Sample Answer
Allows targeted fuelling strategies:
- Aerobic activities, like distance running, require regular carbohydrate intake during performance → 60-90 grams carbohydrate/hour.
- Anaerobic activities, like sprinting, focus on pre-activity carbohydrate consumption to ensure energy availability.
Optimises recovery timing by understanding when different nutrients are needed:
- High carbohydrate foods help replenish energy stores after aerobic activities.
- Protein-rich foods support muscle repair after anaerobic efforts.
Enhances daily nutrition planning through understanding which macronutrients are most important:
- Aerobic athletes need higher carbohydrate intake for sustained energy → 65% carbohydrates.
- Anaerobic athletes require moderate carbohydrate with higher protein → 40% carbohydrates.
Prevents nutritional deficiencies by identifying specific needs:
- Aerobic athletes need increased iron intake for oxygen transport (30% higher).
- Anaerobic athletes require adequate B vitamins and zinc for immediate energy production.
Maximises energy availability by timing nutrient intake appropriately:
- Aerobic athletes need regular meals throughout the day.
- Anaerobic athletes focus on pre and post activity nutrition timing.
