Metabolic range of humans?

depends on the person
if you want a rough idea then find out how many calories someone burns during maximum hiit training, then divide that by average metabolic rate (again in calories...find a figure anywhere)
sure there will be some error due to non oxidative ATP production (ie carbs) but itll give you an idea, and it is dimensionally consistent...

yes there is but i didnt think it was applicable since it would measure average O2 consumption over the whole time the athlete was in there- NOT peak
for peak youd have to use peak O2 consumption, and i think they do that somewhere..but im no longer in the mood to find it for you

i guess the bigger the person the more oxygen that person requires.

no duh.
however mass is not proportional to metabolism. the larger the organism the more efficient. For example an elephant weights 10,000 times more than a mouse but only needs 1,000 more calories.
In a nutshell there are biological economies of scale in being a mammal.

The calorie requirement ratio you posted is inaccurate. An average caloric intake for an 8 ounce mouse may be 10 calories while an average caloric intake for a 10,000 pound elephant may be 100,000 calories. The elephant needs about 99,990 more calories than the mouse.Lumberg said:
The basal metabolic rate, the number of calories needed for body maintenance, is higher for larger animals than smaller ones. However, as animal size increases, the proportional metabolic rate rises more slowly.
The discrepancy between metabolic rates in reference to animal size is explained simply by the energy source exploited by the animal. (Larger animals eat mass quantities of food with a less dense caloric component, while smaller animals exploit a much smaller volume of more caloricaly dense foods.)

I'm curious what a cheetah's is at - there is also a antelope like thing that is chased by the cheetah that has insane speed over distance.
The VO2max formula includes weight (well, mass) in there. That is why just losing weight makes one that much faster with no other training. Also why you will never see a muscled dude winning the marathon.
On a side and vaguely interesting note, I recall learning that horses stand one large advantage in endurance races - under stress their liver can produce more glycogen on demand, where humans on the other hand will run out and that is it (the "bonk" that is famous in marathons and triathlons - the point at which you deplete your glycogen stores - for a highly trained athlete, that is at about 20-22 miles or roughly 2 hours in - for an untrained at the equivalent exertion level would be 1-1.5 hours).

Sorry I meant to say that while weighting 10,000 times a smuch as a mouse an elephant needs only 1,000 times as many calories. So your second paragraph is dead on and what I was trying to say.
It has more to do with the efficiencies of scale of circulatory systems as well as a disproportionate increase in mass vs. surface area. As we know surface area is where an animal loses heat.
OMGWTFBBQ If you bump this thread later on I will post the entire table that I found (it's in a book I own not online). I don't think cheetahs or antelopes are on there, only domesticated animals but I'm not sure.
