Abstract

Sports supplements are used extensively by people involved in competitive sports. However, a proportion of sports supplements contain World Anti-Doping Agency (WADA) Prohibited Substances, which have the potential to cause an anti-doping rule violation (ADRV). In 2022, Sport Integrity Australia (SIA) contracted Human and Supplements Testing Australia (HASTA) to purchase and analyse 200 sports supplement products available in the Australian online marketplace. The aim of the survey was to determine the likelihood of purchasing a product containing one or more WADA Prohibited Substances. Of the 200 products purchased, 35% contained WADA Prohibited Substances, with the majority of these findings being stimulants. Products marketed as pre-workouts, fat burners and muscle builders were the most likely to contain prohibited substances. It is notable that 83% of the WADA Prohibited Substances detected were naturally occurring compounds; only two of the products contained high levels of synthetic stimulants. Fifty-seven percent of the products that contained WADA Prohibited Substances did not have the substances labelled as ingredients on the packaging or website. Athlete education concerning sports supplements should remain a high priority, with a prevalence rate of approximately one in three products purchased containing WADA Prohibited Substances. To reduce the risk of an inadvertent ADRV, if an athlete wishes to use sports supplements, they should consult with their medical practitioner or accredited sports dietician (ASD) as to whether they require them and, if so, only take products that have been independently tested.

澳大利亚在线市场中WADA禁用物质流行率的运动补充剂分析调查。
运动补品被参与竞技体育的人广泛使用。然而,一部分运动补充剂含有世界反兴奋剂机构(WADA)禁用物质,这些物质有可能导致违反反兴奋剂规则(ADRV)。2022年,澳大利亚体育诚信(SIA)与澳大利亚人体和补充剂测试(HASTA)签订合同,购买并分析澳大利亚在线市场上的200种运动补充剂产品。调查的目的是确定购买含有一种或多种世界反兴奋剂机构禁用物质的产品的可能性。在购买的200种产品中,35%含有世界反兴奋剂机构禁用物质,其中大多数是兴奋剂。作为锻炼前、脂肪燃烧剂和肌肉增强剂销售的产品最有可能含有违禁物质。值得注意的是,检测到的WADA禁用物质中有83%是天然存在的化合物;其中只有两种产品含有高水平的合成兴奋剂。含有世界反兴奋剂机构禁用物质的产品中,57%的产品在包装或网站上没有标明这些物质的成分。运动员关于运动补充剂的教育仍应是一个高度优先事项,普及率约为三分之一的产品购买含有世界反兴奋剂机构的禁用物质。为了减少意外ADRV的风险,如果运动员希望使用运动补充剂,他们应该咨询他们的医生或认可的运动营养师(ASD),以确定他们是否需要,如果需要,只服用经过独立测试的产品。

期刊介绍: As the incidence of drugs escalates in 21st century living, their detection and analysis have become increasingly important. Sport, the workplace, crime investigation, homeland security, the pharmaceutical industry and the environment are just some of the high profile arenas in which analytical testing has provided an important investigative tool for uncovering the presence of extraneous substances. In addition to the usual publishing fare of primary research articles, case reports and letters, Drug Testing and Analysis offers a unique combination of; ‘How to’ material such as ‘Tutorials’ and ‘Reviews’, Speculative pieces (‘Commentaries’ and ‘Perspectives'', providing a broader scientific and social context to the aspects of analytical testing), ‘Annual banned substance reviews’ (delivering a critical evaluation of the methods used in the characterization of established and newly outlawed compounds). Rather than focus on the application of a single technique, Drug Testing and Analysis employs a unique multidisciplinary approach to the field of controversial compound determination. Papers discussing chromatography, mass spectrometry, immunological approaches, 1D/2D gel electrophoresis, to name just a few select methods, are welcomed where their application is related to any of the six key topics listed below.
