For someone on a fitness journey, the Apple Watch feature that calculates calories burned can be a huge help. But if you’re tracking calories, you want to make sure you are on the right track. How does the Apple Watch calculate calories burned? Is it accurate? We answer these questions and more in this article.
To calculate the calories you have burned, your Apple Watch uses the personal information you provide such as your height, age and your weight. It uses your heart rate and movement to measure your activity and exercise also. This tracks the number of calories you burn daily. The more accurate the information you provide is, the more accurate the feedback will be.
When swimming, your arm motion determines the results you get from your Apple Watch. It also studies your strokes over time to give more accurate results. A lot of things could affect your swimming calorie results. For example, using swimming aids like fins, not using your arms, or stroke actions that your watch does not recognize or accept as valid.
The Apple Watch calculates resting calories using the same data used in calculating your active calories. Information such as your gender, height, weight, the GPS in your iPhone, and data from its own built-in sensors, are used to calculate your resting calories and the calories you burn during exercise.
Obviously, your watch does not know how much weight you are lifting. The calories burned during strength training are calculated exactly the same way as other exercises – by using the information available, its sensors, and also tracking the duration and intensity of your workout, since the Apple Watch allows you indicate the type of exercise you’re engaging in and for how long, it can give a rough estimate of the calories burned.
We believe the Apple Watch is as accurate as it can be for calculating calories burned. Based on your personal information and your movements, your Apple Watch estimates the number of calories burned during your workout using an algorithm. It also tracks your movement and your resting calories to provide even more useful information for your fitness journey. If your personal information is not accurate, it will definitely affect the results you get from your Apple Watch.
To make sure you always get accurate results from your Apple Watch, ensure your watch is always properly fitted on your wrist. And always keep your personal information up-to-date.
This is surprisingly a very common problem, and one likely reason for this is that your health information might be outdated. To get the most accurate results at all times, update your personal information regularly. Here’s how you can update your personal information.
Access the Apple Watch app from your iPhone. Click on the “My Watch” tab, and open “Health”. Under health, open “Health Profile”. Tap Edit, then make any necessary changes.
It could also be because your Apple Watch is not in contact with your wrist. Your watch needs to be properly fitted on top of your wrist for you to get accurate results. A loose or poor-fitting watch can affect the accuracy of your results.
Lastly, ensure that your watch is not in Low Power Mode, or that you haven’t enabled Workout Power Saving Mode. This could contribute to the inconsistencies.
Well, this is easy. Each person has a different body type. Your gender, height, weight, heart rate, and other information cannot be the same. So, even if you do the same workouts, it is unlikely that you will get the same results. This is just how your bodies work.
Yes, bigger people burn more calories on Apple Watch. But it isn’t just that. Bigger people burn more calories in general. Since they weigh more, they have more energy to burn.
Yes, they do. Again, they weigh more. Naturally, they have more energy to burn.
Apple Watch has exercise rings that track your movements, exercise, and standing calories. How does it do that?
Whenever a full minute of movement goes past the intensity required for a brisk walk, it is counted under your daily exercise or move goals. To determine what is recorded as a brisk walk for you, the Apple Watch Series 3 or later models use your cardio fitness levels.
Running burns about 10.8 to 16 calories per minute on average, making it the workout that burns the most calories. You can also record a lot of calories by hiking, bicycling, skipping at a fast pace, swimming, or brisk walking. Other exercises such as yoga or strength training might not present the same results. This is because of the system with which the algorithm works.
The Apple Watch ECG is very accurate.
A single-lead electrocardiogram (ECG) can be derived from the Apple Watch Series 4, Series 5, Series 6, or Series 7 ECG app. While it cannot be used to detect some major heart conditions (for example, heart attacks), it can be super helpful for monitoring the underlying rate and rhythm of your heart.
Some Apple tests checking the ability of the Apple Watch ECG app to correctly classify an ECG recording into AFib and sinus rhythm have come out with promising results. As a matter of fact, a clinical test with about 600 subjects came out with a 99.6% correctness rate when compared with the 12-lead ECG usually administered by doctors.
While it is likely that a test taken in real life might produce more classifications with inconclusive results, there is no doubt that the Apple Watch is very accurate.
