Core Nutrition Principles for Swimmers

Balanced Plate Rule

  • 1/2 plate fruits & vegetables - vitamins, minerals, antioxidants
  • 1/4 plate protein - chicken, fish, eggs, tofu, beans
  • 1/4 plate whole grains - rice, pasta, potatoes, oats
  • Helathy fats - avocado, nuts, seeds, olive oil

Key Nutrients

  • Carbohydrates: main fuel source for long practices
  • Protein: repairs muscles after training
  • Helthy fats: support growth and sustain energy
  • Calcium & Vitamin D: bone strenth
  • Iron: oxygen transport (especially important for teen girls)
  • Hydration: critical for performance and focus

Fueling for Training

  • Banana with nut butter
  • toast with honey
  • yogurt with berries

Afternoon/evening practice (balanced meal 2 - 3h before)

  • grilled chicken wrap + fruit
  • rice bowl with salmon & veggies
  • turkey sandwich & side salad

During Practice (for 90 minutes session)

  • water for hydration
  • diluted juice for energy

After Practice (within 30-60 minutes)

  • Goal: Carbs + Protein for recovery
  • Examples:
