Sample Answer
Similarities:
All sporting activities require:
- Carbohydrate intake as the primary fuel source for movement.
- Appropriate timing of consumption for optimal performance.
- Post-exercise carbohydrate intake for recovery.
- Adjustment of intake based on training intensity and duration.
Differences:
- Endurance sports require significantly higher daily carbohydrate intake while power sports need moderate amounts.
- Aerobic activities benefit from low glycaemic index carbohydrates for sustained energy whereas anaerobic sports use high GI for rapid glucose availability.
- Marathon runners need carbohydrate loading protocols before events while sprinters require only normal intake.
- Endurance athletes consume carbohydrates during prolonged events whereas power athletes only need pre-event fuelling.
- Recovery demands differ with endurance athletes requiring more frequent glycogen replenishment than power athletes due to greater depletion.
Sport-Specific Application:
- The role of carbohydrates fundamentally differs based on energy system demands. Aerobic sports require sustained availability while anaerobic sports need immediate accessibility.
