Do I need to buy a pedometer?
An active lifestyle is the key to good health and well-being. But not everyone complies with the doctors' recommendations and devotes time to physical activity. And how to measure such activity and understand in which direction to move? A special device - a pedometer - will help in this.
What is it and why?
A pedometer is a device that measures the number of steps taken over a certain period of time. What is this device for? To assess your physical activity, which is sometimes necessary. For example, walking is recommended for some diseases of the musculoskeletal system, as well as the respiratory and cardiovascular systems.
But such an exercise will be useful only if a certain number of steps are taken. And the pedometer will help to measure it. But do not think that he will actively contribute to losing weight or improving health. Yes, it is a good helper and a great incentive to improve discipline and increase concentration, but no more.
How to make a choice?
How to choose a pedometer? When you purchase you need to consider a few important points.
Principle of operation
If the classification principle is based on the principle of operation of the device, then the following types can be distinguished:
- Mechanical pedometers appeared the whole two centuries ago and were the very first. The principle of their work is quite simple. The device has a weight fixed on a spring and swinging like a pendulum. At each step, this load moves and moves the gear gear by one tooth. She, in turn, provokes the movement of the arrow on the dial one division. In the end, after a walk on the dial, the number of steps taken will be reflected. Such devices are almost a thing of the past and are rarely found in stores today.
- The electromechanical pedometer has a built-in mechanical sensor that picks up all the vibrations of the body and converts them into electrical impulses sent to the microprocessor and reflected on the display in digital form. This type can be called the most reliable, but since the sensor can respond not only to the steps, but also to other movements of the human body, errors are likely to occur during the calculations.
- The electronic view of pedometers is considered the most difficult, since complex programs involving multi-level mathematical calculations are used to calculate steps. The results will be accurate, but if the program fails, the device will fail. And it's not so easy to fix it.
Modern models have built-in accelerometers with two (2D) or three axes (3D). 3D sensors allow not only to record movements, but also to evaluate them. And the microprocessor, for example, will not respond to activity that is not related to walking (for example, waving your arms or changing your body position).
In addition, there are pedometers with two sensors that are the most accurate. If one sensor will produce reliable results only with ideally correct fastening, then two will allow to exclude errors at any location.
Features of use and method of attachment
According to the method of attachment there are the following types of pedometers:
- A pocket pedometer can be placed, for example, in a pocket or bag. It is quite convenient, because the device will remain invisible to all others. But then it will respond not only to the steps, but also to any movements, for example, to squats and to any other changes in the position of the body.
- Some pedometers are attached to shoes, for example, to laces. This is quite convenient, since the device will consider the movements of the legs, that is, the steps, and not the waving of the arms, like some other models.
- Some pedometers have a sensor that is fixed directly on the sole and is triggered by each touch of the support by pressing a button. This is not very convenient and may cause discomfort while walking. In addition, with active use, the device can quickly fail.
- The pedometer bracelet is a device that is worn on the wrist. It is easy to use, and it looks like a low-key accessory. When choosing it is worth paying special attention to the strap, as it will constantly contact the skin and in case of poor material quality can cause allergy. The best option is a leather strap. But silicone is becoming increasingly popular. They are well stretched, durable, strong, comfortable to wear, and also completely hypoallergenic.
- A pedometer with a strap is usually attached to the arm, and not only on the wrist, as the previous view, but also on the forearm or shoulder. For some, it is more convenient.
- The pedometer-clip is attached to the waist, and this is not always possible or convenient. Of course, you can put it in your pocket or bag, but this placement will greatly reduce the accuracy of calculations. In order for the results to be reliable, it is desirable to secure the device in line with the front of the thigh.
- More and more popular are pedometers-programs. Such an application can be on the phone or other similar device, which is very convenient. But the accuracy of calculations leaves much to be desired.
Modern models may have a whole range of additional functions:
- A pedometer with a heart rate monitor not only measures the number of steps, but also allows you to monitor the pulse.
- Memory. The device can store the results and store them, which is sometimes very useful and even necessary.
- Calculating calories burned. This function will especially please the girls, but you shouldn’t be deceived, because burning calories will depend not only on the number of steps, but also on their quality, as well as on the speed of movement.
- A pedometer with a clock will allow you to follow the time without stopping from walking.
- GPS Such a function will help draw up the route of the walk and correct it while driving.
- The ability to connect to a computer will be required if you are serious about your health and build charts or create tables.
- Protection against vibrations will increase the reliability of the results during walks on sloping or hilly terrain.
- Measurement of distance traveled.
- A timer is required when walking or running for a while.
- Built-in thermometer and even a barometer that measures atmospheric pressure.
The price of the pedometer will depend on the manufacturer, type and set of additional functions. So, the most simple Chinese models can cost about 500-1000 rubles. The cost of higher-quality and complex models can vary from 1.5 to 3 thousand. And modern and sophisticated pedometers can cost about 5-7 thousand.
