Data shows that hypoxic training does result in increased oxygen uptake and better performance.However,what makes these studies hard to interpret?

Question

Quizplus · Accepted Answer

The studies on hypoxic training are difficult to interpret because of both a lack of a suitable control group and because training of any kind will result in increases in performance, so it is hard to make correlations between hypoxic training specifically and the observed improvements in performance. Option A, B, and C are incorrect because they do not give both reasons for why the studies are hard to interpret. Therefore, the correct answer is D.
