The amount of oxygen used by the body in metabolism is proportional to the energy yield, with 1 liter of oxygen combining with foods to produce about 20,000 joules. If the oxygen consumed in one minute is 1.5L during vigorous exercise, what is the metabolic rate in watts (i.e., what is the average power during this minute)?
1 answer
1.5 * 20,000J / 60s = 30000/60 = 500 J/s = 500W
