Real-Time Microcycle Fatigue & Recovery Curve

7-Day cellular restitution trajectory modeled against throwing volume

Active Fatigue (%)
Tissue Readiness (%)

Valgus Elbow Torque

High velocity throws generate over 80-100 N·m of medial elbow torque. When volume exceeds 100+ pitches, stabilizer tendons rely heavily on rest cycles to avoid micro-tearing.

Ulnar Collateral Ligament load: 88.2 N·m

Age-Related Collagen Elasticity

At advanced ages (>45), collagen turnover slows by ~35%. While veteran neuromuscular efficiency preserves strikeout precision, tendon resilience demands extended rest windows.

Metabolic recovery multiplier: 1.58x

Rest-Window Sufficiency

With 4 rest days completed against 7 recommended, the arm retains residual fatigue. A throwing workout today carries high cellular joint friction.

Current Recovery Deficit: 3 Days Deficit
