How to choose a fitness bracelet?

A healthy lifestyle is not only proper nutrition, walks in the fresh air and physical activity. This concept also includes monitoring the main health indicators. Previously, to diagnose the body, you had to go to a clinic, but with the advent of modern devices, many parameters can be determined independently.


What is a fitness bracelet?

One of these devices is called a fitness bracelet or fitness tracker. It is designed to track physical activity and is produced by many manufacturers, both well-known global brands and more modest companies.


The fitness bracelet is fixed on the hand according to the same principle as a watch. Initially, such a gadget was used by professional athletes, but later it became available to everyone. The device tracks the main biological indicators in real time, both during physical activity and at any other time.


Device functions

Fitness tracker models differ in the set of functions, which depends on the built-in sensors. Thus, an accelerometer is used to count steps and determine the speed of movement - a mechanism with a counterweight that responds to the movement of the body in space. A gyroscope is used to evaluate a person's movements in three-dimensional format, and a GPS sensor is used for more accurate calculations.

There are fitness bracelets with a pressure and pulse sensor - an LED device whose operating principle is based on the different reflection of light by the blood flow in different phases of cardiac pulsations. The device analyzes the pulse rate, pulse wave speed and calculates approximate blood pressure indicators taking into account age, weight and other physiological parameters. The functions of fitness bracelets are quite diverse, and among them there are many useful options.
