Heart rate monitors come in different types, each with its own advantages and disadvantages. The three most common types of heart rate monitors are chest strap, armband, and wrist-worn devices.

Chest strap heart rate monitors detect the pulse electronically and send the data to a receiver, such as a smartphone or a wrist-worn tracker. They are similar to the sensors used in hospitals and are highly accurate. However, they can be uncomfortable to wear for extended periods.

Armband heart rate monitors are a newer type of monitor that slip on to the upper or lower arm. They are more comfortable than chest straps and easier to put on. However, they may not be as accurate as chest strap monitors.

Wrist-worn heart rate monitors, such as those made by Fitbit, Apple, or Garmin, use light to monitor the heart rate. The light is reflected by blood vessels passing through the veins, and the device calculates the heart rate using an algorithm. While they are more convenient to wear, they are not as accurate as chest or armband monitors.

Type of Heart Rate Monitor Advantages Disadvantages
Chest Strap Most accurate, reliable, and durable option Placement can be difficult for obese people or women
Armband Convenient and comfortable to wear Less accurate than chest strap
Watch Easy to use and wearable throughout the day May not be as accurate as chest strap or armband

 

*If accuracy is a top priority, chest or armband monitors are the way to go. However, if comfort and convenience are more important, wrist-worn monitors may be a better choice. It is important to consider personal preferences and needs when choosing a heart rate monitor.

Things to Consider Before Buying

When looking for a heart rate chest strap monitor, there are a few things to keep in mind. These factors will help you find the best monitor for your needs.

Bluetooth VS ANT+ Monitors

When choosing a monitor, it’s important to consider the connectivity options. Bluetooth and ANT+ are the two most common connectivity options. ANT+ sensors can be connected to multiple devices at once, while Bluetooth devices primarily work in a 1-to-1 connection. Most smartphones come with Bluetooth, but not ANT+. It’s important to consider which connectivity option will work best for your needs.

Extra Features and Battery Life

Some monitors offer extra features like cadence metrics, vertical oscillation, and ground contact time. These features may be important for some users, but not necessary for others. It’s important to consider which features are important to you. Additionally, battery life is an important factor to consider. Unlike smartwatches, chest strap monitors can last for months or even years on a single battery charge.

Strap Width

Strap width is a matter of personal preference and comfort. It’s important to choose a strap width that feels comfortable during exercise.

Optical VS Electric HRM

Most chest strap monitors use electric pulses to read heart rate, while optical sensors use a strong, often green light to shine through skin and track blood flow. While some believe that electric monitors are more accurate, there is no real-world testing to prove this. All smartwatches use optical sensors for heart rate monitoring.

Why Heart Rate Chest Straps are the Best

Heart rate chest straps are considered the most accurate and reliable option for monitoring heart rate during exercise.  According to a 2019 study, the Polar H7 chest strap was the most accurate when compared to an ECG.

The Polar H7 chest strap was the most accurate, and the Apple Watch was superior among watches. For endurance athletes and their coaches, a chest strap device or Apple Watch may be the best choice for guiding workouts and performance – ncbi.nlm.nih.gov

According to a study, chest straps provide more accurate readings than wrist-worn or armband monitors. This is because chest straps are able to detect the electrical activity of the heart, while wrist-worn and armband monitors rely on optical sensors that can be affected by factors such as skin color, tattoos, and movement. Additionally, chest straps are more durable and less likely to move during exercise, providing more consistent readings. Here are the 5 best ANT+ or Bluetooth heart rate chest strap monitors to get in 2024:

What’s the difference between ECG and optical heart rate sensors?

Heart rate monitors are a valuable tool to have for measuring effort on the bike. There are two types of heart rate sensors: ECG and optical. ECG heart rate monitors measure your heart rate by measuring electrical signals in your blood. Based on these electrical signals, an ECG heart rate monitor measures the timing and strength of your heart rate. On the other hand, optical heart rate monitors measure a person’s heart rate using light to track blood flow variations. By shining a low-intensity light through your skin, the sensor can read fluctuations in blood flow beneath the skin and determine your heart rate.

