I'll have to see if my is accurate by calibrating as you suggest and see how close I can get it. Then I can use my own caloric burn rather than someone elses.

I hear ya on the power meters with all the other toys that come with it. When I think I'm in the market for a new cycle computer I will push for the bigger toy because then I will have been in the sport long enough to prove to myself and DW that this sport is no longer a fad but a healthy life style that will continue for the rest of my life.

Jim,

Good questions. I use an older Polar Ti HRM. I've been using this one for about 5 years. With Polar HRM's to calibrate you must measure your resting rate for one minute. What I did was rest without any noise for 15 minutes, I then did the test and was able to get an accurate rate. As with most HRM's it is important to update the information on a regular basis. HRM's, when being set up require your age, weight and height. These all change, so accuracy is up to you. I also run the calibration about every 6 months, because my resting rate has decreased over the years. The industry within the past 5 years has made significant improvements, when it comes to measuring. If you want "true data", get a power tag for the bike. But be prepared to spend the money. I am currently in the market for a new computer and at the top of my list is the new Mavic Wintech Ultimate USB. It has cadence, HRM, altimeter and all the other crucial functions for riding.

I love the insight .... I have read that this is still aguess on calories consumed with heart rate monitors because it does not take into consideration of elevation change, wind, etc.

Have they improved that much now to be more accurate?

If I might ask, which heart monitor do you use? If you can send a private post or reply here on how you calibrated the HRM to your specified self to give accurate caloric burn.


Thanks,

Jim

You aren't stepping on toes. HRM are used for calories as well as heart ranges and are designed to be used during exercise, Bodybugs are worn 24/7, for the most part. Before Bodybug HRM's were used to count calories, before that it was purely a guess. Just like Bodybugs, HRM's also have to be set up for the specified user. When I'm riding my food intake is based off of calories burned, I.E. energy. The rule of thumb is food intake every hour, even more if you are riding hard. The food I consumed this year during my three multi century rides were based off of caloric output. In one case, when I was doing a lot of mountain climbing at high elevation I burned over 7,000 calories and that day was a 70 mile training ride. During that ride I consumed 10 bottles of watter, one large Gatorade four bananas and 8 power bars. My breakfast was a massive bowl of whole wheat pasta and my dinner before consisted of a carb over load. My heart rate was low, compared to other days, because I focused on leg strength over cardio. 6 years ago I had a professional trainer and had an oppurtunity to use a Bodybug, but decided to use the HRM instead. The results I saw was extremely positive and this is why I still use it to this day.

I think you are mostly right. The heart rate is best used as a guide to how hard you work. 2 people of equal weight can do the same amount of work yet the one with the stronger heart will have lower bpm. I only use mine to control my workout intensity.Calorie burn is an estimate always.

I think the intent and purpose of a heart rate monitor is being misconstued. If you want calorie intake/calorie burn then buy a bug like is being used for the biggest loser show. The heart rate monitor intended purpose is to measure what your heart is doing at any given level of exercise. This is done so that you do not over train or under train.

In my case for me to burn off my stored fat for energy needed in a work out I should remain in Target zone 2 for the duraton of my exercise after a proper warm up and cool down.

I hope I did not step on any toes or muddy up the waters. I think it is important to use the tech gadgets for their intended purpose. Yes the heart rate monitor does show calories burn but is it truly a reflective picture of what you are burning? Unless you calibrated everything properly I do not think it is? Is it a ball park figure? Yes it is .... but it sounds like you are wanting a more precise measure? Just my pennies worth.

I'll wait and see what else is chimed in. I have been known to be off base in the past;-)

Here's how I look at it - I'm trying to balance my calorie intake against my calorie usage in such a way that I burn a little of my stored fat at a time.
The formula that SparkPeople uses to determine my daily calorie needs takes into a count a base amount of calories someone my size would probably use during a sedentary day, and the number of extra calories I tell it I'll burn through exercise during the week.

Since I can't directly input that base amount, I really only need to keep track of the calories I burn though exercise to make sure I'm hitting the target I set for myself. That means, I don't bother tracking my heart rate or calories burned for general daily activity. At least not for the purposes of balancing calorie input and output. It can be interesting and informative to track your resting heart rate, and heart rate recovery, but I only have so much energy to spend on the numbers.

I think the key here is to understand your reasons behind tracking your heart rate and calorie burn, and apply those numbers as needed in order to reach your goal.

I wish you all the best,
Terri

Carlorie burn is interesting info though not real useful. The most important number is heart rate as this tells you how hard you are working and how you cool down and recover. it also tells you when you can work harder.

I use my HRM whenever I go for a run, to the gym or for a ride. I then document all my data, high HR, Low HR, Avg, HR, Cal. burned and in zone times and place all the information in an Excel spread sheet. In the far right column I have my body weight and BMI %. I also subscribe to mapmyride.com and document my mileage and evelvation gains. This way I can cross reference all my information and see where I trully am for fitness. Right now it is ugly, but by Mid April, I'll be back to where I was last year, that way the remainder of the year I only become better than the previous year.

I wear mine during bike rides and exercise. Well, I would wear it but the battery is dying and I have to send it back to Polar for a replacement battery.

In general though, I use it during fitness. I guess if someone was figuring out for stats purposes how many calories used in a day and when hr peaks it may be handy. I don't think I'm that curious.

I use mine for exercise only, however I would say this is a personal choice.

When you exercise, that is when your heart rate should be up to 85% of max and calories will be burning

When to wear HRM?
(question cross-posted)

I am trying to lose weight. I track what I eat so I can monitor my calories, fat, protein, carbs and fiber using a journal. I try to exercise everyday with my rest day being an active rest day like walking.
Anyway, I wear my heart rate monitor (HRM) during exercise and burn anywhere from 300 calories to 1000 calories (long runs). Some of the other people in my weight loss group wear their HRM all day.
I have been only tracking the calories I burn during actual exercise.

Should I wear mine all day? All day or for exercise only?

Lovey



This is the year of a healthier me.
Nothing tastes as good as skinny feels.
