We undertook a dietary survey of 167 Australian Olympic team athletes (80 females and 87 males) competing in endurance sports (n = 41), team sports (n = 31), sprint- or skill-based sports (n = 67), and sports in which athletes are weight-conscious (n = 28). Analysis of their 7-day food diaries provided mean energy intakes, nutrient intakes, and eating patterns. Higher energy intakes relative to body mass were reported by male athletes compared with females, and by endurance athletes compared with other athletes. Endurance athletes reported substantially higher intakes of carbohydrate (CHO) than other athletes, and were among the athletes most likely to consume CHO during and after training sessions. Athletes undertaking weight-conscious sports reported relatively low energy intakes and were least likely to consume CHO during a training session or in the first hour of recovery. On average, athletes reported eating on approximately 5 separate occasions each day, with a moderate relationship between the number of daily eating occasions and total energy intake. Snacks, defined as food or drink consumed between main meals, provided 23% of daily energy intake and were chosen from sources higher in CHO and lower in fat and protein than foods chosen at meals. The dietary behaviors of these elite athletes were generally consistent with guidelines for sports nutrition, but intakes during and after training sessions were often sub-optimal. Although it is of interest to study the periodicity of fluid and food intake by athletes, it is difficult to compare across studies due to a lack of standardized terminology.
我们对167名参加耐力运动(n = 41)、团队运动(n = 31)、短跑或技能类运动(n = 67)以及注重体重的运动(n = 28)的澳大利亚奥运代表队运动员(80名女性和87名男性)进行了饮食调查。分析他们7天的饮食日记得出了平均能量摄入量、营养素摄入量和饮食模式。与女性运动员相比,男性运动员以及与其他运动员相比,耐力项目运动员报告的相对于体重的能量摄入量更高。耐力项目运动员报告的碳水化合物(CHO)摄入量显著高于其他运动员,并且是训练期间和训练后最有可能摄入CHO的运动员群体之一。参加注重体重项目的运动员报告的能量摄入量相对较低,并且在训练期间或恢复的第一个小时内摄入CHO的可能性最小。平均而言,运动员报告每天大约在5个不同场合进食,每日进食次数与总能量摄入量之间存在适度关联。零食定义为主餐之间食用的食物或饮料,提供了23%的每日能量摄入量,并且与正餐时选择的食物相比,零食的CHO含量更高,脂肪和蛋白质含量更低。这些精英运动员的饮食行为总体上符合运动营养指南,但训练期间和训练后的摄入量往往不理想。尽管研究运动员液体和食物摄入的周期性很有意义,但由于缺乏标准化术语,不同研究之间难以进行比较。
