Lactate - Friend or Foe Flashcards
Why should lactate be used instead of lactic acid?
- contributes to ongoing confusion regarding energy metabolism and models of muscular fatigue
Is lactate responsible for muscle fatigue?
- NO
What is lactate used for in the body?
Energy Substrate
- metabolism im multiple tissues
Is Lactate confined to anaerobic conditions?
- NO
What might limit the use of a Lactate threshold for individual athletes?
- fidelity of traditional lactate threshold measuring techniques
What was found during moderate intensity exercise with lactate appearance and concentration in excess of endogenous production?
- Increase in lactate oxidation
- decrease in glucose oxidation
What happened with exogenous lactate infusion?
Increased
- lactate into glucose
Decreased
- Glucose from glycogenolysis
Discuss how lactate infusion effected fatigue in exercising men?
- Not associated with increase in sensation of fatigue
What can lactate do for glucose and glycogen in times of increased energy demands?
Spare
- Blood Glucose
- Liver Glycogen
