  • Hydration
    • all levels of dehydration decrease performance
      • as dehydration increases so do the negative effects
    • losing 2% of body weight in sweat can cause up to 20% decrease in performance due to:
      • decreased heat regulation and increased temperature
      • increased blood viscosity
      • increased heart rate
      • increased fatigue
      • Untitled
    • the loss of electrolytes (salts and minerals that can conduct electrical impulses) through sweat can also cause fatigue and cramping
    • an athlete should be well hydrated prior to training or performance and replace all lost fluids throughout the performance
    • For every 1kg of body mass lost during the activity, 1 litre of fluid should be more consumed
