Functional threshold power and the (manufactured) critical power controversy

Research output: Contribution to journalArticlespeer-review


We read with concern yet another communication from Dotan regarding the critical power (CP) concept which contains a litany of factual errors, false statements, and dated physiological interpretations. Space does not permit us to rebut every incorrect point made about our work (Wong et al., 2022) and the wider field in which it sits, but we will address what we consider to be some of the more egregious errors in his letter. We would first note, however, that our paper was not actually focused on the critical power concept. Copyright © 2023 Informa UK Limited, trading as Taylor & Francis Group.
