An activity tracker, also known as a fitness tracker, is a device or application for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep. It is a type of wearable computer. The term is now primarily used for smartwatches that are synced, in many cases wirelessly, to a computer or smartphone for long-term data tracking. There are also independent mobile and Facebook apps. Some evidence has found that the use of these type of devices results in less weight loss rather than more.
The term “activity trackers” now primarily refers to wearable devices that monitor and record a person’s fitness activity. The concept grew out of written logs that led to spreadsheet-style computer logs in which entries were made manually, such as that provided in the US by the President’s Council on Physical Fitness and Sports as part of The President’s Challenge. Improvements in technology in the late 20th and early 21st century allow automating the monitoring and recording of fitness activities and integrating them into more easily worn equipment. Early examples include wristwatch-sized bicycle computers that monitored speed, duration, distance, etc., available at least by the early 1990s. Wearable heart rate monitors for athletes were available in 1981. Wearable fitness tracking devices, including wireless heart rate monitoring that integrated with commercial-grade fitness equipment found in gyms, were available in consumer-grade electronics by at least the early 2000s.
In those who are overweight or obese some evidence has found that the use of these type of devices results in less weight loss rather than more after 18 months of use. However, it has been noted that the activity tracker used in this study is a now discontinued tracker that is worn on the upper arm which might be uncomfortable, and wear times of the tracker were low.
Another study comparing 8-week interventions and four month follow-up of physical activity monitors, a guided weight loss program, and both together found that activity monitoring and the weight loss program were associated with similar improvements and both combined together were associated with more improvements than either alone. It is unclear if these devices affect the amount of physical activity children engage in.
