The two groups that reach the peak of human endurance? Extreme athletes and pregnant women

The average person can burn up to 4,000 calories -- a limit a group of scientists consider the peak of human performance -- before depleting the body's energy stores. And while extreme distance runners reach maximum performance during high-intensity races, expectant mothers often hit the same mark at a lower intensity over a longer period of time, typically without completing a triathlon.

Athletes were able to maintain their intensity for short periods of time, but when competing in longer, high-intensity events, they weren't able to replenish the calories they burned throughout the day. "You can do really intense amounts of work for a day or so," Herman Pontzer, a Duke University researcher who co-led the study, told CNN."But if you have to last a week or so, you have to maintain less intensity.
