Armband VS chest strap heart rate monitor, which is better?

Armband and chest strap heart rate monitors are doing the same things but in different ways. They all can guide you while training and can keep your workouts more effective. When we choose, we would like to know them well first.

The principles of heart rate detection are different.


Each heartbeat of the body produces cardiac pacing current. The heart rate chest strap is such a device that can sense the cardiac pacing current. The sensor’s pole piece is located on both sides of the anterior end of the chest strap. When wearing the chest strap, the pole piece in it collects the user’s fluctuation of the cardiac pacing current. It is then transmitted to the heart rate meter through wireless transmission technology and converted into a heart rate BPM value for observation. This is the mainstream and more accurate method of measuring the exercise heart rate.

HRM60 heart rate monitor

An optical heart rate monitor measures the light absorbance of the hemoglobin in blood vessels to monitor the pulse. The heart rate sensor is equipped with an infrared beam emission circuit and a reflection-receiving circuit. The advantage of this heart rate measuring method is that it is very simple and does not need a chest strap. However, due to the extremely weak signal that is much vulnerable to external interference, this method may result in an inaccurate measurement result. In addition, it usually needs to work in a quiet environment.

HRM80 armband heart rate monitor

Magene HRM80 heart rate armband can collect the variation data through the photodiode and calculate the heart rate. With the dual-beam array, you can acquire more accurate detection data and capture real-time heart rate changes more efficiently.

Performances in different sports


For running, cycling, and regular dynamic exercise, the heart rate armband is fully competent for heart rate monitoring and its data accuracy is close to that of the chest strap. The advantages of the armband also include convenient and comfortable wearing and a long time of continuous working, taking the Magene HRM80 armband, for example, can last up to 45 hours of workout after each charging. It is currently applicable to most physical sports such as running and cycling.

In this respect, the armband wins!

However, it was found that in other exercise tests such as Bobby jumps, where blood is in weightlessness and hypergravity, the performance of real-time heart rate monitoring of the armband is less stable and accurate than that of the chest strap. Only about 5 seconds after stopping exercise can it return to normal.

The principle of the optical heart rate sensor is to calculate the heart rate by measuring the changes in the light reflection signal of the blood in the arm/wrist. But, in Bobbie jumps, where the blood is weightless and overweight, the optical sensor cannot process filtering, thus resulting in inaccurate data measuring. The heart rate chest strap, however, has no such trouble. It calculates the heart rate by measuring weak changes of electrical current in the human body through an electrode.

So, from this perspective, the chest strap wins!


Above all, the armband outperforms the chest strap and is comfortable wearing while the chest strap enjoys a higher accuracy.
The armband is more suitable for sports where hand strength can be kept stable, such as running, cycling, yoga, etc. The chest strap is more suitable for the most intense exercises and can meet the need for professional heart rate monitoring.

Fat On Which Body Parts Can be Reduced by Riding a Spinning Bike

You can lose fat on your hips, abdomen, and legs by riding a spinning bike. To avoid heat or chill, many people choose to ride a spinning bike in the gym or at home, which helps them lose weight effectively. It is recommended that you combine cycling with other activities to lose weight all over.

Legs

While riding a spinning bike, your legs get exercised the most. As you need to keep pedaling with muscles on your legs, fat on these parts is consumed quickly to make your legs slimmer.

Abdomen

While riding a spinning bike, the muscle group of your abdomen is exercised along with the moves of your legs. This activates your abdomen and makes it firm.

Hips

While riding a spinning bike, you need to use the muscles of your legs, waist, and hips. Hence, the muscles of your hips can be better exercised to become tight and attractive.

Riding a spinning bike as a safer and more efficient type of aerobic exercise is becoming increasingly popular. So what factors need to be considered to select a bike suitable for you? Here you can find the answers (how to choose a spin bike).

Exercise is good for your health but excessive exercise isn’t. No matter how good the course may be, riding a bike on a daily basis is not recommended.

Riding a spinning bike is an aerobic activity, so it takes some time for you to recover after doing it. Riding a spinning bike every day can be harmful to your knees. It is recommended that you ride it while also arranging other physical activities. Three to four times a week is the optimal frequency to ride a spinning bike.
