Taking the stairs instead of the elevator, walk as often as possible, to make a jog from time to time... If daily life reserve on multiple occasions to maintain its physical form, it should be a good dose of will to keep to its resolutions of year end. With his watch FA20, Polar has just thought of the non-sportifs who want to limit the unnecessary kg and prevent cardiovascular problems. It resembles a real watch, look it is true enough sports, but that can be worn on a daily basis the model is also available in white. But inside hides a cookie that monitors the physical activity of its owner 24 hours a day. And this without having to push a single button. At the end of the day is know therefore whether the exercise of the day has been beneficial. The user can also choose to program the device to an exercise in particular walking or running. This is the tip of this device is not a heart rate monitor, the great speciality of Polar. Precise and practical training, the heart rate monitor requires to wear a belt around the chest to save his heart. Little compatible, therefore, with daily life.
Sensors piezzoélectriques

The FA20 simply calculate the number of steps and distance travelled, without even having to indicate average length of its progeny or its not, as with some pedometers. In a field test, the watch yet provided a fairly accurate distance. The explanation is the presence of sensors piezzoélectriques record the intensity of the shock of the foot on the ground and deduce the length of the step, and therefore the distance. Knowing the gender, age, size and weight of the user, the FA20 uses a known sports Physiology specialists equation to calculate the number of calories burned during exercise or the day. The accuracy is low, the order of 20, but can get off at 10 for the average user, for example a man of 70 kilograms. The FA20 is really useful and can encourage them to exercise, so it retains data for nine weeks. For Véronique Billat Professor and Director of the Integrative Biology of adaptations to exercise depends on the Inserm and the Genopôle of Evry, it is a useful object: "We advocate to at least 7,000 not by day." Must be able to measure them. With this type of product it becomes possible, without having to wear something other than a watch. Then infer the energy expenditure is calculated fairly simply. It considered that an individual spends about 0.5 calorie per kilometre and per kilogram. In the end it is therefore a good tool for motivation.
Connection to a PC
Little criticism, a lack of readability under some lighting. Cheap, it can also connect through a PC to the Polarpersonaltrainer Web site. Which allows to view its personal data on a much longer period and to benefit from a little custom training programs. It should be investing EUR 50 additional connection system. Last disadvantage, the most boring, the technology used in the FA20 knows not (yet) to measure the efforts made by a cyclist or a swimmer. Two sports yet excellent fitness regardless of age. Polar should think.
