Fitness Trackers – The Truth Behind Heart Rate and Calories Burned My EPIC RANT!!!!

There is an equation for figuring out a persons maximum heart rate and fat burning heart rate. The fat burning heart rate is based on the maximum heart rate.

It is important to note that these equations are not suitable for determining safe heart rates for children.

To calculate the maximum heart rate, a person should subtract their current age from 220 . For example, a 40-year-olds maximum heart rate would be 180 beats per minute.

To calculate the fat burning heart rate zone, a person should determine the upper and lower limits. The upper limit is 70% of the maximum heart rate. The lower limit is about 50% of the maximum heart rate.

Using the same example, a 40-year-olds fat burning heart rate is between 90 and 126 beats per minute.

People interested in increasing their endurance and cardiovascular strength often train at higher levels. Sometimes called the cardio zone, people training for performance increases often train at 7085% of their maximum heart rate.

The following chart shows the breakdown of heart rates based on a persons age.

How Accurate Are Heart Rate Monitors

Chest straps are still considered the most reliable and accurate heart rate monitor but are not as easy to use throughout the day as other wearable fitness trackers.

The factors mentioned above suggest that wearable monitors are more likely to provide a best guess result since they do not utilize all the physiological data required to calculate an absolute accurate answer. It does not mean that the figure calculated by the monitor is completely useless, though.

The accuracy of heart rate monitors when tracking your heart rate alone is really good. Numerous studies have been conducted on the more famous brands of heart rate monitors, and results proved that the accuracy of wearable heart rate monitors in relation to tracking just heart rate was less than 10% different from gold standard medical instruments, which is extremely impressive.

The discrepancy in results relating to calories burned ranged up to 27% between the same two instruments. Thats a significant difference but illustrates the potential issue with relying solely on your monitor to track your calories.

About The Formula We Use For Calories And Heart Rate

We use two different formulas for the calculation. One for women and the other for men. The formula can only be used if the heart rate is between 90 and 150 beats per minute. If you calculate with a heart rate lower than 90, the calculation will not be correct.

Men:Calories per minute = + + ) / 4.184

Women:Calories per Minute = – + ) / 4.184

Check out the table below to get an idea of how much calories burned as heart rate increases. We have counted on this with a person of 30 years. If you are under 30 years old, the numbers will be slightly lower. If you are older, the number of calories burned is higher. We did our calculations for a time period of 60 minutes. Use the tool above to calculate your personal calorie consumption at a certain heart rate.

Calculating Daily Calorie Burn

Calorie burn calculators are an easy way to track how much youre burning during your workout. If you want to know how many calories youve burned, the calculator will tell you! You can find calorie burn calculators on most fitness apps or websites these days. Heres what they do and how to use them:

Step 1: Find Your Target Heart Rate

The first step is finding your target heart rate zone by using a formula that takes into account your age, resting heart rate, and physical activity level. This number might be different for everyone depending on their goals. Once you figure out this number, input it into the calculator along with the duration of time spent working out.

Step 2: Calculating Calories Burned

The second step is to input your weight into the calculator, along with how long and what intensity level of exercise youre doing in order to calculate an estimate of how many calories you burn per minute during that workout. For example, if Im running at a moderate pace for 30 minutes, I would input .75 miles into the calculator. The speed of your run or weight lifting is not important only that youre doing it at a certain level of intensity.

Step 3:Apply the Formula

You can also get an estimate by using this formula: OR x .07) + )

Major Factors That Affect The Accuracy Of Results

Heart rate and calories burned ânot enough dataâ? i...

Different cardio and strength training exercises have different effects on your heart rate and overall metabolism. When muscles contract, the bodys reaction is to increase your heart rate and pump more blood to that area.

During cardio training like running or cycling, your muscles undergo repetitive expansion and contraction, which causes blood to flow to the muscles when contracted and away to the rest of the body when expanded. Therefore, the quick repetitive motion in cardio training causes a more constant blood circulation and heart rate.

Alternatively, strength-based training like bodybuilding and yoga works a little differently. The blood flow to the muscles is not pumped back as quickly. This reduced blood return from the muscles causes the brain to increase the heart rate even further. Therefore, your heart rate monitor will almost always overestimate the number of calories youve burned during these exercises due to the increased heart rate and the subsequent impact on your metabolism.

Ways To Measure Your Heart Rate

If youre now thinking about measuring your heart rate to see how effectively youre burning fat, there are a number of ways in which you can do so, with many of them thanks to modern technology:

  • Use a heart-rate monitor. These gadgets are available in most sports shops, and they are usually attached to the body using a strap. They measure your heart rate while youre exercising, and many of them nowadays can be linked with a computer to view your results more comprehensively.
  • Use a smartwatch or FitBit-type device. The next generation of smartwatches are geared towards those who like to keep on top of their fitness many of them send notifications if youve not reached your step target for the day, or if they detect youve been sitting down for too long! FitBit-type trackers can also measure your heart rate and help you decipher whether youve hit the target rate yet.
  • Go old-school: check your wrist and neck periodically. Taking your pulse manually can help you pinpoint your heart rate you only need to hold it for ten seconds to get an accurate idea of how fast your heart is beating, then multiply that value by six, eg If your heart rate is 15 beats per 10 seconds then your heart rate per minute is 90 beats per minutes

    What The Research Says About Polar Heart Rate Monitors And Calories Burned

    The last example is more promising: In a study published in the September 2010 issue of the âJournal of Sports Science and Medicineâ, scientists evaluated the validity of the Polar S810i heart rate monitor against an armband monitor for estimating calories burned during indoor rowing. The small pool of 43 participants were monitored via indirect calorimetry to provide a baseline for accuracy of the devices under trial.

