Sample Answer
Similarities:
- Both athletes require:
-
- The equivalent carbohydrate intake in the hours before competition.
- Protein for muscle repair and recovery.
- Planned nutrition timing to optimise performance.
- Adequate hydration before competing.
Differences:
- Marathon runners require low glycaemic index carbohydrates for sustained energy while sprinters need high glycaemic index carbohydrates for quick energy.
- Marathon runners need significantly higher daily carbohydrate intake plus loading protocols, whereas sprinters require moderate amounts without loading.
- Marathon runners must consume carbohydrates during events for sustained energy, while sprinters only need pre-event intake.
- Sprinters require more protein for explosive muscle damage repair than marathon runners.
- Marathon runners need continuous hydration with electrolytes throughout events, while sprinters focus on pre-event hydration status.
