Watch for athletes with heart rate monitor. Sports watch with heart rate monitor

The life of a modern person cannot be imagined without various technological devices. One of these is smart watches. The market is constantly replenished with new models, among which there are those created for active people who follow not only fashion trends, but also their health; these are watches with a pedometer, which, among other functions, allow you to monitor physical activity and the state of the body.

About sports watches

Smart watches with the functionality of measuring the number of steps, heart rate, and blood pressure are often called sports watches, since the original idea of ​​​​such devices was to monitor the state of the body during training and various types of physical activity.

Sports smart watches for active people

Of course, before them there were devices with which various indicators were measured. However, among other advantages, a watch with a pedometer and a built-in heart rate monitor boasts convenience. With them, there is no need to carry additional devices that distract you from playing sports.

In addition to athletes, such watches will be useful for people suffering from diseases of the cardiovascular system.

Types of sports watches

The choice of a particular model is influenced by several factors, including the external design and functionality of the device, the latter largely determining the cost of the watch.

It is by appearance and characteristics that the following varieties can be distinguished:

  1. Fitness trackers - a bracelet-style device is the simplest among all smart watches for sports. The name itself suggests that such a device should be chosen by those who plan to use it exclusively for amateur fitness classes and strive to control their activity.

Variety of fitness bracelets

  1. – the device received this name because it was originally designed with this very function. Today, in addition to its main purpose, a gadget often has a built-in GPS, is equipped with a navigator, makes it possible to receive notifications about calls and messages, and can also be used as a trainer. All that is needed for such a device is synchronization with a PC
  2. Smart watches are the most functionally equipped devices, which, on the other hand, have a noticeable drawback - the constant need to synchronize with a smartphone.

Separately, it can be distinguished with a built-in pedometer, which is distinguished by its bright design and ease of use.

Sports watch with heart rate monitor

A sedentary lifestyle and lack of physical activity increase the likelihood of cardiovascular disease. However, excessive physical activity can be no less detrimental to the heart. This primarily applies to children, disabled people and elderly people. Sports training will only be beneficial when its duration and intensity are balanced. A sports watch with a heart rate monitor will be of great help with this.

The heart rate monitor was created to monitor and track your heart rate (HR) during sports. This device first appeared in 1977 in Finland. It was developed for the Finnish ski team by doctor Martti Karvonen. Their mass production began in 1983. At first, heart rate monitors were chest-mounted, but recently their wrist-mounted version has become increasingly popular, and this is not surprising. It is much more convenient to wear the device on your arm than on your chest. True, the sensors are often still attached to the chest (sometimes on the earlobe or to the finger, but this is not always convenient, and the accuracy of the readings is reduced).

A heart rate monitor bracelet for sports has two main elements: a chest or built-in sensor and a receiver on the wrist, a GPS navigator or a mobile phone. This device is used by people involved in a variety of sports. A heart rate monitor with a running watch is a good choice for track and field athletes. For swimmers, a waterproof swimming heart rate monitor would be best. Skiers, tennis players, cyclists, and fitness athletes will also be able to choose the right model for themselves. Sports watches with a pedometer are also widely used, which can be used not only for training, but also for daily walks or hiking.

Monitors for measuring and monitoring heart rate are especially necessary for those involved in sports who have various health problems: people with cardiovascular diseases, diabetes, overweight or kidney failure.

Functions of modern smart watches:

  • regular watches;
  • heart rate monitor (pulse measurement);
  • tonometer (measures blood pressure);
  • sound notification about body overload;
  • setting the desired training pace and calculating the time for rest;
  • alarm;
  • determination of average and maximum heart rate;
  • stopwatch;
  • pedometer;
  • store reports of the latest training sessions.

Good quality multifunctional heart rate monitors are produced by Beurer, Garmin and Polar. Their models are equipped with shockproof and moisture-resistant coating, which also protects the display from scratches. Particularly noteworthy is the Beurer brand, which has been producing health and beauty products for almost 100 years. This company is constantly expanding its range of products that are made of high quality materials and are easy to use.

What to look for when choosing a heart rate monitor

  • Protection from external influences (mechanical damage and moisture).
  • Operating time of the device without recharging. It must be remembered that the more applications a device has, the faster energy will be consumed for its operation.
  • Accuracy and reliability of data. The duration and intensity of training depends on them.
  • Appearance of the device. In principle, it can be anything, but it is better that it is in harmony with the rest of the sports equipment.

Our specialized online store offers you to select and buy watches with a heart rate monitor. The price primarily depends on the number of applications, as well as the quality of the materials used.

Leading a healthy lifestyle is a plan for every Monday and a promise that millions make to themselves before going to bed on Sunday. And in the morning, after the first one, with muscle pain, lethargy and apathetic fatigue, this decision takes the opposite turn. There is nothing good in this way of life and there is neither desire nor need to lead it when it is so painful and unpleasant.

