Lactate Threshold
Lactate Threshold
The point during exercise at which lactate builds up in the blood faster than it can be removed.

Study Notes
Mitochondrial Hydrogen Shuttle System and Lactate Production
- Figure 4.9 illustrates the mitochondrial hydrogen shuttle system.
Practical Uses of Lactate Threshold
- Lactate threshold prediction can be used to predict endurance performance (e.g., 10K).
- It's combined with running economy.
- Lactate threshold helps in planning training programs.
- It serves as a marker of training intensity.
- Training heart rate can be selected based on the lactate threshold.
- Training near (but slightly below) the lactate threshold is effective in shifting the lactate threshold to a higher intensity.
