How Accurate Is the Calories Burned on Samsung Gear S2

"Fitness trackers out of pace when measuring calories, inquiry shows," The Guardian reports. An independent analysis of a number of leading brands found they were all prone to inaccurate recording of energy expenditure.

Researchers recruited 60 participants to accept part in a range of exercises while having their heart rate and number of calories burned measured by fettle trackers, every bit well as by clinically-canonical medical devices used in a clinical setting. Seven fettle trackers were tested, including the Apple Watch, Fitbit Surge and the Samsung Gear S2.

The data from the fitness trackers was compared against the information obtained by the clinically-canonical devices to summate whatever errors in the measurements.

The researchers found that although fitness trackers are mostly reliable in their ability to measure eye charge per unit, they perform poorly when measuring the number of calories burned. The results showed that, out of all seven devices, the Apple Spotter had the everyman fault in measurements whereas the Samsung Gear S2 had the highest level of mistake in terms of center charge per unit measurement and the PulseOn in terms of calorie burning measurement.

For now, fitness trackers remain useful for individuals to have an idea of how many calories they may have burned over a mean solar day but information technology should be kept in mind that these devices are not always 100% accurate, as shown by this study.

And if you lot are trying to lose weight, focusing on an overall weekly goal for exercise and activity may exist a meliorate approach than trying to mensurate every single calorie burning exercise from one 24-hour interval to the next.

Where did the story come from?

The study was carried out by researchers from Stanford University in the U.s. and the Swedish School of Sport and Health Sciences in Stockholm. No external sources of funding were reported.

The study was published in the peer-reviewed Journal of Personalized Medicine. The article is bachelor on an open admission basis, which ways it'due south free to read online.

Uk media coverage on this topic was by and large authentic.

What kind of inquiry was this?

This was an experimental study that assessed how accurately seven fitness trackers are able to measure out middle rate and calories burned compared to a "gold standard" cess of heart charge per unit and energy expended in an practise laboratory.

Commercially available fitness trackers are increasingly being used by individuals as office of fitness monitoring or weight loss programmes. The results from the devices are often compared to average population levels and in theory could inform decisions made by doctors. Prior to this report the accurateness of the information produced by consumer trackers hasn't been evaluated in slap-up detail.

This type of report is a useful fashion to compare the different trackers against a "gilt standard" measurement and volition help individuals determine how much trust they can accept in their devices.

What did the research involve?

The researchers chose fitness trackers which:

• are worn on the wrist
• continuously measure heart rate
• take a battery life of more than than 24 hours
• were available to consumers at the time of the study

Seven fitness trackers were evaluated:

• Apple Watch
• Basis Peak
• Fitbit Surge
• Microsoft Ring
• Mio Blastoff ii
• PulseOn
• Samsung Gear S2

60 participants (29 men and 31 women) over the age of 18 were recruited to take part in the assessment. Participants were selected to represent a diverse range of age, height, weight, skin tone and fitness level.

The individuals wore the fitness trackers while sitting, walking, running and cycling. They were simultaneously monitored using clinically approved instruments: electrocardiograms (ECG) and continuous clinical form indirect calorimetry.

Indirect calorimetry is a laboratory techniques for measuring fettle in which the maximum oxygen intake while breathing on the treadmill or bicycle ergometer is measured and a standard formula is used to estimate free energy expended. It was used hither every bit a gold standard for measuring calories burned.

The data from the fitness trackers was analysed confronting data from these clinically approved instruments. Heart rate from the fitness trackers was compared with data obtained from the ECG and the number of calories burned was compared with the data from the indirect calorimetry. The percent of error in relation to the clinical devices was and then calculated.

What were the basic results?

Overall, the researchers plant that nearly fettle trackers were able to measure heart rate fairly accurately, merely poorly estimated the number of calories burned.

Of the seven fettle trackers, the Apple Watch performed all-time whilst the Samsung Gear S2 had the largest errors when measuring heart rate and calories burned.

Middle rate:

• The Apple Watch achieved the lowest error when measuring heart rate: two.0% (1.2%-2.eight%).
• Samsung Gear S2 had the highest mistake: 6.8% (iv.vi%-9.0%).

Calories burned:

• The Fitbit Surge performed best with the lowest error of all seven trackers: 27.4% (24.0%-30.viii%).
• PulseOn had the highest error: 92.6% (87.five%-97.7%).

How did the researchers interpret the results?

The researchers concluded: "We assessed, in a controlled laboratory setting, the reliability of seven wrist-worn devices in a diverse grouping of individuals performing walking, running and cycling at low and high intensity. We constitute that in virtually settings, heart charge per unit measurements were within adequate error range (5%). In contrast, none of the devices provided estimates of energy expenditure that were within an acceptable range in any setting.

"Individuals and practitioners should be aware of the strengths and limitations of consumer devices that measure heart rate and estimate energy expenditure."

Determination

This report assessed how accurately seven fitness trackers are able to measure the heart rate and calories burned of individuals taking office in several different activities. The data was compared against clinically approved medical devices to exam the accuracy of data obtained by the fitness trackers.

It institute that although all seven trackers were fairly accurate at measuring heart rate, there was a loftier level of error when measuring the number of calories burned.

The researchers hope this study will help individuals and physicians be aware of potential errors when interpreting the measurements obtained by fitness trackers, peculiarly when using the information to inform treatment options in a clinical setting.

This is an interesting study but information technology is small and would crave farther testing of devices with a larger number of participants to verify the findings. For at present, fitness trackers remain useful if you lot want to compare information on yourself over time, but they shouldn't be relied upon if you're trying to replace calories burned with a "treat".

If your goal is to lose weight through practice, then comport in mind it'due south very much a "marathon not a sprint". Increasing your activeness and exercise levels on a long-term basis is more important than obsessing near exactly how many calories you may take burned during a single run or gym session.

The NHS weight loss plan is designed to assist you lose weight, through a combination of diet and exercise, over the course of 12 weeks.
