Equations for calculating calories burned through exercise


Firstly i would like to apologise for the length of this post, and thank anybody who will take the time to read it!

My name is Tom Ruddock, and i am a final year Computer Science student at the University of the West of England, Bristol. For my final year project i am currently attempting to create a computer program which can be used to create a gym training schedule for gym members.

I am having some trouble finding any information regarding how to calculate the amount of calories burned during a certain exercise for a specific person. There are many programs which do exactly what i would like my program to do, which is simply to take a persons age and weight, and for many different gym exercises create the amount of calories they would burn doing that excercise, given the time spent exercising at whatever level of resistance the machine is set to. I am yet to find any information regarding the equations programs like these would use in order to calculate this.

I realy have become stuck with this so any help anybody could give me with this would be greatly appreciated. If anyone knows of these equations or where i could find them that would be fantastic. Failing that, if anyone could point me in the direction of other information or resources i could use to find this information, that would be just as helpful.

Thanks in advance for anybodys help.

Go to google and type "how many calories do I need?"

There are all sorts of websites that include what you will burn with witch activity. Some take into consideration your weight and height.

good luck!

Since you have obviously found all of the activity-calorie calculators, I'd suggest looking into (a) the concept of METS and (b) the heartrate as an indicator of exertion. Sorry I can't be more helpful, but I've never had much success in finding out for my own knowledge what factors other than weight are involved in those calculations.

I found this:

How Did You Calculate Calories Burned by Exercise?
As you can see from the form above, the formula for calculating calories burned during exercise takes into account several factors:

* the type of exercise performed
* the total duration you performed the exercise in question
* your body weight

In addition, the formula takes into account the so-called METs (metabolic equivalents), which are an expression of how intense each type of exercise is.

If you are curious, the actual formula looks like this:

Calories burned by exercise = ((METs * 3.5 * weight in kg) / 200) * duration in minutes.

One MET equals 3.5 milliliters of oxygen per kilogram of body weight per minute -- which is what our bodies require at rest. The more effort an activity requires, the higher its MET value. (Walking briskly at, say 3.5 miles per hour, burns 3.8 METs per minute.) That value is the same for most of us, regardless of fitness level.

...sorry, I see that you were looking for the formula used, not just the websites!
