We Built the HIIT Science Taxonomy on Logic. Now We Have the Data. With Dr Martin Buchheit and Prof Paul Laursen

What really happens to your neuromuscular system after different types of HIIT — and how do we know?This episode does something we've been building toward for years: puts real data behind the HIIT Science taxonomy. Using low-frequency fatigue measurements from Myocene technology, Martin Buchheit tested the taxonomy on himself — mapping how different interval types load and recover the neuromuscular system in ways we previously could only infer.The conversation covers why some sessions crush your legs for 48 hours while others don't, why neuromuscular RPE tracks fatigue better than most coaches expect, and why the distinction between load and response still gets muddled in practice.The episode closes with a second topic: how change of direction changes everything in HIIT prescription — and why acceleration and deceleration capacity need to drive individualization in team sport training.In this episode:Why HIIT has always been about more than metabolic zonesLow-frequency fatigue as an objective window into neuromuscular recoveryConcentric vs. eccentric load — why cycling and running recover so differentlyNeuromuscular RPE: cheap, practical, and surprisingly validRethinking COD-based interval prescription for team sport athletesMartin Buchheit's New Course For those interested in going deeper, Martin’s updated course on Load and Response Monitoring in Elite Football is now available inside the HIIT Science course library.It builds on the same ideas discussed here, focusing on how to better connect training load with athlete response using practical frameworks and real world examplesEarly access is currently available for a limited time.
