Web-based 24-h dietary recalls and questionnaires were obtained from 553 Dutch well-trained athletes. The total energy and macronutrient intake was compared between discipline-categories (endurance, team, and strength) within gender, and dietary inadequacy, i.e., too low or high intakes, according to selected recommendations and guidelines, was evaluated by applying a probability approach. On average, 2.83 days per person were reported with a mean energy intake of 2566-2985 kcal and 1997-2457 kcal per day, for men and women, respectively. Between disciplines, small differences in the mean intake of energy and macronutrients were seen for both men and women. Overall, 80% of the athletes met the suggested lower-limit sport nutrition recommendation of 1.2 g·kg of protein per day. The carbohydrate intake of 50%-80% of athletes was between 3 and 5 g·kg bodyweight, irrespective of the category of their discipline. This can be considered as low to moderate, in view of their daily total exercise load (athletes reported on average ~100 minutes per day). In conclusion, only small differences in the mean energy and macronutrient intake between elite endurance, strength, and team sport athletes, were found. The majority of the athletes were able to meet the generally accepted protein recommendation for athletes, of 1.2 g·kg. However, for most athletes, the carbohydrate intake was lower than generally recommended in the existing consensus guidelines on sport nutrition. This suggests that athletes could either optimize their carbohydrate intake, or that average carbohydrate requirements merit a re-evaluation.
我们从553名训练有素的荷兰运动员那里获取了基于网络的24小时饮食回顾和调查问卷。比较了不同性别中各项目类别(耐力项目、团队项目和力量项目)之间的总能量和宏量营养素摄入量,并根据选定的建议和指南,采用概率方法评估了饮食不足情况,即摄入量过高或过低。平均而言,男性和女性每人分别报告了2.83天的饮食情况,男性平均每日能量摄入量为2566 - 2985千卡,女性为1997 - 2457千卡。在不同项目之间,男性和女性的能量及宏量营养素平均摄入量存在细微差异。总体而言,80%的运动员达到了每天每千克体重1.2克蛋白质的运动营养建议下限。50% - 80%的运动员碳水化合物摄入量在每千克体重3至5克之间,与他们所从事项目的类别无关。鉴于他们的每日总运动负荷(运动员平均每天报告约100分钟),这可被视为低至中等水平。总之,在精英耐力项目、力量项目和团队项目运动员之间,平均能量和宏量营养素摄入量仅存在细微差异。大多数运动员能够达到运动员普遍接受的每千克体重1.2克蛋白质的建议摄入量。然而,对于大多数运动员来说,碳水化合物摄入量低于现有运动营养共识指南中的普遍建议。这表明运动员要么优化他们的碳水化合物摄入量,要么平均碳水化合物需求量值得重新评估。
