Carbohydrates (Carbs):

  • Main source of energy for the body, muscles and brain.
  • General recommendation: 45% -65% of daily energy intake.
  • Recommendation for athletes: 3-10gr/kg of Body Weight/day (nearly nonexistent for young athletes).
  • Low carbs diet: Early fatigue and muscle breakdown to provide energy (faster fatigue in young athletes due to reduced glycogen stores).
  • Carbs during exercise (> 60mins): Important for maintain blood glucose.
  • Carbs immediately after exercise (30-60mins): Important for improve muscle glycogen storage.

Good sources of Carbs:

Pasta, rice, bread, cereals, quinoa, oats, legumes, fruits, vegetables and starchy vegetables (such as corn, zucchini, sweet potatoes, potatoes).

Micronutrients (vitamins, trace elements, minerals):

Although there are many vitamins and minerals required for good health, particular attention should be devoted to ensuring that young athletes consume proper amounts of calcium, vitamin D and iron.

Calcium - Ca (1):

  • Important for bone health, normal enzyme activity and muscle contraction
  • Daily recommended intake (DRI) for athletes 4-8 years: 1000mg/d
  • DRI for athletes 9-18 years: 1300mg/d

Vitamin D – VitD (2):

  • Necessary for bone health and involve the absorption and regulation of Ca.
  • DRI for athletes 4-18 years: 600 ΙU/d (depends on geographical location & race).

Iron - Fe (3):

  • Important for oxygen delivery to body tissues.
  • Increased needs during adolescence: Rapid growth and increase in blood volume and lean muscle mass.
  • DRI for athletes 9-13 years: 8 mg/d
  • DRI for athletes 14-18 years: Boys 11 mg/d, Girls 15 mg/d (due to menstruation).
