Sample Answer
- B vitamins crucial for ATP production: B1 and B2 needed 50% higher in aerobic athletes for sustained energy metabolism
- Iron requirements 30-50% higher in aerobic athletes due to increased red blood cell production and oxygen transport
- Zinc particularly important for anaerobic athletes as it aids protein synthesis and muscle repair post high-intensity effort
- Magnesium requirements increase 20% in both systems: aerobic athletes need it for endurance muscle contraction while anaerobic athletes require it for explosive force production
