This is a quick transfer of a massive twitter thread I posted in June, 2023. Since Txitter is more difficult to read these days without an account, and even less worth it than ever to create an account.. I will try to transfer some threads back to here. This is basically just an archive of … Continue reading Cadence Affects Everything, and it Doesn’t Really Matter
A meta-analysis on endurance athletes' training found that while high-intensity interval training (HIIT) above the maximal metabolic steady state (MMSS) significantly improved oxygen uptake (V̇O2peak), there was no detectable difference in time-trial (TT) performance. This suggests that although increased V̇O2peak is achievable through HIIT, translating it into enhanced TT performance may require a different approach or potentially longer timeframes. The findings may inform athletes on balancing low/intermediate intensity and HIIT sessions.
Oxygenation Response Profiles represent the SmO2 trend as a function of progressive exercise intensity measured at the vastus lateralis. Two general profiles have been observed that may reveal some so-far unexplained, but apparently systematic physiological variance between subjects of differing fitness and muscle tissue typology. Unexplained variation means we still have something to learn about human physiological response to exercise.
We recently published an article comparing the NIRS-derived deoxy-BP to the RCP (VT2) in a ramp cycling test. I want to use this and another similar study to understand the important differences between threshold measurements, the natural variability in measuring physiology, and how understanding this variability can help us prescribe training targets that will elicit the desired training stimulus for ourselves and our athletes.
This is a basic template for what I currently consider to be a solid, simple, sustainable training plan that can be individualised, modified, mixed around, and repeated near ad infinitum. This can be used as a foundation for whatever training goals we have, be they focused on performance with a specific peak event/race date in mind, or more about sustaining general health, fitness, longevity, and resiliency.
