Child nutrition is a key element for children's physical, cognitive, and emotional development. When combined with the practice of sports such as artistic gymnastics, food plays an even more critical role. This sport requires strength, flexibility, agility, balance and endurance, in addition to promoting intense energy expenditure. Therefore, a balanced diet that is appropriate to individual needs is essential for healthy growth, athletic performance and the prevention of health problems. Childhood is marked by accelerated growth, in which the body demands energy and nutrients for the development of bones, muscles, and metabolic functions. For children who practice artistic gymnastics, nutrition goes beyond the basics and must meet specific needs.
