Evolution of Maximal Oxygen Uptake in Children

2007
Evidence exists that physiologic aerobic fitness, defined by maximal oxygen uptake related to body mass (VO2 x kg-1), bears health implications for children as well as adults. Identifying secular trends in VO2max x kg-1 is important, then, in assessing the impact of socio-cultural influences on aerobic fitness in youth.

A maximal cycle exercise protocol to predict maximal oxygen uptake

Scandinavian Journal of Medicine & Science in Sports, 1995
Maximal oxygen uptake (VO2max) was predicted from maximal power output (MPO) in a progressive cycle ergometer test. The subjects were 232 men and 303 women 15–28 years of age. The relationship between VO2max and MPO was: V O2max (1 · min−1) = 0.16 + (0.0117 × MPO) (w). A correlation coefficient of r= 0.88 was found between MPO and VO2max.

Mean myoglobin oxygen tension during exercise at maximal oxygen uptake

Journal of Applied Physiology, 1975
Changes in intracellular Po2 in myoglobin containing skeletal muscle during exercise were estimated in normal nonathlete subjects from measurements of shifts of CO between blood and muscle under conditions where the total body CO stores remained constant. Exercise was performed on a bicycle ergometer.

Sex difference in maximal oxygen uptake

European Journal of Applied Physiology and Occupational Physiology, 1986
Ten men and 11 women were studied to determine the effect of experimentally equating haemoglobin concentration ([Hb]) on the sex difference in maximal oxygen uptake (VO2max). VO2max was measured on a cycle ergometer using a continuous, load-incremented protocol.

Maximal oxygen uptake "classical" versus "contemporary" viewpoints

Medicine & Science in Sports & Exercise, 2000
In two articles Timothy Noakes proposes a new physiological model in which skeletal muscle recruitment is regulated by a central "govenor," specifically to prevent the development of a progressive myocardial ischemia that would precede the development of skeletal muscle anaerobiosis during maximal exercise.

Factors limiting maximal oxygen uptake in exertional monoparesis

Multiple Sclerosis Journal, 2005
Strength and maximal oxygen uptake (VO2max) for each leg were compared in a trained multiple sclerosis (MS) patient with exertional left monoparesis. Left quadriceps strength and left leg VO2max were 22% and 30% lower, respectively, compared to the right (control) leg.

Limitations to maximal oxygen uptake.

Sports medicine (Auckland, N.Z.), 1992
An increase in exercise capacity depends on the magnitude of increase in maximum aerobic capacity. Central and peripheral factors may limit oxygen uptake. Central oxygen delivery depends on cardiac output and maximal arterial oxygen content. Peripheral extraction of the delivered oxygen is expressed as a-v O2.

[Oxygen uptake and maximal oxygen uptake: interests and limits of their measurements].

Annales de readaptation et de medecine physique : revue scientifique de la Societe francaise de reeducation fonctionnelle de readaptation et de medecine physique, 2004
The paper presents a review of the interests and limits of oxygen uptake measurement in the functional testing of athletes and disabled people. The validity of the oxygen uptake as an estimation of the oxygen consumption and aerobic synthesis of ATP is discussed in the introduction of the review.