But the whole point is in the incorrect organization of sports training. Selecting the intensity of the load and setting the right pace so that the activity brings not only benefit, but also pleasure - tasks that must be approached with the utmost seriousness. In a world where digital technologies are deeply rooted in every sphere, sports are no exception. We bring to your attention a review of men's and women's sports watches with a heart rate monitor, stopwatch, blood pressure monitor and pedometer.

What are sports accessories for?

During training, it is impossible to objectively assess the state of the body.. Fatigue, increased heart rate and, as a result, problems with blood pressure and general fatigue cause health problems. In this regard, it is recommended to play sports using special devices that are designed to monitor the state of the body during training.

Sports watches - a new product in the world of gadgets - perform all these functions. A heart rate monitor, pedometer and blood pressure monitor, which are built into such an accessory, effectively and accurately track all vital signs and inform its owner about it. Such a device allows you to:

  1. Set the right workout pace;
  2. Determine the optimal time for rest and its intervals;
  3. Calculate the duration of rest, which will completely restore strength.

The use of a heart rate monitor is to determine the level of vibrations in the walls of blood vessels, which is individual for each person.

It is he who determines the moment when it is better to stop all physical activity.

The pedometer helps to track and control the amount of distance traveled and create an individual load schedule, gradually increasing the mileage.

It is a confirmed fact that Every day to maintain vigor and health you need to take 11,000 steps. If the goal is to lose excess weight, then this figure should be increased to 13,000 - 16,000 per day.

And finally, a tonometer is a device for measuring blood pressure.

The sensor in the watch will measure the pressure in the largest artery in the body - the aorta, which is located closest to the heart and brain. In case of excessive physical activity, this indicator determines the critical point when the activity should be stopped urgently in order to prevent the occurrence of a stroke or heart attack.

Criteria for choosing a sports watch

The range of sports accessories is so large that it is extremely difficult to decide on a device that will suit each individual lifestyle. When choosing a sports watch, consider the following features:

  1. Operating time - the more functions they perform, the more energy they spend, which means they require frequent and long-term recharging;
  2. Synchronization - the ability to connect to mobile platforms and operating systems;
  3. The notification method is a sound signal that warns of the approaching critical point. It is better if the watch is equipped with a notification via vibration;
  4. Accuracy of displayed data;
  5. Waterproof;
  6. Impact resistance;
  7. Design.

The functionality of sports watches is not limited to devices that measure steps, pulse and blood pressure. If you wish, you can purchase a watch that will record your workout history, keep track of calories burned, determine your “fat burning zone,” as well as conduct a fitness test and determine your own training program based on your level of physical fitness. It is worth remembering that a watch is only a mechanism, and the indicators it produces are purely mathematical calculations based on numerical data.

Sports watch manufacturers

Among the huge number of manufacturers, the following have earned a reputation for quality and functionality:

    Polar is a Finnish manufacturer that has been on the market for 30 years. The watches of this company are distinguished by their relatively high cost and wide range of functions. The initial cost of such watches is 130 USD.

    Casio- versatility and innovation are the distinctive qualities of the brand's watches. It was this company that pioneered the production of sports watches with a pedometer. The cost varies from 100 USD. up to 450 USD

    Вeurer- German manufacturer of sports watches. Depending on your financial capabilities, you can purchase both the budget version PM18, which costs about 100 USD, and the more expensive and functional PM200, the price of which is 500 USD.

    Suunto is a Finnish manufacturer whose sports watches are distinguished by their versatility and quality. One of the most expensive in its segment and the purchase will cost 200 USD.

    Torneo is a Chinese company that produces very high-quality sports products at an affordable price. Sports watches with a basic set of functions are priced at 125 USD.

Video review of Suunto sports watches:

The choice of a sports watch with a heart rate monitor, pedometer and blood pressure monitor should be based on the range of additional functionality. After all, sometimes basic functions are enough, and frills will only increase the cost without adding an ounce of usefulness.

Basic rules of use

In order for a sports watch to correctly display the necessary data, you must adhere to the rules and operating instructions. Individual recommendations have been developed for each model, but there are also common ones for all.

Blood pressure is calculated by the sensor based on a baseline value that is entered manually. This data must be regularly updated and entered with special care, because this will reduce the error of readings to a minimum.

Basic indicators are those that include data at rest and after physical activity. Please note that you need to perform the exercises that are listed in the instructions. When setting up a pedometer, the necessary parameters will be the average step length, body weight and age.

The principle of operation of a sports watch is to supply impulses through the back cover, so it is important that it fits snugly.

The hand must be left, only in this case you can expect reliable data.

Of course, you shouldn't expect a sports watch to perform magic when you put it in your pocket or wear it over a thick sleeve.
