Nutrition education visual tools are designed to help the general population translate science into practice. The purpose of this study was to validate the Athlete's Plate (AP) to ensure that it meets the current sport nutrition recommendations for athletes. Twelve registered dietitians (RDs; 10 female and 2 male) volunteered for the study. Each registered dietitian was asked to create three real and virtual plates at three different times corresponding to breakfast, lunch, and dinner, and the three different AP training loads, easy (E), moderate (M), and hard (H), divided into two weight categories (male 75 kg and female 60 kg). Data of the real and virtual plates were evaluated using Computrition software (v. 18.1; Computrition, Chatsworth, CA). Statistical analyses were conducted by SPSS (version 23.0; IBM, Armonk, NY) to compare the difference between each training load category (E, M, and H) and the recommendations. No statistically significant differences were found among the created plates and the recommendations for energy, carbohydrates, fat, and fiber for E, M, and H. Protein relative to body mass (BM) was higher than recommended for E (1.9 ± 0.3 g·kg-1 BM·day-1, p = .003), M (2.3 ± 0.3 g·kg-1 BM·day-1, p < .001), and H (2.9+0.5 g·kg-1 BM·day-1, p < .001). No differences were found for the macronutrient distribution by gender when correcting for kilograms of body mass. The authors conclude that the AP meets the nutrition recommendations for athletes at different training intensities for energy, carbohydrates, fat, and fiber, but exceeds the recommendations for protein. Further research should consider this protein discrepancy and develop an AP model that meets, besides health and performance goals, contemporary guidelines for sustainability.

运动员餐盘营养教育工具的验证：第一阶段。

营养教育视觉工具旨在帮助一般人群将科学转化为实践。本研究的目的是验证运动员餐盘 (AP) 以确保其符合当前针对运动员的运动营养建议。12 名注册营养师（RD；10 名女性和 2 名男性）自愿参加了这项研究。每位注册营养师被要求在三个不同时间分别制作三个真实和虚拟的盘子，分别对应早餐、午餐和晚餐，以及三种不同的 AP 训练负荷，简单 (E)、中等 (M) 和困难 (H)，分为分为两个体重类别（男性 75 公斤和女性 60 公斤）。使用 Computrition 软件 (v. 18.1; Computrition, Chatsworth, CA) 评估真实和虚拟板的数据。统计分析由 SPSS（23.0 版；IBM、Armonk、NY) 来比较每个训练负荷类别（E、M 和 H）与建议之间的差异。在创建的盘子和 E、M 和 H 的能量、碳水化合物、脂肪和纤维建议之间没有发现统计学上的显着差异。蛋白质相对于体重 (BM) 的建议高于 E (1.9 ± 0.3 g· kg-1 BM·day-1, p = .003), M (2.3 ± 0.3 g·kg-1 BM·day-1, p < .001), 和 H (2.9+0.5 g·kg-1 BM·第 1 天，p < .001）。在校正公斤体重时，没有发现按性别划分的常量营养素分布存在差异。作者得出结论，AP 满足不同训练强度的运动员对能量、碳水化合物、脂肪和纤维的营养建议，但超过了蛋白质的建议。
