![]() ![]() Intense exercises are not a necessity for weight loss or burning calories. What do the experts suggest to us?Įxperts suggest that adults should be getting at least 150 minutes per week of physical exercise. The results varied widely but the Fitbit showed the best results in terms of accuracy and validity, in comparison to Garmin.įitbit and other wearables provide a way to track the number of calories burned through physical activity by combing various health data.Įven though technology may have its flaws, the Fitbit calorie estimate is an overall helpful tool in determining the next steps to a healthy lifestyle. Participants over the age of 65 participated in a study comparing Fitbit Charge 2 and Garmin vivosmart HR+. The study concluded that Fitbit overall does have moderate validity and reliability for measuring physical activities. Activity energy expenditure from Fitbit was 808.1 calories while the Actigraph was 538.6 calories. Individuals wore both these devices while performing activities such as incline walking, running, and stepping. One study compared the accuracy of Fitbit Flex and Actigraph GT3X+. ![]() How does Fitbit track calories burned?įitbit devices integrate measurements of basal metabolic rate and breathing, heart rate, and other daily physical activity data to accurately measure the number of calories burned.īasal metabolic rate is calculated by manually logging data into the app such as sex, age, height, and weight. This feature is especially useful when determining the intensity of a workout or exercise. ![]() Heart rate is measured by another sensor in the Fitbit that responds to volumetric changes in the capillaries of the wrist. Fitbit does not count steps from walking down a flight of stairs or exercising on the “StairMaster.”Ĭapillaries expand and contract when the heart beats. Step count is measured by a sensor that responds to elevation (1 floor = 10 feet). The device uses algorithms to measure step count, heart rate, calories burned, basal metabolic rate, and sleep. Why? In comparison to other places on the body, the wrist serves both comfort and user-friendliness.įitbit devices are wrist-worn technologies that use a triaxial accelerometer to measure body motion in 3D space. Most fitness tracking devices are worn on the wrist. How does the fitness tracking technology work? Physical activity encourages daily calorie burn.Įating healthy and staying active can help individuals with obesity lose weight and maintain a healthy body weight. These averages vary depending on age, weight, and height. Whereas men require 500 more calories to lose 1 pound per week. What factors can influence daily caloric needs?įactors such as gender, age, weight, and height can affect daily caloric intake needs.įor example, women on average should limit themselves to 1500 calories to lose 1 pound per week. In addition to helping maintain a healthy weight, studies show that restricting calorie intake can reduce the risk of Alzheimer’s disease, oxidative stress, and cancer. Obesity is a growing problem, particularly in Western societies, increasing the risk of chronic disease. The intake of excessive amounts of calories may lead to obesity. The intake of calories from food nourishes the body’s cells with the energy required to perform daily tasks such as thinking, walking, and talking. When food begins to break down, it releases this energy which may be used immediately or stored for later. What are calories and why do they matter?Ĭalories are essential for the metabolism of the basic functional macromolecules. sells a variety of different products including fitness trackers, smart scales, and smartwatches.įitness super watches like the Fitbit Surge, have an integrated GPS, a touchscreen monitor, and wireless syncing. The company, “ Fitbit Inc” from California, USA holds 20% of the market share value for wearable tracking technologies. Monitoring individual physical activity is an effective and important method to promote a healthy lifestyle.įitbit tracking devices measure both physical activity and health statistics, such as oxygen saturation, step count, heart rate, and calories burned.įitness trackers have become increasingly popular as both, science and technology, continue to evolve in the 21st century. ![]()
