The guide to choosing the best heart rate monitor.

Heart rate monitors for cycling are electronic devices designed to measure a cyclist's heart rate during training or competition. These tools are very useful for monitoring the intensity of physical exertion, optimizing training, and improving overall performance.

The heart rate monitor measures heart rate, that is, the number of heartbeats per minute. This device is capable of detecting and recording the cyclist's heartbeat through optical sensors or electrodes placed on the wrist, chest, or other parts of the body.

Heart rate is an important indicator of exercise intensity during training or competition. By monitoring heart rate, the heart rate monitor provides useful information to assess the level of effort, monitor training effectiveness, and adjust intensity to optimize performance.

Some heart rate monitors may offer additional functionalities, such as monitoring heart rate variability (HRV), which provides information on the body's adaptation to stress and fatigue. Some advanced models can also measure the power produced by the cyclist, the cadence of the pedals, speed, distance traveled, and other related metrics.

It is important to note that heart rate monitors provide an estimate of heart rate and can be influenced by various factors, such as temperature effects, sensor positioning, and proper adherence. Therefore, it is advisable to use the heart rate monitor as a reference tool for assessing exercise intensity, but not as a precise medical measurement.

Heart rate monitors work by using sensors to measure the cyclist's heart rate. There are primarily two types of sensors used in heart rate monitors:

Optical sensors: these sensors use optical detection technology to measure heart rate through contact with the skin. They are usually positioned on the wrist and use a combination of LED lights and photodiodes to detect changes in blood flow caused by heartbeats. These sensors are convenient and easy to use, as they do not require the use of chest straps or other external devices.

Chest straps: the chest strap uses electrodes that are positioned around the cyclist's chest, usually under the breast. These electrodes detect the electrical impulses generated by the heart and transmit them to the heart rate monitor. Chest straps are considered more accurate than optical sensors but require a snug garment for proper placement.

Regardless of the type of sensor used, once the heart rate is detected, the heart rate monitor processes the data and displays the result on the device's screen. In many models, it is possible to set custom heart rate limits and receive alerts when certain values are exceeded.

Some heart rate monitors are equipped with wireless functionality that allows connection to external devices such as sports watches, bike computers, or smartphones via Bluetooth or ANT+. This enables the display and recording of heart rate along with other metrics like speed, distance traveled, and power, providing a more comprehensive analysis of performance during training or racing.

In summary, heart rate monitors use sensors to measure heart rate and offer a variety of functions to monitor the intensity of physical exertion and optimize training in cycling.

The choice of heart rate monitor for cycling depends on your specific needs and the features you consider most important. 

Remember that the choice depends on your personal preferences and the characteristics you find most important for your specific needs. Evaluate the features, the budget, and read user reviews to make an informed decision.

To calculate the maximum heart rate (MHR) in cycling, you can use the general formula 220 minus your age. However, this formula is an approximate estimate and can vary individually. A more accurate method is to perform a stress test under the supervision of a health or training professional. During the test, your maximum heart rate achieved during intense effort is measured. This will provide you with a more precise value for your MHR and allow you to establish target heart rate zones for targeted training in cycling.

The placement of the heart rate monitor depends on the type of sensor used. Here are some common options:

Optical heart rate monitor on the wrist: 

These devices should be worn around the wrist, positioned snugly but not too tightly. Make sure the optical sensor is in direct contact with the skin for an accurate heart rate reading.

Chest straps: 

Chest straps are placed around the chest, under the breasts. Ensure they are positioned securely, but not too tight, and that the electrodes are in direct contact with the skin.

It is important to follow the specific manufacturer's instructions for the correct placement of the heart rate monitor, as guidelines may vary slightly from one model to another. Also, ensure that the device is compatible with your wrist size or chest circumference for optimal performance.

Before use, it may be helpful to slightly dampen the contact area of the sensor to improve conductivity and achieve a better heart rate reading.

In general, it is important to ensure that the heart rate monitor is positioned stably and correctly to obtain accurate readings during training or competition.
