Sample Answer
- Sprinter requires higher protein intake (2.0g/kg) for power/strength maintenance while marathon runners need moderate amounts (1.2-1.4g/kg)
- Marathon runner needs greater carbohydrate stores (7-10g/kg) compared to sprinter’s moderate requirements (5-7g/kg)
- Sprinter focuses on creatine supplementation to enhance ATP-PCr system while marathon runner emphasises electrolyte balance
- Marathon runner emphasises pre-race glycogen loading while sprinter maintains normal carbohydrate intake
- Timing of intake varies based on event duration with sprinters eating 2-3 hours pre-event versus marathon carb-loading days before
