Sports nutrition is an evolving field, but there is a lack of data on Australian athletes' knowledge of current sports nutrition guidelines. Additionally, several tools used to assess nutrition knowledge (NK) have not undergone adequate validation. The purpose of this study was to assess and compare the sports NK of elite and nonelite Australian football (AF) athletes using a newly validated questionnaire-The Nutrition for Sport Knowledge Questionnaire. Elite AF players (n = 46) were recruited directly from their club dietitian and nonelite AF players (n = 53) were invited to participate via e-mail from their club president or secretary. The mean NK score of elite and nonelite AF players was 46 ± 16% and 51 ± 11%, respectively (p = .041). In both groups, knowledge of macronutrients, weight management, and alcohol was better than knowledge of supplements, micronutrients, and sports nutrition. Nonelite athletes achieved statistically significantly higher scores on the questionnaire subsections testing weight management (elite: 48 ± 18; nonelite: 57 ± 19, p = .019), micronutrients (elite: 39 ± 19; nonelite: 50 ± 16, p = .004), and alcohol (elite: 52 ± 13; nonelite: 71 ± 17, p = .002). While overall NK of Australian athletes was poor, scores varied greatly among individuals (range: 10-70%) and across the six subsections (topics) being assessed. Professionals working with athletes should undertake an assessment of the athletes' NK so that they can provide targeted education programs.
运动营养是一个不断发展的领域,但缺乏关于澳大利亚运动员对当前运动营养指南了解程度的数据。此外,一些用于评估营养知识(NK)的工具尚未经过充分验证。本研究的目的是使用新验证的问卷——《运动营养知识问卷》来评估和比较澳大利亚精英和非精英足球(AF)运动员的运动营养知识。精英AF球员(n = 46)直接从他们的俱乐部营养师处招募,非精英AF球员(n = 53)通过俱乐部主席或秘书发送的电子邮件邀请参与。精英和非精英AF球员的平均NK得分分别为46±16%和51±11%(p = 0.041)。在两组中,对宏量营养素、体重管理和酒精的了解都优于对补充剂、微量营养素和运动营养的了解。在问卷中测试体重管理(精英组:48±18;非精英组:57±19,p = 0.019)、微量营养素(精英组:39±19;非精英组:50±16,p = 0.004)和酒精(精英组:52±13;非精英组:71±17,p = 0.002)的子部分中,非精英运动员的得分在统计学上显著更高。虽然澳大利亚运动员的总体NK较差,但个体得分差异很大(范围:10 - 70%),并且在所评估的六个子部分(主题)中也存在差异。与运动员合作的专业人员应该对运动员的NK进行评估,以便他们能够提供有针对性的教育项目。
