““A well-conditioned oarsman or oarswoman competing at the highest levels must be able to take in and consume as much as eight liters of oxygen per minute; an average male is capable of taking in roughly four to five liters at most. Pound for pound, Olympic oarsmen may take in and process as much oxygen as a thoroughbred racehorse. This extraordinary rate of oxygen intake is of only so much value, it should be noted. While 75–80 percent of the energy a rower produces in a two-thousand-meter race is aerobic energy fueled by oxygen, races always begin, and usually end, with hard sprints. These sprints require levels of energy production that far exceed the body’s capacity to produce aerobic energy, regardless of oxygen intake. Instead the body must immediately produce””
