Exercising is unfortunately more than just putting one foot in front of the other when you go for your weekly (or yearly) jog. There’s the nutrition, your body composition, the science – all of which can make your head spin. But if you’re looking to get to the next stage, you’ll often have to look deeper into these areas to get a better idea of how your body works, and how you can make it work better.

Fortunately, with science and technology progressing in leaps and bounds over recent times, there’s no shortage of gadgets, apps, articles and advice available at your fingertips to help you get the edge over your PB. But are they all necessary? In this Canstar Blue guide, we’ll look at one of the most common pieces of exercise technology you’ve likely come across – the humble heart rate monitor – and whether it’s worth setting your heart on purchasing one.

Heart rate monitors explained

While the hint’s in the name, a heart rate monitor gives you information around (you guessed it) your heart rate. While you will see plenty of machines that do it in a hospital, portable heart rate monitors have been around for decades, and have been used for a similar amount of time in the fitness industry to monitor athlete’s heart rates while they rest and exercise. Over recent years though, they’ve become much more accessible, meaning they’re no longer just for professional athletes.

How do heart rate monitors work?

How do heart rate monitors work

Heart rate monitors work by tracking your pulse, which is when your heart pumps blood around your body. How heart rate monitors actually do this will depend on the type of monitor you have, with some monitors operating by electrocardiography – which is essentially tracking your heart rate through the electrical activity of your heart – while others use what’s known as photoplethysmography (or PPG), which uses light to measure blood flow via wavelengths.

The PPG method is common with wrist-worn fitness trackers and monitors, while electrocardiography is more common with chest strap monitors.

From here, each monitor will measure your heart rate and transmit that data to the receiver (which is usually the wrist-worn component of the monitor) where you’ll be shown that information to discover what your heart rate is in real-time.

Are heart rate monitors accurate?

Accurate heart rate monitors

The accuracy of heart rate monitors has often come into question, particularly as you’re primarily wearing them when you’re exercising, and likely very sweaty. You can argue that the accuracy of heart rate monitors will come down to the user (such as making sure you put it on properly), but can a heart rate monitor give you an accurate measurement when you’re moving around?

A study published in Cardiovascular Diagnosis & Therapy showed that chest strap monitors were the most accurate out of the devices tested, although also highlighted that the accuracy depended on the type of exercise the subjects undertook, with steady-state cardio on a treadmill giving the most accurate results.

What’s the difference between a heart rate monitor and a fitness tracker?

With fitness trackers now a popular fitness gadget, are heart rate monitors still worth buying? It depends on what you’re after, as most often fitness trackers will monitor your heart rate in addition to keeping track of your exercise time, how many calories you burn and other fitness information, while a heart rate monitor will generally solely focus on your heart rate. So, if you want something simple, a heart rate monitor may be the one for you, while if you’re after a bit more info from your workout, a fitness tracker may be the best fit.
