Due to the margin for error in the data analysis, fitness trackers can provide tentative data which should not be considered the absolute last word.The U.S. There is likely some inaccuracy at this stage as most mass produced gadgets will not be tailor made to the individual’s needs. The raw data collected by the sensors is converted into activities by computer algorithms. They may be able to tell the difference between a gentle stroll and a fast jog, but expecting them to record all the parameters accurately all the time is unrealistic. Two fitness trackers from the same company may provide slightly different results for the same individual because the sensors they use will record the data just a bit differently. Since the data obtained from the gadgets is highly dependent on the sensors, there are a number of things which may go wrong. Those suffering from sleep disorders and need to be monitored all night can use fitness trackers instead of spending each night at the sleep lab.Diabetics who have been advised to keep track of physical activity as well as the number of calories they consume every day.Athletes looking to track their body’s parameters during extreme training sessions.Patients suffering from high or low blood pressure can use them to get continuous data on their heart rate.Some people who should consider getting a fitness tracker include. The affordable and easy to use gadgets are very popular and can be put to good use for a number of purposes. These days the personal fitness tracker is more of a fashion statement than a medical necessity. They can, however, be reprogrammed for another person when the individual is done using it for good. This is why most fitness trackers need to be personalized and cannot be shared by people. The first time a person calibrates the gadget, they will have to add their personal data such as weight, height, age for the algorithm to function properly. Here the data collected by the physical sensors are put through an algorithm to make sense of the movements of a person. In most cases this software can be synchronized with a smartphone or a computer. The software is what allows the data to be collected and analyzed from the physical gadget. The physical gadget is usually worn on the wrist and may have a replaceable or rechargeable battery. Most fitness trackers will consist of two parts – the hardware and the software. This method of tracking body movements to measure sleep is known as actigraphy. The more movement at night, the less restful the sleep would have been. However when the data is computed the next morning, it will analyze the movements to let the individual know how peaceful their sleep had been. When the fitness tracker is set to ‘sleep mode,’ the device still records movement data. The same sensor which detects steps using an individual’s motion is used to detect sleep quality.
