Quand demander une VO2 max ?

Revue des Maladies Respiratoires Actualités, 2017
Resume La chirurgie de resection pulmonaire demeure la meilleure option therapeutique dans les stades precoces du cancer bronchique non a petites cellules. Mais cette chirurgie est associee a une morbidite significative notamment chez les patients ayant une fonction pulmonaire ou une aptitude cardio-respiratoire alteree. Pour minimiser ces risques, l’

Validity and reliability of VO2-max testing in persons with Parkinson's disease

Parkinsonism & Related Disorders, 2023
Direct whole body assessment of maximal oxygen consumption (VO2-max test) is considered the gold standard when assessing cardiorespiratory fitness (VO2-max) in healthy people. VO2-max is also an important health and performance indicator for persons with Parkinson's disease (pwPD) and is often used when prescribing exercise and evaluating aerobic ...

Effects of incomplete pulmonary gas exchange on VO2 max

Journal of Applied Physiology, 1989
Recent evidence suggests that heavy exercise may lower the percentage of O2 bound to hemoglobin (%SaO2) by greater than or equal to 5% below resting values in some highly trained endurance athletes. We tested the hypothesis that pulmonary gas exchange limitations may restrict VO2max in highly trained athletes who exhibit exercise-induced hypoxemia ...

Effects of oxone inhalation on work performance and VO2 max

Journal of Applied Physiology, 1979
Ozone (O3) at near ambient smog alert levels has previously been shown to cause alterations in pulmonary function and exercise response in humans. The present study was designed to investigate the effects of O3 administered during graded bicycle exercise to volitional fatigue on work performance and maximal oxygen uptake (VO2max).

Algebraic analysis of the determinants of V̇O2,max

Respiration Physiology, 1993
Considerable evidence exists to support the idea that maximum oxygen consumption in exercising mammals is determined by the quantitative interaction between diffusive and convective factors involved in the transport of oxygen between the environment and the muscle mitochondria.

Field estimation of Vo2 max in children eight years of age

Medicine & Science in Sports & Exercise, 1977
The purpose of the investigation was to explore the validity of using timed distance runs as predictorr of cardiorespiratory fitness in young untrained children. Maximal oxygen consumption and performance in runs of 549, 1207, and 1609 meters (600 yards, 3/4 mile, and 1 mile) were compared in 38 children eight years of age.

Influence of simulated microgravity on the VO2 max of nontrained and trained rats

Journal of Applied Physiology, 1993
Head-down suspension (HDS) of rats has evolved as a useful model for the simulation of a microgravity environment. Previous HDS experiments with rats have shown an impaired capacity to perform aerobic exercise as demonstrated by reductions in maximum oxygen consumption (VO2 max), treadmill run time (RT), and mechanical efficiency (ME) of treadmill ...

Role of muscle loss in the age-associated reduction in VO2 max

Journal of Applied Physiology, 1988
A progressive decline in maximal O2 consumption (VO2max) expressed traditionally as per kilogram body weight generally occurs with advancing age. To investigate the extent to which this decline could be attributable to the age-associated loss of metabolically active tissue, i.e., muscle, we measured 24-h urinary creatinine excretion, an index of ...
