Compendium of Physical Activities

The Compendium of Physical Activities (PDF) estimates your energy expenditure during common activities.
1 metabolic equivalent (MET) is the baseline energy usage of a person quietly sitting. Sitting still all day is unhealthy, so leave a comment (typing = 1.5 METs), put away your groceries (2.5 METs), belly dance (4.5 METs), or chop wood with an ax, fast (17 METs).
The full list starts on page S505 (8th page). Alternate links.

p.s. I know three of the authors and should have just asked them.

Sitting and reading takes 30% more energy than sitting and doing nothing? How's that figure? I didn't think books were that heavy.

I would venture to claim that if your 14010 burns less energy than the 13020 that precedes it, you're doing it wrong.

I like that they've blocked out a hundred codes for future possible "Religious Activities" indices. I guess then we'll be covered for things like "Full Immersion Baptism" or "Circumambulating a Stupa"...
Note that the link here is to an article on updates to the list, not the full list. (A somewhat more complete, but I think still partial list, is here.)

Thanks aught, I thought it was the updated list, not updates to the list.

Okay, my favorite game so far is finding an activity I frequently perform (swing dancing) and then finding things that are metabolically equivalent (scraping and painting sailboat, caulking, planting trees, feeding cattle, forestry with power saw, orange grove work(?), social badminton, walking briskly and carrying objects less than 25 pounds.)

I think the next release of this document should have a further break-down of bicycling as an activity... but that's my favorite thing to do and I would hazard to guess that most folks don't get up to an 8 MET when they ride a bicycle. And I'd hazard to guess that pro cyclists do well above a 12.
And how does one calculate aggregated tasks? I mean... if your thing is vigorous skin-diving while having vigorous sexual activity and light reading all at the same time what would your MET be?

The brain burns up a lot of resources. This is why blood sugar can be important to concentration, and, when people have serious blood imbalances, loss of awareness and stupor-like symptoms are one of the first things EMTs check for.

Severian, go to page S505 for a little more bicycling detail broken out by speed. Too bad they don't factor in hills as they do for walking, to some degree, on page S514.
It's all still pretty subjective, though. From page S515: "Walking to and from an outhouse: 2.5 METs". What about degree of urgency/force of clenching, walking uphill to the outhouse versus walking downhill back? "Walking, for pleasure, work break: 3.5 METs". Well, what if you;re going to the outhouse during your break?

I find it hard to believe that running 8-minute miles (12080, 12.5 METs) takes more energy than "boxing, in ring, general" (15100, 12 METs).
Absolutely agree. At 73 I run an 8 min. mile easily. Two ACTIVE minutes in the ring would exhaust me.

Take it from the authors: Standing (2.0 METs) requires more energy expenditure than "active, vigorous" sex (1.5 METs). Reaaalllly?
This leads me to question the accuracy of their values regarding other activites, including mild stretching (2.5 METs) and standing (bathing dog, 3.5 METs).

I need to 14010 a whole lot more. But I guess that's a given.
If you didn't head right for the 14s there is something wrong with you. Just a warning.

Is there a conversion algorithm for METS to KCals?

Nevermind: weight (in kg, kg = lbs/2.2) * METS = KCals Burned per hour

Given the amount of time I spend at 16 (>20mph on a bicycle), you'd think I'd have reached my weight goal a long time ago. Alas, I'm a glutton. The Tour will have to wait.

It would be inappropriate to use this to try to estimate calories burned during exercise. You cannot simply assign a number to an activity and have it apply universally; there are numerous ways that one person can expend more or less doing the same activity as another, and I'm not just talking about bodyweight. Even the authors of this thing remind you that its only value is in comparing one activity to another:
It should also be stressed that the Compendium was not developed to determine the precise energy cost of PA within individuals, but instead to provide an activity classification system that standardizes the MET intensities of PAs used in survey research. This limits the use of the Compendium in estimating the energy cost of PA in individuals in ways that account for differences in body mass, adiposity, age, sex, efficiency of movement, geographic and environmental conditions in which the activities are performed. Thus, individual differences in energy expenditure for the same activity can be large and the true energy cost for a person may or may not be close to the stated mean MET level as presented in the Compendium.posted by Rhomboid at 4:37 PM on July 15, 2010
I'd really like to see a breakdown of Jack Torrance's MET throughout the film of The Shining.
Breaking down door with axe: 12.5 MET
Chasing son through maze in deep snow: 15.0 MET

From the tiny energy expenditure that's listed, I think they're doing it wrong.

I'm unsure what to classify my biking as. I usually average around 22-23 km/h, which is about 14 m/h. However, I'm doing that up and down hills, on a hulk of a bike with not-exactly-fast tires, on dirt roads. So I'm either at a 10 or a 12 MET.
Even at a 10, with my weight I supposedly burn about 1000 KCAL/hour. Like klanawa, that feels like I should have lost more weight.

The danger of reducing life to a spreadsheet: the two kinds of sex become "heavy activity" and "moderate activity."

My theory is that in the interests of decency, they've hidden all the interesting sex activities under various euphemisms, like moving furniture (6.0), scrubbing floors (3.8), or sawing hardwood (7.5). Laying sod, using crutches (both 5.0). Eating at church (only 1.5).
