The data delivered by health trackers has been the subject of numerous comparative studies in order to verify its veracity and to compare the reliability of these objects with each other. These digital trackers that we wear on ourselves have been the subject of a study on the precision of the measurements they deliver, such as heart rate, VO2 max, energy expenditure, sleep monitoring and the number of steps.
While heart rate appears to be measured fairly accurately, with a margin of error of around 3%, the measurement of energy expenditure – this is the assessment of the number of calories burned during physical activity – appears to be much more approximate.
The margins of error recorded depending on the devices used vary between -21.27 and 14.76%, which is significant. The same goes for sleep, the time of which tends to be overestimated – by 12 to 180%. While these data paint an overall picture of your physical activity, it is advisable not to take them literally but rather to monitor the overall variations.
Data galore
The inventory of data collected by connected objects dedicated to health is so vast that it can be dizzying. This data, delivered in disarray, is recorded in dedicated applications; it is more or less hierarchical and processed. The processing of health data is opposed to a strict legislative framework, which explains their lack of perspective.
While trackers are able to fairly accurately detect anomalies in cardiovascular functioning via the collection of heart rate and ECGs enabled by some of them, it is forbidden to extract a medical diagnosis from them. Therefore, the interest of these technological marvels is limited. Manufacturers are not lacking in imagination, like Garmin and its Body Battery indicator which gives an image of the energy reserve based on the compilation of data collected by the watch.
This indicator, although interesting and relatively well designed, is not based on any scientific basis and offers a figure closer to common sense – everyone knows if they have slept enough – than to the physiological reality of each person. These data, which are not put into perspective, are lost in dedicated applications and are often rarely consulted by users, with the exception of the number of steps which remains a fairly popular piece of data.
Are these connected objects useful? Not very useful for health monitoring, as the data that can be extracted from them is not very usable without medical advice. However, athletes remain fond of the phenomenal amount of data they collect on their performances, which gives these devices a reason to exist. wearables.
If you are a fan of numbers, the era being relatively accounting, then you will be delighted with these objects. But, if you are neither sporty nor looking for data, then move on while waiting for future developments, such as blood sugar or blood pressure monitoring: these will certainly give added value to health trackers that have not yet reached maturity. While waiting perhaps for the contribution of artificial intelligence, which could revolutionize data processing.

– Are wearable health trackers an effective tool for monitoring fitness and health?
The Truth About Wearable Health Trackers: Accurate or Just a Gimmick?
The world of wearable technology has taken the health and fitness industry by storm, with devices tracking everything from our daily step count to our sleep patterns and heart rate. Apple’s latest smartwatch, equipped with sleep apnea detection, is just the latest addition to this growing market. But how accurate are these devices, and can we really trust the data they provide?
A Sea of Data, But How Reliable Is It?
Wearable health trackers have been subject to numerous studies to verify the accuracy of their measurements. While heart rate monitoring appears to be relatively accurate, with a margin of error of around 3%, other measurements such as energy expenditure and sleep monitoring are much more approximate. In fact, the margin of error for energy expenditure can vary by as much as -21.27 to 14.76%, while sleep time can be overestimated by 12 to 180%.
The Limitations of Health Data
While these devices can provide a wealth of information about our physical activity and health, it’s essential to take the data with a pinch of salt. The processing of health data is subject to strict legislative frameworks, which means that manufacturers are not allowed to extract medical diagnoses from the data collected. This limits the usefulness of these devices for health monitoring, as the data is not actionable without medical advice.
The Dangers of Misinterpretation
With so much data available, it’s easy to get caught up in the numbers and lose sight of the bigger picture. For example, Garmin’s Body Battery indicator, which claims to provide an image of our energy reserve, is not based on scientific evidence and is more of a rough guide than a reliable metric. Similarly, the number of steps taken in a day can be misleading, as it doesn’t take into account other forms of exercise or physical activity.
So, Are Wearable Health Trackers Worth It?
While wearable health trackers may not be as useful for health monitoring as we might hope, they can still be a valuable tool for athletes and fitness enthusiasts. The sheer amount of data collected can be motivating and help individuals track their progress over time. However, it’s essential to remember that these devices are not a replacement for medical advice or professional guidance.
The Future of Wearable Technology
As the wearable technology market continues to evolve, it’s likely that we’ll see even more features and capabilities added to these devices. Apple’s sleep apnea detection is just the beginning, and we can expect to see more advanced health monitoring features in the future. However, it’s crucial that manufacturers prioritize accuracy and transparency, providing users with reliable and actionable data that can be used to improve their health and wellbeing.
Conclusion
Wearable health trackers can be a useful tool for those looking to track their physical activity and health, but it’s essential to approach the data with a critical eye. By understanding the limitations and potential pitfalls of these devices, we can make the most of the information they provide and use it to make positive changes in our lives.
