Quizplus · Accepted Answer

Poor running economy means that a runner requires more oxygen consumption (V̇O2) to maintain a certain running speed. This leads to a higher V̇O2 at any given running speed compared to an economical runner, hence higher V̇O2max (which is the highest rate of oxygen consumption that an individual can achieve) and V̇O2 at lactate threshold (which is the point where lactic acid starts accumulating in the muscles). Therefore, the answer is B - a runner who exhibits poor running economy requires a higher V̇O2 at any given running speed compared to an economical runner.
