Discuss the macronutrient requirements for power, endurance and strength-training sports. Illustrate with an example.

1. 1 · Open in two lines. Macronutrient needs follow the sport's energy system and the training load. Carbohydrate and protein are set in g/kg; fat fills the rest.
2. 2 · Draw a sport-type table. [Table: endurance, strength/power, combined, skill-based against carbohydrate g/kg, protein g/kg, fat %]
3. 3 · Endurance sports.
   • Carbohydrate 6-10 (8-12) g/kg; loading for races over 90 minutes.
   • Protein 1.2-2.0 g/kg; fluids and iron.
4. 4 · Strength and power sports.
   • Carbohydrate about 4-7 g/kg (Slater & Phillips, 2011).
   • Protein 1.2-2.0 g/kg, often the upper part, in 0.3 g/kg doses; creatine stores; energy surplus for gains.
5. 5 · Combined sports. Hockey, kabaddi, badminton: carbohydrate 5-7 g/kg on moderate days, more on heavy days; recovery between matches.
6. 6 · Worked example. 70 kg hockey player, 3500 kcal: carbohydrate 490 g (56%), protein 112 g (12.8%), fat about 121 g (31.2%).
7. 7 · Nutrition link. Same hostel menu, different cereal and protein portions for each athlete.
8. 8 · Close in one line. Matching each nutrient to the sport and the load is the core skill of sports dietetics.

Scoring tip: A short worked example with a check line (percentages add to 100) lifts a theory answer into the top band.
