Groundworks - Calories per hour?

This will take a little time but it will be as accurate as possible.
Search for "Compendium of Physical Activities"
The site will have a very comprehensive list of activities with an MET value.
That is a multiplier for your Basal Metabolic Rate (BMR)
MFP and other sites have BMR calculators

- determine your BMR, the calories per 24 hours.
- find your activity in the Compendium of Physical Activities and the associated MET
- Multiply your BMR * MET to find calories per 24 hours.
- divide by 1400 to find calories per minute.
- multiply by how many minutes

I love the two posts answering your question. Both helpful but so different.

MFP and other sites probably base their calorie estimates on the Compendium. HRMs are fine, there is probably a site to log your HRM and activity.

Just for giggles, I extracted the PDF to Excel and wrote a spreadsheet for calculations. I should really create a small site that calculates against all the activities. BTW, if you see "Taylor Code" mentioned with activities, it is a taxonomy, a numeric code for each activity. E.g., general body building and weight lifting is Taylor Code 210.

There are two cautions to consider when using the Compendium as a resource:

1. Many of the occupational-type activity values are based on doing continuous work, with no pauses or breaks.

2. The Compendium is based on collections of research studies. The authors of the compendium admit that there is no systematic process of evaluating the accuracy quality of studies admitted into the compendium. So the reliability of the values is variable.
