How To Choose The Most Accurate Fitness Trackers?
Most fitness trackers have heart rate monitoring because it is very important, can show the health status of a normal person. Besides, you also need to consider some important features like counting steps and estimating calories burned.
But how to choose a highly accurate fitness tracker? In fact, the answer to the accuracy of a fitness tracker depends on what you expect from it. That is, what purpose will you use it for?
For example, if you are expecting a product to help you track your health condition, you only need accuracy in monitoring your heart rate. On the other hand, if you are a gym-goer, you will need a fitness tracker that can accurately estimate the calories you have used for your workouts, etc.
- The more steps you take each day, the healthier your body will be. With a fitness tracker, you can set a goal of 10,000 steps a day to accomplish. Check your step count on two different devices to compare accuracy.
- Besides, many products are underestimated because they do not count the number of steps when the wearers take the stairs or pull strollers. Therefore, you should also check the product carefully before buying it.
Heart Rate Tracking
- Most fitness trackers measure the heart rate very well when people are at rest, but some are inaccurate when they are doing exercise. This is because you sweat during work out, leading to an incorrect heart rate measurement on the device. Therefore, check it with a chest strap to make sure its accuracy.
Calories Burned Estimating
- This is the most complex factor, so it is difficult for a fitness tracker to measure. However, in order to get the most accurate results, make sure you give the tracker information about your body's weight, height, muscle and fat percentage, and some information it requests, such as activities you are performing like jogging or cycling.
Which Brands Make The Most Accurate Fitness Trackers?
- Garmin is a company specializing in GPS technology and has a quite high age, about 30 years, and was founded in the United States. Their area of operation is very wide, ranging from technology for sports activities to technology for cars, aviation, and maritime. After that, they have researched and developed strongly in wearable technology, becoming a competitor to big names in the world such as Apple or Fitbit, especially in terms of the accuracy of their products.
- Lintelek may not be a well-known name like Garmin, Apple, Samsung, or Fitbit, etc. However, their products have been recognized by users from more than 50 countries around the world and that number is constantly increasing.
- You can trust their new technology, which gives high accuracy in algorithms to measure human health indicators. Besides, their products are very affordable, which creates a competitive advantage for them.
Does a fitness tracker overestimate calories burned?
Unfortunately, there are many well-known fitness trackers that overestimate your burned calories when you exercise. That's why you need to research thoroughly before choosing to buy the most accurate fitness tracker.
How accurate is a fitness tracker for calories burned?
- This is what some products may give you false information.
- Anything you do uses up to a certain amount of calories, and many people still use walking as an activity to burn off their calories. As you exercise with greater intensity, such as cycling, jogging, climbing stairs, etc., your calorie burned will increase.
- In general, different activities will use a separate calorie level. Because fitness trackers are not connected to your body but measure it on the wrist, the information they provide is based on estimates and combinations of indicators. That's why sometimes, the calories burned that you see on the face of the fitness tracker will be lower or higher than the actual number.
- The choices we provide above are no exception. However, they are the best options for many different purposes, so you can rest assured to use them.
Are smartwatches worth it?
- For those who are looking for a fitness tracker that looks strong and stable, they can opt for a fitness watch. It has more features than a regular compact fitness tracker, and as a result, its price is also much higher.
So should you buy a fitness watch?
If you have a decent budget with texting, calling, photography, music, exercise instructions, and especially the ability to sync with your phone and laptop, etc., then a smartwatch is the right choice for you.
If not, I recommend not investing all the money you have with an additional loan on these products.
Maybe this is just my personal opinion that the concept of technology is not a trend but a convenience. However, aside from the cost disadvantage, you will be wasting the features of the smartwatch if you do not need to use them.
Can fitness trackers detect heart palpitations?
You can know a lot about your overall health if you know your heart rate. Through fitness trackers, you can track the signs related to it and find out if your body is having a problem.
While fitness trackers still have limitations on absolute accuracy, manufacturers are still aiming for them to become a medical device, not just a workout buddy. Therefore, smartwatches and fitness trackers with heart rate monitoring can accurately measure fluctuations in your heart rate.
If you notice your heart rate suddenly rising rapidly and surpassing the normal resting rate, I recommend you visit your doctor for a cardiac health check.
Besides, the heart rate measurement feature will also help you exercise more effectively. That is, which activity and level of the workout will best suit your body.
Is it better to wear a fitness tracker on the dominant hand?
At first, I had the same opinion on this issue. But, it seems to go against the advice of the manufacturers.
They recommend that you wear a fitness tracker on your non-dominant wrist, which is, if you're left-handed, wear it on your right hand and vice versa. The reason is that when you are right-handed, your right arm will work continuously and more than the left-hand does. This may result in some metrics, such as the number of steps, being skewed.
It is best if you can choose the most accurate fitness tracker. Otherwise, your motor process may be affected and ineffective. Therefore, do not forget to carefully consider the factors making up an accurate fitness tracker that we have guided.
