    • Glycogen depletion
      • glycogen stores are limited - enough for 90mins
      • when depleted athletes 'hit the wall' as body metabolises fat
    • Dehydration
      • water is lost through sweating - if not replaced dehydration occurs
      • effects blood flow to working muscles
      • result in loss of electrolytes which help muscular contractions
      • blood viscosity increases and blood pressure reduces
    • Reduced rate of ATP resynthesis
      • when stores of ATP and PC are depleted there is insufficient ATP to sustain muscular contractions
    • Thermoregulation
    • Lactic acid build up
