Fatigue

• Types of anaerobic fatigue?

  Depletion of fuels

  • PC Stores -> Glycogen (slower)

  Metabolic By-Products

  • ADP + Pi
  • H+ ions
  • Lactate
• Types of aerobic fatigue?

  Depletion of fuels

  • Glycogen -> fats (slower)

  Increase Temperature

  • blood to skin -> sweat -> water loss

  = thick blood + high BP + lose electrolytes + dehydration

  
  

  Decreased CNS firing

  • To reduce fatigue
• Template for fatigue questions?

  1. Physiological change
  2. Physiological impact
  3. Impact on performance
• What does ADP+Pi do?

  Decrease muscle contractile force -> decreased performance
• What does H+ ion build up do?

  Decrease pH of muscle cells -> denaturation of glycemic enzymes thus decreased muscle contractile force -> decreased performance
• Benefits of Active Recovery?

  • Remove metabolic byproducts
  • Prevent venous pooling
  • Allow for easier thermoregulation (cooling)
  • Allow for more oxygen to be pumped into the muscle
• Benefits of Passive Recovery?

  • Replenishment of PC Stores
