Types of heart rate monitors, benefits and advantages


Types of heart rate monitors
A standard heart rate monitor is a device that monitors heartbeats and saves or transmits data to another device. Almost every model is equipped with a monitor that displays your heart rate in real time.

Purchase heart rate monitors:

  • people with diseases of the cardiovascular system;
  • amateur athletes who need to understand the level of maximum permissible loads;
  • professional athletes monitor their heart function during competitions and preparation for them.

The device sensor can have 2 placement options:

  • external;
  • integration into the body.

Devices from the first group read heartbeat indicators and transmit them to other devices. The signal can be:

  • analog – information is redirected to a gadget or exercise machine, but the sensor is able to catch data from other people’s heart rate monitors and get lost in areas of increased electromagnetic activity;
  • digital - the sensor is not capable of transmitting data to other devices, but independently processes it and stores it in memory.

Based on the type of attachment to the body, devices are divided into 3 groups:

  1. Carpals . They must fit tightly to the skin, since the pulse is measured by transilluminating the skin and marking the level of vasoconstriction. The model is simple and convenient, but is known to distort the result due to increased sweating at the measurement site during physical activity.
  2. Chest . Recognized as the most reliable and accurate in the segment. They are attached at chest level with a special tape and can be hidden under clothing. The heart rate monitor transmits the received data to a smart watch or smartphone. The chest device is relevant for almost all types of loads.
  3. Headphones . The most compact and convenient option of all. The heart rate monitor looks like a small clip and is attached to the earlobe. During sports it is imperceptible, but after wearing it for 5-6 hours it can put pressure on the ear and cause discomfort.

Important! The heart rate monitor provides a large amount of data that everyone can use to improve their performance.

How to choose a good heart rate monitor


A good heart rate monitor
How to choose the most suitable heart rate monitor and what to look for? Experts recommend focusing on the purpose of the device:

  • multifunctional models that are above the average level are suitable for professionals;
  • For fans, standard devices with a basic set of options are enough.

In addition to the above, do not forget about a set of basic criteria. Taking them into account, you will select the most suitable model.

Heart Rate Zones

The term “pulse zone” refers to the heart rate required to achieve a certain result. Knowing the exact indicators of your pulse, it is easy to determine the load and stick to it.

The load levels correspond to the following heart rhythms:

  • warm-up, physical exercise for recovery - up to 60% of heart rate;
  • beginner athletes, people with various diseases – up to 70%;
  • load for developing endurance and fat burning – up to 80%;
  • building muscle mass – up to 90%;
  • the maximum limit is up to 100%.

Advantages and disadvantages

constant monitoring of heart contractions

ability to stay within the required load

clear understanding of the number of calories burned

progress tracking

overload protection

Basic functions of the heart rate monitor

The functionality of the heart rate monitor is divided into 2 groups:

  • basic;
  • additional.

Basic characteristics include:

  • heart rate analysis;
  • selection of load level;
  • indication of exit from the selected training zone;
  • the ability to set average and maximum heart rate values;
  • timer;
  • stopwatch;
  • calculating calories burned;
  • setting date and time.

The list of additional options is quite wide:

  • pedometer;
  • navigation;
  • history of all training;
  • setting records (weekly, monthly, etc.);
  • synchronization with different types of devices and more.

Important! Even a few additional functions will raise the cost of the heart rate monitor several times. Therefore, before purchasing, be sure to assess your current needs.

How accurately does the device work?

The accuracy of the device depends on its quality, but, as a rule, these devices give correct readings. The error is no more than 2-3%. The figures closest to real values ​​are given by devices with a remote coupling.

This is, for example, the PM-60 Mindray, which senses saturation from 0 to 100%, suitable for measuring indicators in infants and adults. But the cost of the device is from 32 thousand rubles, so it is not practical to buy it for home. Such pulse oximeters will be useful in hospital intensive care units. Of the above devices, NELLCOR Oximax has a remote coupling.

You should not try to buy the most expensive pulse oximeter possible to monitor your health. After all, information about the volume of oxygen in the blood and heart rate alone is not enough for assessment. Pulse oximetry data should be considered in conjunction with others: temperature, general health, etc.

The following may prevent the device from taking correct readings:

  • Incorrect use of it. For example, when a finger is not fully inserted into a niche, or they actively move during measurement.
  • Nail polish. The presence of gel polish is especially undesirable, since a thick layer affects the sensitivity of the device.

    Which watch to choose with blood pressure measurement: all the nuances and the best models

What is the difference between a heart rate monitor and a smart bracelet?

A heart rate monitor is a highly specialized device whose purpose is to measure heart rhythms. Whereas smart watches for sports have a wider range of applications. Even models with an integrated heart rate monitor provide greater error than a conventional heart rate monitor.

Therefore, to accurately determine your heartbeat, choose a heart rate monitor. And if you need a gadget with a long list of capabilities, buy a smart bracelet.

A heart rate monitor is one of the most popular devices in the sports industry. With the right choice, it will be a reliable assistant on the path to improving your results and developing endurance.

Smarterra O2

Among the top devices recommended for purchase is the Smarterra O2 model, which can be purchased for about 2,000 rubles. Easy to use and compact, the device weighs only 29 g and displays data on the screen 20 seconds after the start of measurement. Measurement accuracy is 2%, at the level of professional equipment. The display is large and bright, suitable even for elderly patients with low vision and for use in low light conditions.

Among the advantages of the gadget are high speed, reasonable price and small size. However, as user reviews show, the actual level of accuracy is inferior to professional equipment, and the build quality is not very high.
