CanFitPro Personal Training Specialist Practice Test

The development of the central component of VO2max, which includes the cardiovascular and respiratory systems, does not necessarily guarantee improvement in the peripheral component, which includes the muscles and peripheral circulation. While high-intensity training can improve both components, it is possible for one to improve without the other depending on the individual's training regimen and physiological adaptations. Option A and C are incorrect because they suggest a direct and exclusive relationship between the two components, while option D is incorrect because it implies that there is never any interaction between the central and peripheral components. Therefore, option B is the best answer as it acknowledges that the development of one component does not necessarily lead to improvement in the other.
