Young athletes have unique nutritional needs due to physiological differences. This review covers energy requirements, carbohydrate intake effects on performance, and dehydration prevention strategies for children in sports.

Area of Science:

  • Sports Nutrition
  • Pediatric Exercise Physiology
  • Nutritional Science

Background:

  • Children athletes exhibit distinct physiological traits compared to adults.
  • These differences necessitate tailored nutritional strategies for optimal health and performance.
  • Key distinctions include higher protein and calcium needs, increased locomotion energy costs, and altered sweat/thermoregulation responses.

Purpose of the Study:

  • To review the specific nutritional considerations for young athletes.
  • To examine the impact of carbohydrate ingestion on pediatric exercise.
  • To address hydration challenges and prevention in child athletes.

Main Methods:

  • Literature review focusing on pediatric exercise science and sports nutrition.
  • Analysis of studies on energy metabolism, substrate utilization, and thermoregulation in children.

  • Synthesis of research on hydration and carbohydrate supplementation effects.

    • Main Results:

    • Children have a higher metabolic cost for locomotion, impacting daily energy needs.
    • Carbohydrate ingestion (glucose, fructose, sucrose) influences aerobic performance, substrate use, and immune responses in young athletes.
    • Children experience greater thermoregulatory strain and involuntary dehydration during exercise in heat.

    Conclusions:

    • Specific nutritional strategies are crucial for young athletes' growth, bone health, and performance.
    • Understanding carbohydrate metabolism and hydration is vital for preventing adverse effects.
    • Further research is needed to optimize nutritional guidelines for pediatric sports participants.
