Most elite gymnasts reach their peak at age 15 or 16, training 20 to 36 hours per week when a body's calorie needs are at its highest. But in a sport where aesthetics can influence scores, some athletes adopt restrictive eating habits to control their physique.
"The ideal body type is not always the healthiest body type," says Sotiria Tzakas Everett, registered dietitian and staff nutritionist at the Women's Sports Medicine Center at Hospital for Special Surgery. "As both a growing child and athlete, young gymnasts have elevated nutritional needs that must be met despite constraining schedules and the pressure to stay lean." Everett recently presented on proper nutrition for the young gymnast at Special Surgery's 12th Annual Sports Medicine for the Young Athlete Symposium in New York.
Studies show that the average Body Mass Index (BMI), body fat percentage and daily energy intake of gymnasts are lower than those of non-gymnasts. Unfortunately, this behavior can lead to severe physical and psychological complications. Everett warns that gymnasts might develop unhealthy body images and experience lethargy, poor performance, frequent stress fractures and disorders such as amenorrhea. Characterized by missed menstrual periods, amenorrhea may be a symptom of hormonal imbalance due to elevated stress levels, excessive weight loss and over-exercising.
With more than 4 million gymnasts under the age of 18 in the United States, Everett emphasizes the role that coaches, trainers and parents can play in ensuring that young gymnasts receive the proper amount of nutrition. She recommends the following steps:
•Be sure gymnasts understand the importance and role of carbohydrates, protein, calcium and other nutrients. Education is critical.
•Calorie intake varies with a gymnast's skill level, weight and age. Be cognizant of how a gymnast's calorie needs will evolve over time.
•Be on the lookout for dips in energy levels, weight changes, altered moods and frequent stress fractures. These are all symptoms of undernourishment.
•Flag gymnasts with suspicious eating behavior for a nutritional, medical and psychological evaluation.
