Calibrated Baseline Reference Matrix

Baseline Cohort Muscle CSA (cm²) Hemoglobin (g/dL) Stroke Vol (mL) Est. GRF (N) VO2 Max (ml/kg/min)
Male Elite (Sprinter/Mid-Dist) 100.0 15.2 160 2,450 N 71.7 ml/kg/min
Female Elite (Sprinter/Mid-Dist) 72.0 13.4 125 1,764 N 61.2 ml/kg/min
Sub-Elite / Amateur Average 65.0 14.0 105 1,592 N 49.0 ml/kg/min
Sports Science Governing Equations:
• Muscle Force (F_m) = CSA (cm²) × Specific Tension (30 N/cm²)
• Knee Joint Torque (τ) = F_m × Moment Arm (r_ins)
• Ground Reaction Force (GRF) = τ / (Femur Length × sin(knee_angle))
• Oxygen Transport Capacity (CaO2) = Hb × 1.34 × 0.98 + (PaO2 × 0.0031) ≈ [Hb × 1.34 × 0.98] (ml O2/L)
• Absolute VO2 Max = Cardiac Output (Q_max = SV × HR) × (CaO2 - CvO2)
