Nutrition: your invisible fuel

A judoka can train 20 hours a week, but if their nutrition doesn't follow, performance will suffer. Nutrition is particularly critical around competitions.

Before competition

The week before

  • Increase complex carbs: rice, pasta, sweet potatoes
  • Maintain protein: chicken, fish, eggs, legumes
  • Hydrate: minimum 2L of water per day
  • Avoid new or exotic foods (no digestive risks)

The day before

MealRecommendation
LunchNormal meal, carb-rich
DinnerLight, familiar, easy to digest
Evening snackOptional: yogurt, banana

Competition morning

If weigh-in is early in the morning:

  • Before weigh-in: little or nothing (depending on your weight margin)
  • After weigh-in: this is the critical moment

The ideal post-weigh-in breakfast:

  • White bread or crackers with honey
  • Banana
  • Fruit juice
  • Energy bar
  • Water + isotonic drink

Never eat something new on competition day. Always test your meals during training first.

Between fights

Depending on the tournament format, you might have 20 minutes or 2 hours between fights.

Short break (< 30 min):

  • A few sips of isotonic drink
  • 2-3 dates or fruit paste squares
  • Avoid eating heavy

Long break (> 1 hour):

  • Cereal bar
  • Banana
  • A few almonds
  • Water regularly

Absolutely avoid

  • Energy drinks (energy crash)
  • Fatty or fried foods
  • Too much fiber (digestive risk)
  • Too much sugar at once

After competition

Recovery starts within 30 minutes of your last fight:

  1. Rehydrate: water + isotonic drink
  2. Protein + carbs: chicken sandwich, rice + chicken, or protein shake with banana
  3. Natural anti-inflammatories: berries, turmeric

Evening meal

Treat yourself (you've earned it) but still prioritize:

  • Quality protein
  • Vegetables
  • Carbs to replenish your reserves
