Adolescent high-performance gymnasts are considered to be at risk for low energy intake. The aim of the present study was to determine the effects of implementing a nutritional education program during the sports season on the nutritional status and nutrition knowledge of the female artistic gymnasts from the Technification Center of the Balearic Islands (n = 24; age, 14.1 ± 2.3 years). A quasi-experimental intervention design was applied, which consisted of implementing a nutritional education program of seven sessions given during eight months. Measurements of nutritional intake, nutrition knowledge, and anthropometric parameters, as well as hematological and biochemical blood parameters, were performed. Gymnasts reported low energy and carbohydrate intakes, with significant increases during the study (energy, 28.3 ± 1.4 vs. 32.8 ± 1.4 kcal kg, = 0.015, carbohydrate 3.2 ± 0.2 vs. 3.9 ± 0.2 g kg, = 0.004). The average values for parameters such as hemoglobin, ferritin, lipoprotein, and vitamin C and E levels in the plasma were within normal ranges. Low intakes of most of the food groups were observed during the study, with similar initial and final values. Nutrition knowledge did not change as a result of the study (28.0 ± 1.7 vs. 31.1 ± 1.3, = 0.185). In conclusion, gymnasts reported low energy intakes. However, blood markers and most of the anthropometrical parameters measured were within normal ranges. The nutrition education program implemented did not produce significant improvements in the dietary habits or nutritional knowledge of gymnasts.
青春期高水平体操运动员被认为存在能量摄入不足的风险。本研究旨在确定在运动赛季实施营养教育计划对巴利阿里群岛技术化中心的女性艺术体操运动员(n = 24;年龄,14.1 ± 2.3 岁)的营养状况和营养知识的影响。采用了准实验干预设计,包括在八个月期间实施七次营养教育计划。测量了营养摄入、营养知识和人体测量参数,以及血液的血液参数。体操运动员报告的能量和碳水化合物摄入量较低,在研究期间有显著增加(能量,28.3 ± 1.4 与 32.8 ± 1.4 kcal kg, = 0.015,碳水化合物 3.2 ± 0.2 与 3.9 ± 0.2 g kg, = 0.004)。血红蛋白、铁蛋白、脂蛋白和血浆中维生素 C 和 E 水平等参数的平均值均在正常范围内。在研究期间,观察到大多数食物组的摄入量较低,初始和最终值相似。由于研究,营养知识并没有改变(28.0 ± 1.7 与 31.1 ± 1.3, = 0.185)。总之,体操运动员报告的能量摄入量较低。然而,血液标志物和测量的大多数人体测量参数均在正常范围内。实施的营养教育计划并没有显著改善体操运动员的饮食习惯或营养知识。