    Like the other fitness tracking device used in the test, the Polar S810i heart rate monitor was shown to significantly overestimate energy expenditure during low-intensity exercise. However, there was no significant difference between the Polar results and the indirect calorimetry results at moderate exertion levels, and the overall results still correlated well at low intensities.

    Overall, the researchers decided that despite the variability at low intensities, results correlated well enough for the Polar heart rate monitor to provide accurate calories burned estimates. But they went on to note that for that to be true, the heart rate monitor had to be programmed with the exerciser’s measured VO2max and maximum heart rate, as opposed to the estimated values you typically have access to outside a clinical setting.

    Factors Affecting Calories Burned

    The number of calories a person burns by performing a given activity is dependent on many different factors. Most estimates involve the use of three key factors: body mass, duration of the activity, and the metabolic equivalent of a task . The MET of various tasks have been widely studied, and our calculator estimates calories burned based on data made available through these studies.

    Body mass and duration

    A persons body mass affects how many calories they burn, even at rest. A person who is larger due to more muscle, fat, or height burns more calories. This is also true during exercise since the body has to do more work to provide energy to a larger person than it would to a smaller person. Thus, a person who weighs 200 pounds will burn significantly more calories running 1 mile than someone who weighs 100 pounds, given that other conditions remain the same.

    Duration of exercise is another factor that affects calories burned. The longer a person performs an exercise, the more calories they will burn. However, the relationship is not as simple as it is with body mass because the intensity of the exercise matters. For example, a person who walks 1 mile in 1 hour will burn significantly fewer calories than someone who walks 5 miles in that hour.

    Exercise intensity

    Oxygen consumption is measured in MET . There are a few different definitions of MET. The original definition, and the one used by this calculator, is based on oxygen utilization and body mass.

    Keep Track Of What You Eat Too

    For people who need accountability, Im in favor of using an app to track what you eat. A free downloadable food diary, such as Lose It! makes it easy to spot patterns and notice when youre running into trouble say, a daily afternoon stop for M& Ms or a routine bagel breakfast. Tracking can also add an element of mindfulness. Just knowing that you have to input what you eat may allow you to push the pause button and think for a moment about whether its worth it. And seeing that a handful of pretzels can set you back 100 calories might help you pass them up, particularly in light of the fact that youre probably not burning as many calories as you think you are.

    And if you still enjoy the feedback from a wearable device, note that Apple Watch had the most accurate readings. Making sure you have a snug fit may also improve accuracy. You need good contact with your skin, says Scherbina. But perhaps think twice before gifting a tracker to the man in your life. Though the calorie burn was inaccurate for everyone, it was worse for men than women, she notes.

    How To Estimate Calories Burned By Heart Rate

    Heart Rate Based Calorie Burn Calculator

    Using your average heart rate during an exercise session, you can estimate the calories that you expend while working out. Your heart rate is directly related to your calorie expenditure rate. This calculation will be most accurate when your heart rate is between 90 and 150 beats per minute . The equation used to calculate calories burned also requires weight, gender and duration of the exercise session.

    Weigh yourself on a scale. Ensure you measure your weight in pounds.

    Wear your heart monitor while you exercise, but wait until your heart rate gets above 90 bpm before recording it. Keep your heart rate between 90 and 150 bpm by slowing down or speeding up as necessary. Complete your exercise session and stop recording your heart rate before it drops below 90 bpm. Your heart monitor should give you your average heart rate for the whole session once it stops recording.

    Estimate the calories that you burned during your exercise session. For women, this is given by the equation C = x T / 4.184. C is the number of calories that you burned, H is your average heart rate, W is your weight, A is your age and T is the length of your exercise session in minutes. Assume that youre a 28-year-old female weighing 146 pounds. Your average heart rate during an exercise session that lasted 36 minutes was 138 bpm. You burned C = x 36 / 4.184 = 301 calories.

    Measuring Your Heart Rate

    While you can use the heart rate calories burned calculator without knowing your exact heart rate, it definitely helps to measure it.

    One way to measure your heart rate is to do it the old fashioned way. This is where you feel your pulse with two fingers on your wrist or neck. Then count the number of beats in 15 seconds and multiply by 4 to get beats per minute.

    Another option is a heart rate monitor. These days there are countless wearable devices that will measure your heart rate. However, not all of them are accurate when youre moving around.

    For the best accuracy during exercise, I recommend a chest strap device. Like the Polar H10 Heart Rate Monitor.

    Ive used Polar heart rate monitors for at least 5 years. And Ive found they provide consistent and accurate heart rate tracking compared to other devices.

    How Accurate Are Smart Watches Blood Pressure

    Smart watches are becoming increasingly popular as a way to monitor ones health and fitness. While many people believe that smart watches are accurate, there is some debate about how accurate they actually are. One study found that while smart watches were generally accurate when it came to tracking heart rate, they were less accurate when it came to tracking blood pressure. Another study found that while smart watches were accurate when it came to tracking steps, they were less accurate when it came to tracking calories burned. So, how accurate are smart watches when it comes to blood pressure? While they may not be perfect, they are generally accurate and can be a useful tool for monitoring your health.

    The pulse pressure of the two devices was calculated. The p-value of a paired-sample t-test was calculated to compare mean, SD, subtype, and vehicle type. P values were not calculated if neither night-time smartwatch measurements nor data from each patient were available. According to the Taffé method, bias and precision are non-constant measures, and they are determined by an estimated realBP . When measuring wristwatch measurements, look at the 24-hour cutoff. As a result, the smartwatch overestimates the systolic blood pressure by approximately 140 mmHg. For gold standard methods, higher precision measurements were obtained, whereas lower precision measurements were obtained for smartwatches.
