Energy balance
Vegetarian diets may enhance endurance performance (VO2 max and time to exhaustion) compared to omnivorous diets, likely due to higher carbohydrate availability.
If your primary goal is endurance, a vegan or vegetarian diet may offer a slight advantage in VO2 max and time to exhaustion compared to an omnivorous diet, potentially due to higher carbohydrate intake.

O grupo da dieta vegan apresentou valores significativamente mais altos de VO2 max e tempo de resistência submáxima até à exaustão... quando comparado com o grupo da dieta omnívora
Why this rating

- Vegetarian athletes must pay special attention to micronutrients (Iron, Zinc, Calcium, Vitamin D, Vitamin B12) to support muscle development and prevent deficiencies that could impair performance.Good
- A well-planned vegetarian diet supports muscle hypertrophy and strength gains comparable to omnivorous diets when protein intake (1.6-2.2 g/kg/day) and energy balance are adequately managed.Moderate
