The maximum rate of O2uptake (VO2max) assesses the integrated functioning of the pulmonary, cardiovascular, and muscle systems to:
Uptake O2 (diffusive O2 transport at the lung and muscle microvasculature)
Transport O2 (conductive O2 transport)
Utilize O2 predominantly in the contracting muscle mitochondria
All options (combination of A, B, and C) are correct
The foundational premise of VO2max, dating back at least to the 1920s, argues that:
There exists a speed of locomotion or rate of work above which VO2 fails to increase further
There exists a speed of locomotion or rate of work below which VO2 fails to increase further
There is not exist a speed of locomotion or rate of work below which VO2 fails to increase further
All options (combination of A, B, and C) are correct
The development of rapid-response gas analyzers, enabling measurement of breath-by-breath pulmonary gas exchange, has facilitated
The advent of modern discontinuous progressive maximal exercise tests, which are laborious but not time-consuming
The replacement of the discontinuous progressive maximal exercise test with the rapidly incremented or ramp testing protocol
The replacement of rapidly incremented or ramp testing protocol with the discontinuous progressive maximal exercise test
All options (combination of A, B, and C) are correct
The maximal incremental or ramp testing protocol is suitable for clinical and experimental investigations but does not enable the measurement of:
The gas exchange threshold (i.e., GET)
The exercise efficiency
The VO2 kinetics
The critical power/velocity
The maximal incremental or ramp testing protocol often fails to produce a discernible VO2 plateau or leveling off even when the actual VO2max is, in fact, achieved. This situation is particularly accentuated in:
Moderately-trained athletes
Highly-trained athletes
Extremely unfit subjects
All options (combination of A, B, and C) are correct
A V̇o2-work rate plateau is not an obligatory outcome in a rapidly incremented or ramp testing protocol. The so-called secondary criteria, therefore, emerged and involved:
The respiratory exchange ratio
The maximal heart rate
The maximal power output
All options (combination of A, B, and C) are correct
The inclusion of a short constant test completed at a higher work rate than that achieved during a previous ramp test is important to:
Enable the verification of the VO2 max
Determine the maximal power output
Estimate maximal heart rate
All options (combination of A, B, and C) are correct
The anaerobic threshold (AT) is a widely recognized concept in exercise physiology indicated by:
An increased blood lactate concentration during a progressive exercise test combined with an excess pulmonary carbon dioxide output (VCO2) and muscle anoxia (insufficient O2)
An increased blood lactate concentration during a progressive exercise test combined with an excess pulmonary carbon dioxide output (VCO2) but without the presence of muscle anoxia
An increased blood lactate concentration during a progressive exercise test combined with a decreased lactate release and uptake
All options (combination of A, B, and C) are correct
A. V. Hill (1886-1977) first coined the term "maximal oxygen uptake" and postulated that :
There is an upper limit to oxygen uptake
There are limited interindividual differences in V̇O2max
A high V̇O2max is not a prerequisite for success in middle- and long-distance running
All options (combination of A, B, and C) are correct
The "threshold" concepts in exercise science are important to:
Predict athletic performance
Monitor training progress
Assess therapeutic efficacy
All options (combination of A, B, and C) are correct
