Does High Intensity Training Improve Performance or only VO2max?

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.

Study Summary – Reliability of Common Cycling Performance Markers

Here is a brief summary of our recent paper from the University of British Columbia Environmental Physiology Laboratory authored by my colleague Dr. Assaf Yogev and our colleagues. We think this is a paper that athletes & coaches can use to help understand uncertainty in performance data collection. The results here can be used as … Continue reading Study Summary – Reliability of Common Cycling Performance Markers →

Thresholds, Constructs, and Confidence Intervals

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.
