I wear both a FitBit and Shine Health Tracking Device on my wristOn Sunday night I left the house for a quick run. It was 9:20pm. It’s been years since I ran in the dark and likely a decade or more since running at night made any sense in my life. As every parent knows, we’re jailed in our houses around 8pm when the kids go to bed — if exercise hadn’t yet happened it gets pushed off until “tomorrow.”

Sunday night the Fitbit was 100% of the driving force behind me putting on my running shoes. I was about 500 steps shy of my 10,000 step goal and couldn’t go to bed, in good faith, that close to success (see image below).

Crazy or perfect? I wear 2 devices now. This month I added a Fitbit to my wrist; I’d already been wearing my Shine for a year or so and had certainly had seem improvements in self-awareness, a better understanding of my sedentary days at work, and the rewards of having daily data about my movement. I exercise a lot more now compared with a year ago. The reasons are multi-factoral of course (turning 40, losing loved ones, craving exercise) but the device has unequivocally helped. Adding the Fitbit to my wrist was designed to help hone an understanding for the level of consistency 2 devices can have (on the same person). The other reason was Fitbit would allow me to “compete” and/or compare daily totals with my husband. This is 40, my friends.

before and after runNo question that in short order the Fitbit has helped me understand the difference between my movement and my activity, something I’d not really spent time on previously. For example, Sunday was a day of housekeeping. I’d moved around all day doing errands, going to store to buy hangers, cleaning the closet, goofing around with the boys, but I hadn’t been out for a run or bike ride — my first glance my Fitbit was about to give me a false sense of security. I nearly got my goal (in steps) without any real, active “exercise.” Like almost 1/2 of American adults, I hadn’t gotten the 30-60 minutes of moderate-to-vigorous activity (walking briskly, running, cycling, swimming) we all crave and need. All the sudden it dawned on me — it wasn’t just the number of steps I’d had on Sunday that mattered it truly had to be about how I got them. I was 500 steps shy of my goal of 10,000 steps but the Fitbit also told me I’d only had 2 minutes, the whole day, of active time. YIPES!

I headed out into the beautiful summer night,  a quick loop in the neighborhood and I’d achieved my distance/step goals (the device buzzed on my arm when I reached 5 miles), but I felt so good at that point I went around again and tacked on another mile or so. And poof — there I was with 30 minutes of active time.

These devices are changing my life, and hopefully my health.

HERE’S the rub. My anecdote is just that. I’m one person, one personality (goal-oriented), with two devices. To know if these devices are really worth their weight (and cost) for all sorts of people we need to study them fastidiously. Activity trackers are creating all sorts of data and we need to know what to do with it, in and out of the health care system.  That’s, thankfully, where research comes in. Check out this quick blog post from Dr Jason Mendoza here at Children’s. He’s beginning to look at how activity trackers may influence teens activity (and health). Let’s capture more data so we can all get moving more, faster. It’s obvious to me that if we start with children we certainly will be primed for success in profound ways as middle age, and the “this is 40″ period of life sets in.

Two big questions:

1. Do these snazzy gadgets work to improve teens’ physical activity?

2. How can we make them work even better?

In order to help answer these questions, researchers at the Seattle Children’s Research Institute are currently conducting a study involving the Fitbit Flex. Teenage participants, ages 14-18 years, in the Seattle area are enrolling in the study to help answer whether or not the Fitbit device helps teens stay active.
