Central Governor Theory: Why Your Brain Shuts You Down Before Your Muscles Fail
The central governor theory explains why your brain shuts you down before your muscles actually fail. Here’s the mechanism and what it means for performance.
Glycogen Depletion: What Actually Happens When Carbs Run Low
Glycogen depletion is a rate problem, not a supply problem. Fat stores are massive, but the constraint is how fast fat can deliver ATP at high intensity.
The Fitness-Fatigue Model: What Durability Actually Means in Performance
Home / 01 — THE WRONG STANDARD The Wrong Standard for Performance Performance, as most athletes track it, is a
Mitochondrial Density and Performance Capacity
Mitochondrial density in skeletal muscle is the real ceiling on sustained aerobic performance. Learn how it works, what builds it, and why it matters.
How Much Sleep Do Athletes Need?
Understand how much sleep do athletes need and why. Covers GH secretion, glycogen resynthesis, motor consolidation, and HPA axis effects on recovery.
Peak Intensity Performance Basics: The Anaerobic Energy System
How the anaerobic energy system powers peak intensity, why fatigue is a cellular chemistry event, and what this means for repeatable high-intensity output.
What Is Cardiac Output and Why It Determines Sustained Performance
What is cardiac output? It sets the ceiling on aerobic performance. This article explains stroke volume, cardiovascular drift, and cardiac training adaptation.
Glycogen Depletion: The Hidden Limiter
Glycogen depletion is the hard ceiling on high-intensity work. Understand the mechanism behind the bonk, why it goes undetected, and what it means for training.
Oxygen Delivery vs. Aerobic Conditioning: Why They’re Not the Same
Oxygen delivery and aerobic conditioning are not the same physiological system. This article explains the difference and what it means for athletic training.
Average VO2 Max by Age: What Your Number Actually Means (And What It Doesn’t)
Average VO2 Max by age marks your aerobic ceiling. But the ceiling is rarely what limits performance. Here is what the three performance variables actually are.
