How Does a Fitbit Work?
To sense movements of the user, a Fitbit Tracker uses an accelerometer, which is three-dimensional technology similar to Wii gaming remote controls. The Tracker measures the steps you take, combining that information with user data to calculate distance walked, calories burned, floors climbed, activity duration, and activity intensity. Using OLED display, the Tracker also measures sleep quality by recording periods of restlessness, how long it takes the wearer to fall asleep, and your length of time asleep.
A wireless base station is included in your Fitbit purchase to receive data from the Tracker and also charge the battery. When you connect the Tracker to a computer, the base station will upload data to the Fitbit website. Free for you to use, the website allows you to see an overview of your physical activity, setting and tracking goals, keeping food and activity logs and interacting with friends. You can do of this on your mobile apps. as well.
The battery for most Fitbits lasts 5–7 days, and it can take 1–2 hours to charge. You may need to charge your Fitbit on at least one night during your vacation.
Are Fitbits Accurate?
Many studies have been completed to determine how accurate Fitbits are. Iowa State University‘s tests determined the bands were at best “reasonably accurate,” with the Fitbit Zip and Fitbit One scoring 10.1% and 10.4% error ratings. The Center for Behavioral Cardiovascular Health at Columbia University Medical Center tested the accuracy and reliability of Fitbit devices, including the Fitbit One and Fitbit Flex. Their test results showed that, overall, Fitbit devices worn on the hip accurately measured steps taken within 1 step of 100% accuracy. Devices worn on the wrist, however, were off by an average of 11 steps per minute. When measuring the number of calories burned Fitbit devices worn on the hip underestimated by an average of 6%, while devices worn on the wrist overestimated calories burned by 21%. Authors concluded that both the Fitbit One and Fitbit Flex devices reliably measured step counts and energy expenditure, with hip-based Fitbit devices being more accurate than wrist-based devices.
Back in 2012, Fitbit released a “Wi-Fi smart scale” called the Fitbit Aria. It recognizes users who are wearing Fitbit trackers and measures weight, BMI = body mass index, and percentage of body fat of the user. The scale can keep track of up to eight individual users and will update information to fitbit.com automatically using Wi-Fi networks. The information is also updated to the mobile apps. So you could return from your trip, and your Fitbit compatible scale will already know the results of your vacation.
