Discussion: "The efficacy of the self-paced VO_2max test to measure maximal oxygen uptake in treadmill running"

Abstract

We wish to raise some concerns about the above study published on-line in Applied Physiology, Nutrition and Metabolism. Most important is the issue of biased reporting as the authors have failed to acknowledge the findings of a critical paper by Chidnok et al 2013 (first published on-line in the European Journal of Applied Physiology in Sept 2012) which provided a rigorous and comprehensive assessment of a self-paced (RPE-guided) test versus two conventional ramp incremental protocols.
