Nutrition for Gymnasts: Balancing Low Body Weight and Power
In gymnastics, aesthetic pressure clashes with the demands of power. Underfueling threatens bone health, hormonal balance and performance.
Why Nutrition Matters in Gymnastics
In gymnastics, body weight directly affects performance — fighting gravity on jumps, precision in balance moves. But this also sets the stage for dangerous weight restriction, especially among young athletes.
The Concept of Energy Availability
Scientists use the concept of "energy availability":
Energy availability = Energy intake - Energy expended in exercise
If this value falls below 45 kcal per kg of fat-free body mass:
- Menstruation becomes irregular
- Bone mineral density decreases
- Growth slows (in young athletes)
- The risk of stress fractures rises
Getting Enough Calories
Young gymnasts (ages 12–17) may need 2,000–2,800 kcal a day; this varies with each athlete's training load. During intense periods, follow-up with a dietitian is essential.
Protein: The Foundation of Power
Recommended protein for gymnasts: 1.4–1.8 g/kg/day
Sources:
- Eggs (complete amino acid profile)
- Chicken, turkey
- Yogurt, cottage cheese
- Lentils + rice combination
Carbohydrates and Power Output
Explosive moves (flips, tumbles) rely mainly on the glycolytic system. Without enough glycogen, the quality and safety of these moves decline.
Daily target: 4–6 g/kg carbohydrate (depending on training intensity)
Key Nutrients for Bone Health
| Nutrient | Daily Target |
|---|---|
| Calcium | 1,000–1,300 mg |
| Vitamin D | 600–1,000 IU |
| Vitamin K2 | 45–90 mcg |
| Magnesium | 310–400 mg |
Milk, yogurt, cheese and dark leafy greens cover much of this need.
Post-Training Recovery Snack
- Yogurt + banana + granola
- Whole-grain bread + eggs
- Milk + cocoa powder
These combinations provide both protein for muscle repair and carbohydrates to replenish glycogen.