Chest strap

For a very long time, measuring heart rate meant wearing a chest strap. These utilise electrodes pressed up against your skin, and electrocardiography to log your heart’s electrical activity. Regardless of the price point, HR chest straps are surprisingly accurate, with some options like the Polar H10 claimed to measure your heart rate to a granular degree of accuracy. This isn’t just bike industry hokum, a 2017 research letter in the Journal of the American Medical Association Cardiology found a chest strap had a 99 per cent correlation with an electrocardiograph and another 2017 study published in the Journal of Medicine and Science in Sport and Exercise found a Polar H7 to be in 99.6 per cent accurate when tested against an ECG. The pads need a bit of moisture to pick up the electrical pulses coming from your heart, so they may need a few minutes once you get sweating to spit out an accurate reading.

Many people have a love-hate relationship with chest-based heart rate monitors, as the elastic strap can be uncomfortable, or slide down over the course of a ride. Most use a detachable pod that houses the hardware to broadcast the ANT+ and Bluetooth signals, a coin cell battery and sometimes accelerometers, gyroscopes, and perhaps a bit of memory, which can record running metrics and even full activities. However, these snaps are usually the Achilles heel of the chest strap as the constant exposure to sweat can cause them to corrode to the point of interference with the signal coming from the electrodes. Sweat sneaking past the weatherproofing on the battery door can also be an issue.

Optical heart rate

With the proliferation of fitness trackers worn on the wrist – such as Apple watches, Fitbits and the Wahoo ELEMNT Rival – we have also seen widespread adoption of optical heart rate monitors. Optical heart rate has been around for many years in the medical setting with the finger clips that read heart rate through Photoplethysmography (PPG). Optical heart rate sensors also come with quite a few caveats, especially when it comes to accuracy. There are best practices for how they need to be worn (tight, above the knuckle on your wrist), and accuracy can be affected by skin tone, hair, moles, and freckles. Because of these variables, two people wearing the same model watch or HR sensor can have different levels of accuracy. Again there has been no shortage of testing in both the bike/fitness industry and peer-reviewed journals, which has shown that their point-to-point accuracy can vary from +/- one per cent to error rates as high as +/-13.5 per cent found by this 2019 study in the Journal of Sports Science.

To no small degree, the source of this variation is due to how the heart rate is read and where it is taken. Optical heart rate requires the sensor to remain locked onto the skin to maintain its accuracy. When you start to shake it around – like on a bike ride – even if the watch or sensor is tight, it still moves around a bit, which makes its task hard again. This is backed by a 2018 study published in the Cardiovascular Diagnosis & Therapy, which tested a variant of optical HR sensors on runners, who, throughout the test, would run on a treadmill that would increase in speed. As the intensity of the workout increased, the accuracy of the optical heart rate sensors decreased. Then there is the variety of sensors and algorithms being used. Some use three LEDs; some use two, others use just green, while others still used tri-colour LEDs, which means that some will be more accurate than others.

Should You Choose an Armband or a Chest Strap Heart Rate Monitor?

When it comes to choosing between an armband or a chest strap heart rate monitor, it ultimately depends on personal preference and what type of physical activity you will be engaging in.

Chest strap heart rate monitors are the traditional type of heart rate monitor and are widely recognized as the best heart rate monitor device, with 99.6% accuracy when worn correctly. These devices record the electrical activity of the heart using electrocardiography. Because they directly measure your heart rate rather than your pulse rate, the sensor is closer to your heart than a wristband, which allows it to capture a stronger signal. This gives them a higher level of accuracy, regardless of whether you are running, cycling, or resting. Chest straps are also more reliable during high-intensity workouts, as they are less likely to move around.

On the other hand, armbands or smartwatches with optical heart-rate monitors are accurate while walking or resting and can also be used for running and cycling. They use light to measure blood flow and detect the small expansions of blood vessels beneath the skin’s surface. However, optical heart-rate monitors can be inaccurate if you move too much during your workout, as your movements and fast pace can push the device around. Additionally, they are less accurate than chest strap monitors, with a variance in heartbeat readings.

Many people prefer armbands or smartwatches over chest straps due to their convenience and comfort. Chest straps require a moisture-water pad to pick up an electric signal, making it more challenging to use than the wrist- or forearm-located monitors. Chest straps can also be too restrictive for breathing and may cause discomfort during workouts. In contrast, armbands and smartwatches are easier to adjust for comfort, easier to wear, and can be removed more easily.

Overall, if accuracy is your top priority, a chest strap heart rate monitor is the best option. However, if convenience and comfort are more important to you, an armband or smartwatch may be a better choice. It’s essential to consider your needs and preferences before making a decision.
