Three Training Principles That Always Matter
Adaptation, progressive overload, specificity. These three principles underpin every training decision we make — and every piece in this series builds on them.

Training vs. Exercise: The Five Variables That Make the Difference
Frequency, intensity, timing, tempo, and volume are not concepts — they are the tools of structured programming. Understanding them is what separates deliberate training from exercise.

Why "Tennis Wrist" Isn't About How Much You Play
The injury that cost Alcaraz an entire season isn't caused by volume. It's caused by what the wrist is doing during each swing — and the two fault patterns that produce it.

Why We Design Programs
The fitness-fatigue model, periodization, and why a well-structured program looks nothing like hard work on a Tuesday in February — but produces it in August.

The LTAD Model, Part 1: Building the Athlete Before You Build the Player
Coordination, suppleness, and movement culture come before technique — and rushing that sequence is exactly what builds the habits you spend years afterward trying to unwind.

The LTAD Model, Part 2: Why Competitive Density Has to Match the Stage
The adult tour model is not a scaled-down template for ten-year-olds. How competition load, scheduling, and tournament density should actually look at each developmental stage.

There Is No "Optimal" Contact Point — There's Yours
Grip, anthropometrics, stroke mechanics, and surface set your personal default. Rise vs. fall is a live tactical decision on top of that. "Top of the bounce" is neither.

Forged, Not Found: The Neuroscience of Mental Toughness
Mental toughness is not a personality trait — it is a trainable neural adaptation. The same biological mechanism that governs physical supercompensation governs the aMCC. The implications for program design are significant.

The Energy Map: Metabolism Foundations
ATP, PCr, glycolysis, oxidative phosphorylation — not as isolated systems but as a single, continuously shifting energy continuum. Understanding which pathway dominates at any moment changes how you train, taper, and fuel.

The Protein Issue: Structure, Synthesis, and What Timing Does
Protein is not just building material — it is a signaling molecule. Leucine thresholds, the muscle-full effect, the refractory window: the science of when and how much matters as much as total daily intake.

Creatine — The Phosphocreatine System, Expanded
PCr resynthesis kinetics, loading protocols, the cognitive benefit window, and the tennis-specific case for supplementation. The most evidence-backed ergogenic aid in sport, examined in full.

Glycolytic Buffering — Beta-Alanine, Bicarbonate, and pH
Hydrogen ion accumulation is what ends the point, not lactate. Beta-alanine, sodium bicarbonate, and the buffering cascade that determines how long a player can sustain high-intensity output before the system breaks.

Caffeine and the Science of Fatigue Perception
Caffeine does not create energy — it blocks the signal that you're running out of it. Adenosine antagonism, the habituation debate, genotype-dependent response, and the real-world case for strategic use across a tennis season.

NO & Endothelial Function — Citrulline and the Vascular Side of Performance
Why L-arginine fails as a supplement, how citrulline bypasses first-pass catabolism via the kidney, the separate dietary nitrate/beetroot pathway, and what the performance evidence actually shows for tennis-relevant high-intensity and intermittent protocols.
