Lactate: Fuel, Not Enemy
- Lactate is not the cause of fatigue but a fuel and useful marker of exercise intensity.
- Blood lactate measurement is popular because it is easy and correlates with fatigue-related biochemical changes.
Lactate Threshold Variability
- Lactate threshold varies abundantly among individuals from about 2 to 7 mmol.
- The commonly cited 4 mmol value is unreliable and varies by day and conditions.
Lactate Shuttle System Explained
- Lactate is produced from pyruvate and can be either utilized locally or shuttled through the blood to other muscles or organs.
- The lactate shuttle acts like a transport system for fuel distribution and usage.
