The purpose of this study was to assess the nutrition knowledge and the factors determining this knowledge in Iranian college basketball and football athletes. By highlighting gaps in nutrition knowledge of these athletes, sport nutrition professionals may begin to address these gaps by educating athletes with a view toward minimizing injury and enhancing sport performance. Sixty-six basketball and 141 football players (response rate 78.4%) from 4 medical and 8 nonmedical universities in Tehran agreed to participate in this cross-sectional study. A 2-part questionnaire was used; the first part comprised questions identifying demographic information, and the second part comprised a previously well-validated questionnaire on sport nutrition knowledge. The overall knowledge score was 33.2% (+/- 12.3%). Men scored 28.2% (+/- 12.7%), and women, 38.7% (+/- 14.2%). In both genders, the highest score was obtained for the nutrients subcategory, and the supplements subcategory was the most poorly answered. When compared with their peers, a significantly higher score was obtained by women (p < .001), athletes at medical universities (p < .001), and those obtaining nutrition information from reputable sources (p = .03). The coach was cited by 89.4% of athletes as their main source of nutrition information. This study showed that the sport nutrition knowledge of these athletes is inadequate. Considering that this substandard level of knowledge may contribute to poor dietary behaviors, these athletes would benefit from nutrition-related training and education.
本研究旨在评估伊朗大学生篮球和足球运动员的营养知识水平，以及影响这些知识的因素。通过了解这些运动员营养知识的不足，运动营养专业人员可以通过教育运动员来弥补这些不足，从而减少运动损伤，提高运动表现。来自德黑兰 4 所医学院和 8 所非医学院的 66 名篮球运动员和 141 名足球运动员（回应率为 78.4%）同意参与这项横断面研究。研究使用了两部分问卷，第一部分包括识别人口统计学信息的问题，第二部分包括先前经过充分验证的运动营养知识问卷。总体知识得分为 33.2%（+/-12.3%）。男性得分为 28.2%（+/-12.7%），女性得分为 38.7%（+/-14.2%）。在男女两性中，营养物质亚类的得分最高，而补充剂亚类的得分最低。与同龄人相比，女性的得分显著更高（p<0.001），来自医学院的运动员得分更高（p<0.001），而从可靠来源获取营养信息的运动员得分更高（p=0.03）。89.4%的运动员表示，教练是他们获取营养信息的主要来源。本研究表明，这些运动员的运动营养知识不足。考虑到这种知识水平较低可能导致不良的饮食行为，这些运动员将从营养相关的培训和教育中受益。
