Week 26 is your final assessment week. The DCOA Month 6 assessment and SCS rescan measure what 26 weeks of consistent action have produced. Here's the science of what you've built.
These actions target specific biological mechanisms relevant to football performance and recovery. Below: what the research shows and why it matters.
The final week of DēsAL™ is a measurement and integration week — not a new action week. Here's the biology of what 26 weeks of multi-pillar behavior change has produced.
The Compounding Systems Effect. DēsAL™ is built on the principle that small, distributed improvements across six biological systems produce change that single-domain interventions cannot achieve. The six pillars target different but interconnected regulatory systems: inflammation (Diet), mitochondrial function (Exercise), HPA axis restoration (Sleep), autonomic balance (Integrity), cortisol modulation (Gratitude), and attention restoration (Nature). When all six are improved simultaneously, regulatory cross-talk produces synergistic effects that are not predictable from any individual pillar's effect alone. This is the Compounding Systems Effect.1
What the SCS rescan measures. The Prysm iO Skin Carotenoid Score reflects carotenoid status in skin tissue — a cumulative marker of antioxidant intake over 4–8 weeks. A meaningful increase in SCS over 26 weeks indicates genuine, sustained dietary improvement that has accumulated in body tissue — not just occasional healthy meals. The Hester et al. 2026 RCT showed a 41% SCS increase over 12 weeks with the full supplement protocol; dietary change alone produces a smaller but real increase for athletes who have implemented the Diet pillar consistently.2
The DCOA as a behavior change marker. The DCOA (DēsAL Comprehensive Outcome Assessment) measures self-reported function across all six pillar domains. Research on similar multi-domain self-assessment tools shows that 20+ weeks of structured behavior change in athlete populations produces typical effect sizes of 0.4–0.8 standard deviations — moderate to large effects that are meaningful for health and performance. Your Week 26 DCOA, compared to your Week 1 baseline, is the most direct measure of program effect available.3
What 26 weeks builds. If you've implemented the program with reasonable consistency, by Week 26 you have: improved mitochondrial density (Exercise); lower systemic inflammation (Diet + Omega-3 + Olive oil); better circadian alignment (Sleep); a trained pause response under pressure (Integrity); a cultivated gratitude orientation (Gratitude); and regular access to nature's neurological benefits (Nature). These are not temporary states — they are structural changes in physiology, neurobiology, and behavior that persist and compound beyond the program.
