Crossfit model of fitness #3: Metabolic Pathways
Phosphagen Pathway
- Also called the phosphocreatine pathway
- Can produce 100% of maximum power
- Lasts about 10 seconds — e.g., 100-meter sprint
Glycolytic Pathway
- Also called the lactate pathway
- Can produce approximately 70% of maximum power
- Lasts about 2 minutes, peaking at approximately 60 seconds — e.g., 400-meter sprint
Oxidative pathway
- Also called the aerobic pathway
- Can produce approximately 40% of maximum power
- Sustainable until the anaerobic threshold is crossed — e.g., a 10,000-meter run
The fittest person will have the best balance of capacity across all pathways, and a fitness program should develop your capacity in each.
