  • how does fuel depletion affect fatigue
    less fuel/slower atp synthesis
  • factors affecting fatugue
    fuel/time/electrolytes/fluid/doms/obla
  • fatigue
    overwhelming sustained feeling of exhaustion and decreased capacity to complete physical and mental work
  • tedium
    vary training to prevent boredom or overuse injury
  • reversibility
    adaptations lost if training stops
  • FITT
    frequency/intensity/time/type
  • progressive overload
    increasing FITT over time to ensure the body is pushed beyond its normal rythm
