![]() ![]() Readings from a chest strap will remain unaffected by motion artifacts, always giving you a precise value. These types of workouts entail lots of body movement for which wrist heart-rate monitors using optical sensors weren’t designed - maintaining on-target HR measurement with all that movement and rapid HR changes involved generates inaccuracies. That’s why precision is so important, particularly during HIIT routines or running intervals. Sometimes long-term inconsistencies in the HR reading can negatively impact your training goals. How your heart performs while you’re exercising is equally important - knowing your HR is crucial to make a training session an absolute fitness-boosting killer or an endurance-improving activity. For example, how quickly or how slowly your heart recovers from an intense activity can tell you a lot about your fitness. If you’re an ardent athlete, everything pertaining to your heart directly translates into your overall fitness and the efficiency of your training. Learn more Heart Rate Accuracy during Workouts Learn how to work in a workout―and make it really effective. With those basic differences out of the way, let’s now focus on why such precision is better for your training.ĭon’t let exercise be the first thing to fall off your busy schedule. Heart rate variability calculated from ECG has a better signal-to-noise ratio during the workout than from the optical sensors ![]() This type of HR measurement - electrocardiography (ECG) - isn’t affected by ambient light during sports and is in turn much more accurate (99% of accuracy compared to a hospital-grade ECG device). Certain conditions, e.g., ambient light, moisture, or thick skin, will affect the reading.Ĭhest straps, on the other hand, use small electrode pads to collect electrical signals of the heart. While this is a relatively precise method to measure HR, it’s not the best one during workouts. Wrist heart rate monitors use optical sensors to calculate heart rate. Optical sensors are often exposed to external noise sources, leading to inaccurate readings Now let me expound why and why that matters in your training. So why do I think a chest strap is better than an optical wrist heart rate monitor (OHRM)? Short answer - a chest strap is more accurate. The restless heart of an athlete being no different. But, as is often the case, the more we have, the more we want. ![]() With the current state of wearable technology, reading and collecting biosignals is a real feast for health and sports enthusiasts. ![]()
