Calories burned on a treadmill

djackins

I am very very new to this. I bought a treadmill about 4 months ago and I walk at speed 4.0 for about 60 minutes at incline 3.0 or 3.5 and it shows me I burned 700 calories. I have read that this is almost impossible. How am I to really know how many calories I am burning? It's a brand new treadmill. A friend of mine does about the same thing too and hers shows right about the same thing but she also heard/read that it's not correct but she just had hers calibrated. Can someone help me? I need to know
how many calories I am burning for my daily excercise deduction.

You can purchase a HRM and get a good estimate of how many calories you are burning.

When I used to walk on the treadmill, I would walk for 45 minutes at right about 4 mph and I weighed about 170. My HRM gave me a calorie burn of 300.

Unless you can create a profile adn add your weight and height, everything else is an educated guess.
Please get your self a HRM for correct calories burned.

Forget the HRM, it is unlikely to give you an accurate number as all it is doing is math-guessing similar to what the treadmill is doing.

net calories burned walking = 0.3 * body weight in pounds * miles walked

This assumes 2% incline on treadmill. Going to 3 or 3.5% won't make a meaningful change in the number.

Case in point re: HRM. Actual burn was 150, HRM over-estimated by 100%.

Not sure that sounds quite right either.

45 minutes at 4 MPH = 3 miles total @ 15:00 (a fairly brisk walking pace). A 170 lbs person should be burning more than 50 calories per mile.

I hope I am not doing the math correctly because I weigh 132 lbs and walk for 4 miles and I'm coming up with 158.4 calories burned? Please tell me that's wrong.

It's correct.

For the mythical "average" person, going at 4mph will burn slightly more than going at 3.5mph, but the difference at this distance is on the order of 10-20 calories.

how long does it take you to go 4 miles?

djackins

About 60 - 62 minutes

I went to the runnersworld.com website you just posted and put in my weight, time and miles and it showed me I burned 399 calories. I like that number ALOT better then the 158. :happy:

this calculator has them burning ~ 300 for 170 lbs. person walking 3 miles in 45 minutes

this other calculator comes to 298

it's just math (force = mass x acceleration or something like that)

that's running - at 15:00 pace you could either be fast walk or slow jog

check those other calcs I posted for walking - I'm thinking 300 sounds about right

you can't even really go by that either, the more you perform an exercise, the easier it becomes, the easier it becomes, the less you have to exert to perform, the less you have to exert to perform, the less calories you burn.

JAllen32

You burn about 100 cals per mile. Give or take a small amount based on weight. 300cals for 3 miles in 45mins is fairly accurate. You can always underestimate if your worried about it and log an even 250.

?? I just bought a Polarft4 HRM for this very reason as others told me it would give me the most accurate amount of Calories burned?? :indifferent: Isn't the point of the heart rate monitor is to gauge by how hard your heart is working???

For as accurate a measurement of how many calories you burn, an HRM is best. However, as a really, really, loose guide if no HRM is available, 100 calories per mile, so walking for one hour at 4mph, means you walked 4 miles = 400 calories - this is a pure estimation but it is not too far off the mark.

My own treadmill gives me exaggerated readings too, but it only really matters if you eat all of your exercise calories back, if you only eat some or none of them back, it doesn't matter how many it says you burn.

I have read an article about cardio that stated that you can not rely on the tredmills and machines to count how much calories your body has burned, each indiviual burns at different rates. Just know that if you put your body under physical stress you will burn calories. You said you walk at an incline of 3.5 i would raise it to 14.5 and walk around 3.5 the more stress the better.

Thank you all for all your help. I sure do appreciate it!
