Understanding Heart Rate Monitors

Basic Facts of Heart Rate Monitors

The health of your heart is the key to your overall physical health, and you can’t ignore it if you want to live long and healthy. A physical exercise is a good way to keep you fit  but the life style of today’s population specially those living in metros are just challenging their own body clock. Work Pressure, Improper Sleep, pollution are some of the very common factors, from which you can’t escape.

So, with exercise, you should definitely need some device, which will seamlessly monitor your health and keep you updated about your health statistics.

Fitness trackers are invented for same purpose, they measure your real time heart rate and not only record your heart rate

but also able to track your day-to-day activities as how many steps do you walk and how many calories you burn. It also provides feedback on sleep and can give you various modes of exercise like swimming, walking, running and cycling.

There are varieties of HRM available, if you deciding to get a heart rate monitor for exercise you must look for the one that are equipped with Heart Rate sensor and compatible to monitor your heart rate and able to track your heart patterns during different activity as of day whether it is workout or daily actions.

Before you should move on find the appropriate model for yourself, you have to gather some information on heart rate. Go to this Link if you want to learn more>> Normal Heart.

Now if you understand your heart rate it is time to find out the types of heart rate monitors available in marketplace.

There are two types of technologies used in hr monitoring devices that is an electrical and other is an optical. However, these are simplified names to general consumers; in medical terms the electrical sensing technology refers as Electrocardiography (ECG) and Optical Technology refers to photo-plethysmo-graphy or PPG. Both technologies used sensors to monitor heartbeats but both of them are use in different designs.

Electrical Sensors Designs:

Electrical Sensor Technology is use in Chest Strap Monitors. It measures the electrical signal created by your heart.  It functions like the typical ECG machine means you have to applied some liquid at-least some water under side of the pad before using it because that pad need some moisture to pick electrical signals. The electrical signals picked up by the electrodes send to the processor that record and analyse the rate and pattern of the heartbeat from those electrical signals. The data recorded is send to the receiver via ANT+ or blutooth to your mobile devices.

Optical Sensor Designs:
Optical Sensors are the most widely recognized heartbeat sensors in wearables.  Wearables with optical pulse screens have little LEDs on their undersides that sparkle green light onto the skin on your wrist. The various Wavelength of light from these LED’s connect contrastingly with the blood moving through your wrist. At the point when that light contact off your flowing blood and reflected or refracted, another sensor in the optical wristband catches that light and convert it into data. That information would then be able to be handled, alongside movement data identified by the gadget’s accelerometer, with calculations to deliver justifiable heartbeat readings.

At present most fitness, trackers are wristbands in which a wristwatch like optical heart rate monitors commonly tied on your wrist.  While some others are ear bud type, and some of them you have to put on your temple. No matter where the device used, but it uses the same PPG technology of analysing light refracted off flowing blood to measure your heart beat.

Question about Accuracy:

Chest Strap is useful when you are in condition to monitor your heart rate very closely like athletes or a heart patient. Since the sensor is positioned near the coronary heart, permitting it to seize a more desirable heartbeat signal like ECG machines used to examine the patient heart by sticking anodes to different places on body. While taking a data from the arm or wrist is more challenging because it swing rapidly during activity creating errors in reading thus lead to incorrect results. Though Chest Strap measure accurately yet people find them uncomfortable in wearing all time and often complaints of skin rashes if wore for long time.

As far as optical heart rate monitors is concerned they are more comfortable and this is not to say that all wrist-band-optical heart-rate monitors are incorrect. Some preform brilliantly while others provide less accurate data. Since with modern technology they are much more scientifically developed and improved over the years and are easy to carry.

Optical Wristband are worn just above the wrist bone, If the band moves too low or too high on your arm, It will get you an inaccurate reading.  Although the movement can disrupt the accuracy on an optical heart-rate monitor due to fast-paced activities of your wrist or hand but if you tight the wristband gently on your wrist, movement shouldn’t be much of an issue. Fitting is extremely important, but you should also look out for how tightly you wear your fitness-tracking wristband. If worn it tightly, the band can hinder your blood flow—even if your optical wristband can pick up a signal, it will not be correct because blood cannot flow through your wrist naturally and if you wore it too loosely, space and air can prevent the Optical Wristband from monitoring your heartbeat. Your heart-rate tracking wristband should fit comfortably enough so that it cannot move on your wrist without you moving it yourself, but loosely enough so you don’t feel bound or annoyed by its company.

Which one you use

I recommend a chest strap for anyone considering heart-rate zone training. Those like triathletes, marathon runners, athletes preparing to compete during a particular activity or sport, and therefore like should invest in a chest strap because most of them offer flexibility on top of consistent accuracy.

However, for people who are very active and have specific goals to satisfy with their fitness drills should accompany optical wristband based heart-rate monitors. They are far easier to wear, you can adjust them quickly even while you’re in motion, and that they don’t cause chafing. They will even have LEDs that flash different collars counting on your pulse zone. You cannot get that visual feedback from a chest strap alone. Usually with chest straps you’ve got to rely on a connected tracker to check your pulse rate numbers.
