Mastering Interval Training for Ultrarunners with Michael Rosenblat, PhD #198

Episode overview:

Michael Rosenblat is a researcher and coach with expertise in kinesiology, physiotherapy, and exercise science. In this episode we discuss his three most recent meta-analyses on interval structure, including how to translate cycling intervals to protocols for runners, interval duration and macrostructure, and the relationship between VO2peak and time trial performance.

Episode highlights:

(14:24) Translating interval structure: it depends, direct translation usually works, tendon loading, injury prevention, recovery, metabolic load is probably 1:1

(32:59) HIIT volume: example of 20x1min versus 4x5min, metabolic differences, total session volume does not correlate with improvement, duration of work bout does, maximizing versus optimizing time at intensity

(51:14) VO2max vs. performance: %change in VO2peak does not correlate with %change in performance, Paula Radcliffe example, VO2max plateaus with years of training but performance keeps improving, CTS lab example
