Study Notes
Muscle Fatigue
- Primary cause of muscle fatigue: accumulation of lactic acid and inorganic phosphates
- Increased acidity: inhibits glycolytic enzymes, reducing energy production
Exercise and Energy Production
- During exercise: glycogen stores are depleted
- Rate of energy production from fat: slower compared to glucose
- Energy from fat: primary source during low-intensity, long-duration activities
Oxygen Debt
- Temporary excess oxygen use after exercise: contributes to excess post-exercise oxygen consumption (EPOC)
- Resolution of oxygen debt: repayment of oxygen deficit through increased oxygen intake
- Primary cause of oxygen debt: imbalance between oxygen demand and supply during exercise
