It is the largest oxygen volume uptake by time unit on breathing atmospheric air during effort, and it is proportional to the product of heart output by the oxygen arteriovenous difference.
These higher anaerobic contributions were accompanied by both greater AOD deficits and larger decreases in oxygen uptake during SCE repetitions.
With these agents there was a large stimulation in oxygen uptake after subsequent addition of DNP, although with resveratrol this did not reach the level seen after oligomycin or quercetin.
When the oxygen uptake is larger than 1.13 mmol/g/h per 1 mmol/g/h of glucose and glycerol, the FBA prediction is that glucose and glycerol will be consumed simultaneously.
If oxygen uptake is larger than 1.96 mmol/g/h per 1 mmol/g/h of glucose, ethanol will no longer be produced, because oxygen is now in excess, and glucose can be completely consumed via respirative pathways (YEtOH/Glu = 0.00 mmol/mmol, Yx/s = 3.97 Cmmol/mmol).
"We had large differences in respiration, in maximum oxygen uptake, in the results of muscle and adipose tissue biopsies," Dr. Bouchard said, referring to changes in endurance and ability to exercise at a high intensity as well as changes in body fat and in the sizes of different types of muscle fibers.
Mucosal permeability may therefore be protected to a large degree, only becoming compromised when oxygen uptake is below 50% of control [ 61].
We used this measure as an indicator of physical fitness because it is easier to incorporate into large cohort studies, compared with maximal oxygen uptake (VO2max) on treadmill or bicycle exercises.
In conclusion, in rowers aged 12 13 year a higher aerobic capacity (as measured by maximal oxygen uptake in L/min), and a larger body size are beneficial for performance over 1000-m rowing ergometer distance.
It has been suggested that the aerobically fuelled muscle mass in some fish is not large enough to force them to reach the maximum rate of oxygen uptake during maximal swimming performance [32].
