A nutritional intervention for moderate altitude endurance preparation: A case report

Area of Science:

• Sports Nutrition
• Altitude Physiology
• Exercise Metabolism

Background:

• Moderate altitudes induce physiological and metabolic changes impacting exercise performance.
• Nutritional interventions can modulate these altitude-induced adaptations.
• This study presents the first nutritional intervention case for a moderate altitude athlete.

Observation:

• An 11-week nutritional intervention (2800-3500 kcal/day) was applied to a male high-level moderate altitude athlete.
• The intervention included specific macronutrient targets, iron, antioxidants, creatine, and beta-alanine.
• Key metrics monitored included body composition, strength, fitness, nutrient oxidation, and sleep quality.

Findings:

• The athlete exhibited decreased adiposity and increased fat-free mass.
• Muscle strength and endurance adaptations improved, evidenced by enhanced heart rate recovery.
• Carbohydrate oxidation increased during rest and exercise, alongside improved subjective sleep quality.

Implications:

• Nutritional strategies adapted to altitude can optimize body composition in athletes.
• Tailored nutrition enhances physiological adaptations to exercise at moderate altitudes.
• This approach can improve substrate utilization and performance for high-level athletes in hypoxic environments.
