You are advising an athlete who will compete in an 800-meter race (approximately 1.5–2 minutes). Which pre-event nutritional and training strategy best synthesizes knowledge of energy systems to optimize performance?

Emphasize high-fat, low-carbohydrate meals immediately before the race to train the body to use fat for high-intensity bursts and avoid any interval training which would favor aerobic development only.

Consume only protein before the race to build muscle on race day and rely on the ATP–CP system alone during the event since protein directly fuels creatine phosphate regeneration.

Avoid all fueling and training adaptations related to anaerobic systems; rely on slow long-distance training to make the aerobic system the exclusive source of ATP during the race.

Prioritize carbohydrate-rich glycogen stores through targeted carbohydrate intake in the 24–48 hours before the race and maintain training that develops anaerobic capacity (intervals) and creatine phosphate buffering to support high-intensity efforts lasting ~1–2 minutes.
