How does the Physiological Cost Index evaluate energy cost during gait?

Question

Quizplus · Accepted Answer

The Physiological Cost Index (PCI) evaluates energy cost during gait by determining the relative cost of walking per unit of distance walked. It takes into account the oxygen cost of walking and the individual's maximal oxygen uptake, which can then be used to compare the energy cost of walking to normal values. Therefore, option A is the correct answer. Option B is incorrect because the PCI does not evaluate functional muscle strength. Option C is partially correct but lacks the specification of how the energy cost is compared to normal values. Option D is also incorrect as the PCI does not examine the distance walked within a given period of time, but rather the energy expended during gait.
