Formula: Exercise Glycogen Resynthesis Guideline (ACSM)
Carb Grams = (Total Calories × Carb Fraction) / 4Carbohydrate is the primary substrate for high-intensity muscular contractions and liver/muscle glycogen storage.
Model Assumptions
- Sufficient cellular insulin sensitivity
Variables & Standard Units
| Symbol | Physiological Meaning | Unit |
|---|---|---|
| Carb Fraction | Dietary percentage (0.05 to 0.60) | dimensionless |
Scientific Limitations
- Individuals with impaired glucose tolerance may benefit from lower carbohydrate percentages
