Examiners report
This is a contextual question that candidates found challenging. Candidates are not expected to know specific percentages, but they need to have an appreciation of the size of difference between the modes of exercise. Most candidates selected D and therefore understood that arm ergometry has a lower value compared to treadmill running but were unable to distinguish between the size of the difference. This was expected to be a challenging question, but these types of contextual questions are to be included in the future papers. G2 form comments were raised regarding the language used for these questions and this will be taken on board for future papers.
