The energy cost of horizontal running can be estimated accurately because A)the VO₂ of running is always the same. B)the VO₂ of horizontal running is always 1 MET. C)the VO₂ increases linearly with running speed. D)none of the above answers are correct.

Question

Quizplus · Accepted Answer

The energy cost of horizontal running can be estimated accurately because the oxygen consumption (VO2) increases linearly with running speed. This linear relationship allows for predictable calculations of energy expenditure based on speed.
