Wristbands with optical monitors should be worn just above the wrist bone, or about two-fingers width from where your hand meets your wrist. While that makes wristbands easier to wear, they can also be moved out of place more easily. Unlike a chest strap, wristbands are much easier to adjust for comfort and fit. Movement can disrupt the accuracy on an optical heart-rate monitor, mostly because the fast-paced movements you do when you're working out can push the monitor around on your wrist. In comparison to electrocardiography and chest straps, PPG and modern wearables offer more ways for users to mess with the system's accuracy. They've gotten better over the years, and considering PPG isn't a new, it's not an inherently flawed way of capturing heart-rate data. There's little flexibility when using a chest strap, and while that can make them uncomfortable for some users, it's also a big reason why they're consistently accurate.īut optical heart-rate monitors in more convenient or comfortable devices aren't totally unreliable. In that case, the pads would be off-center or even positioned against your back rather than your chest. No matter which style you have, you can't adjust the placement of the electrodes unless you twist the entire strap around your body. Some chest straps just have one central electrode that sits in the middle of your chest, just underneath the breast bone, while others can have two electrode pads that hug the inner portion of your rib cage. Also, the electrodes are typically fixed on the strap, so you can only fiddle with the placement so much. This lets medical professionals more comprehensively assess the electrical activity of the heart, and chest straps simplify this method because no one wants to attach multiple sensors to their body when they go for a run.Īnother reason why chest straps tend to be more accurate than wristbands is that there's less room for user error. As long as you purchase the right sized strap, it's very difficult to wear a chest strap too loosely-the strap would just fall down to your waist. When doctors and nurses use ECG machines to assess patients, they place up to 12 leads on various parts of the patient's body, most of them going on the chest around the heart. There are specific reasons why chest straps are more accurate in general: most importantly, the sensor is placed closer to the heart than a wristband is, allowing it to capture a stronger heart-beat signal. The biggest reason many athletes prefer chest straps to wrist-mounted monitors is accuracy. People like to criticize wristbands for being grossly inaccurate, and, in their infancy, this reputation was earned. With many chest straps, you now have the option to connect them to another wearable or simply use a compatible mobile app to record and save pulse data. Before people started using mobile apps as their sole receivers, heart-rate chest straps sent their information to old-school fitness watches that showed the data on their displays. Using Bluetooth and a connected smartphone, the transmitter can consistently send heart-rate data to your mobile device, which acts as the receiver. Inside is a microprocessor that records and analyzes heart rate from those electrical signals, as well as a battery and the chips needed for Bluetooth connectivity. The transmitter is typically the only part of the chest strap that is detachable. When you're working out and sweating, the electrodes pick up the electrical signals given off by your heartbeat, and they send that information to the transmitter. That pad needs moisture water or sweat to pick up any electrical signal. This process requires electrodes, which live in the shiny, flat pad against the skin. These heart-rate monitors work differently than the ubiquitous wrist-bound monitors on new wearables because they use electrocardiography to record the electrical activity of your heart. Most of them are made of a long, belt-like elastic band that wraps snugly around your chest, a small electrode pad that sits against your skin, and a snap-on transmitter. Heart-rate monitoring chest straps are both loved and hated. However, their key differences in methodology and design will dictate which device you choose when picking a workout companion. According to Harvard's Health blog, your resting heart rate is a key factor to determining your overall current and future health, and monitoring heart-rate changes over time can give you more of the information you need to lead a healthy life.Ĭhest straps and optical heart-rate monitors are the two most common types of pulse trackers available for modern wearables, and they both use similar methods to measure your pulse. Learning your heart-rate patterns, both during a workout and during daily activity, can show you a lot about your health. If you want to get a fitness tracker, you have to decide is if you want one that's compatible with a heart-rate monitor.
