Entry #017: Autonomic Regulation and HRV-Guided Training Architecture
The quantification of recovery remains the most elusive variable in endurance periodization. While external load—measured in watts or pace—
Snippet #014: Autonomic Competition at the Sinoatrial Node Drives HRV
The Mechanism
Heart rate variability (HRV) emerges from the dynamic interplay between sympathetic and parasympathetic signaling at the sinoatrial node,
OpenLab #004: Competing at at an Ironman with Type 1 diabetes - Lucas (coachee) - Part II
Welcome back to the second part of OpenLab #004. In Part I, we covered the foundational physiology of glucose regulation
Entry #016: The Science Of Training Periodization in Endurance Sports (Base, Build, Peak, Taper, Transition)
The fundamental challenge in endurance training architecture is managing the non-linear dose-response relationship between training stress and physiological adaptation. While
Snippet #013: Sodium Bicarbonate Facilitates Hydrogen Ion Efflux to Preserve Contractile Function
During intense exertion, hydrogen ions accumulate within muscle fibers, creating an acidic environment that inhibits the enzymes responsible for energy
OpenLab #005: Perceived Effort, Confidence & the Central Governor with Lex
In cycling, the cessation of effort rarely stems from catastrophic muscular failure. Instead, performance limits are frequently dictated by the
Entry #015: The Physiological Necessity of Time Near VO2max (T@VO2max)
In the architecture of endurance performance, a fundamental tension exists between the accumulation of low-intensity volume and the precise application
Snippet #012: Blocking Central Fatigue Signals to Extend Endurance Capacity
The primary driver of caffeine’s performance benefit is not metabolic energy production, but the blockade of adenosine receptors in
OpenLab #004: Competing at an Ironman with Type 1 diabetes - Lucas (coachee) - Part I
Before we kick off today’s OpenLab, I want to express my sincere gratitude to the co-author of this edition,
Entry #014: The use of Finnish and Infrared sauna for recovery and training
This guidance applies to the integration of passive heat therapy—specifically traditional Finnish sauna and infrared sauna—into recovery and
