Document Summary

Short swimming events, 15% comes from aerobic metabolism. V02 = o2 inspired o2 expired: so when we measure at the mouth it reflects the muscle. Inspired air minus expired air: need to know the volume coming in and the fraction of it that is oxygen, 20. 93% of the air we breathe has oxygen in it. Volume of the air moving in and out can be different. Carbon dioxide production: co2 expired co2 inspired. Basal metabolic rate: the minimal energy needed to maintain body function, represented by a metabolic equivalent (met) = 3. 5ml/kg/min o2. If we look at o2 consumption (reflects how much atp is being produced aerobically) What can u do with this information: you can come up with our bmr. 80kg x 3. 5ml = 0. 280lo2 x 60 mins = 16. 68 lo2/h. X 24hours = 403. 2 l x 4. 8 kcals/lo2 = 1935 kcals.
