6.5 Performance Boundary Index
Human Fat-Based Metabolism
This page is structured as definition, control variables, causal chain, observable outputs, and boundary, and serves as a canonical definition node in Human FBM.
Different exercise types require different substrate architectures; low-intensity long-duration activity aligns more with fatty-acid fueling.
High-intensity explosive demand relates to glycolytic requirement, and Human FBM does not deny glycogen need in specific scenarios.
Exercise type, intensity, duration, and frequency determine substrate-demand architecture.
Total energy, electrolytes, and recovery state determine performance stability.
Insulin occupancy and fatty-acid fueling capacity shape long-duration endurance baseline.
Training phase and adaptation state determine how short-term performance volatility is interpreted.
Low-intensity sustained activity outputs are more consistent with fatty-acid fueling architecture.
High-intensity explosive demand should be judged within sport-nutrition and specialized-training boundaries.
Under stable structure, low-to-moderate intensity tolerance often improves and recovery quality becomes more stable.
At competitive high-intensity demand, performance must be interpreted through specialized protocols, not generic fatty-acid pages.
Extreme competitive training enters specialized sport-nutrition boundary and is outside generic Human FBM execution pages.
This page is for performance backtrace and provides no training prescription.
