An excellent instance comes from one other current examine wherein exercise trackers have been integrated right into a aggressive sport, full with signed commitments to particular exercise targets, an elaborate level system, and reliance on workforce cooperation and rewards. The examine discovered that these utilizing game-based exercise trackers have been extra lively and achieved exercise targets extra typically than these utilizing exercise trackers with out the sport. The examine lasted solely 12 weeks and enhancements waned considerably after it ended, so the long-term influence of such a program is unsure.

Bodily exercise trackers have rapidly turn out to be a multimillion-dollar product class. I don’t see them going away any time quickly. However, to really get folks transferring and have a constructive influence on well being, we’ll most likely want to make use of them in additional modern methods. And in the event that they declare to enhance your well being, we’ll want high-quality analysis to again that up.
