Jem Arnold takes a break from his PhD studies to discuss the implications of a recent meta review and systematic analysis on how training intensity distributions impact VO2max and time trial performance, on which he is a coauthor. We also dig into the methods behind a paper like this, and the statistical distributions of performance itself and how that affects interpretation. We also discuss his doctoral studies on flow limitations in the iliac arteries, the role of NIRS, and long term implications of training with such issues, plus his blog, VO2max training, and more.
