Heart rate monitors and pedometers: types, advantages and disadvantages, how to choose, Environmental Specifications

Pedometers, heart rate monitors, pulse oximeters, Cardiosensor, sports and tactical watches are used to maintain health and beauty. Sometimes these devices are combined into a single multi-purpose device.

Principle of operation

Pedometer

Mechanical pedometer is characterized by a simple device:

• Spring loaded with swinging like a pendulum.
• Each leg movement moves one gear tooth, hand shift dial with the number of steps shown.

Popularity of these products do not enjoy.

Electronic-mechanical pedometer transfers heat to the body vibrations at each step. The information goes to the transducer which converts the heat into an electric pulse. The result is displayed on the screen.

The electronic pedometer counts steps by using a complex mathematical formula. Some models use a connection with the satellite.

pulsometer

The device helps to determine the optimal training regime. Purpose - To measure heart rate, ie pulse. The principle of operation resembles the action of an ECG:

• First, there are the electronic signals from the heart muscle.
• They catch the sensor.
• Next, pulses supplied to the receiving apparatus, wherein the information is processed.
• Then, the results appear on the display.
