This study examines the degree of under-reporting of energy intake by elite, female gymnasts, and the impact this predicted under-reporting has on associated macro and micro nutrient intake. Twenty-eight female U.S. national team artistic gymnasts participated in the study. Dietary intake was assessed using 3-day food records, and the degree of under-reporting was predicted from the ratio of reported energy intake (EI) to predicted basal metabolic rate (BMRestd), using the standards described by Goldberg et al. (10). Sixty-one percent of the subjects had an EI/BMRestd ratio of < 1.44, and were classified as under-reporters. The under-reporters had higher BMIs and percent body fat, and lower reported total energy intakes than the adequate energy reporters. Additionally, under-reporting of energy intake had a significant impact on reported micro nutrient intake. The under-reporting of energy intake seen in these subjects has an impact on the reported intake of macro and micro nutrients that can influence the interpretation of the nutritional status of these athletes and the strategy for nutrition intervention. Therefore, when assessing dietary intakes of elite gymnasts, some means of determining the accuracy of the reported energy and nutrient intake should be employed to more accurately identify the true nutritional problems experienced by these elite athletes.
本研究调查了精英女子体操运动员能量摄入报告不足的程度，以及这种预测的报告不足对相关宏量和微量营养素摄入的影响。28名美国国家艺术体操女运动员参与了该研究。通过3天的饮食记录评估饮食摄入量，并根据报告的能量摄入量（EI）与预测基础代谢率（BMRestd）的比值，采用Goldberg等人（10）描述的标准预测报告不足的程度。61%的受试者EI/BMRestd比值<1.44，被归类为报告不足者。与能量报告充足者相比，报告不足者的体重指数和体脂百分比更高，报告的总能量摄入量更低。此外，能量摄入报告不足对报告的微量营养素摄入有显著影响。这些受试者中出现的能量摄入报告不足会影响宏量和微量营养素的报告摄入量，进而可能影响对这些运动员营养状况的解读以及营养干预策略。因此，在评估精英体操运动员的饮食摄入量时，应采用某种方法来确定报告的能量和营养素摄入量的准确性，以便更准确地识别这些精英运动员所面临的真正营养问题。
