Activity trackers: What's all the fuss about these small yet significant devices? by Carol Kennedy-Armbruster, PhD

Millions of people of all ages are reaching for activity trackers (ATs) to help them increase their activity levels. These trackers, examples of wearable technology, are offered in a variety of forms and styles by companies such as Fitbit and Garmin, but all are designed to encourage wearers to move more and sit less. Recent research indicates that ATs may help users increase their physical activity levels through a combination of information, physical cues and behavioral techniques such as goal-setting, social support and motivational rewards.
