运动员在英联邦运动会期间使用的补充剂已从历史上的肝脏和心脏等器官制品，演变为现代的肌酸、咖啡因和蛋白质等科学配方[1]。最有效的补充剂可以改善运动表现约3%，在胜负差异不足1%的竞技项目中具有显著意义[1]。然而，约三分之一的兴奋剂违规事件与补充剂有关，且多达50%的补充剂产品被检测出含有禁用物质污染[1]。
为了帮助运动员安全有效地使用补充剂，澳大利亚运动营养专家开发了AIS运动补充剂框架[1]。该框架于2000年在奥运会前推出，是世界首创的系统，通过科学评估补充剂的安全性、有效性和合规性，同时最小化禁用物质污染风险[1]。肌酸的应用也体现了补充剂用途的演变——除了传统的增加肌肉质量和细胞水合外，各支足球队现已将其用于预防脑震荡[1]。
The supplements used by competing athletes at the Commonwealth Games have undergone significant transformation over time, evolving from traditional remedies to scientifically formulated products [1]. Modern competitors now rely on substances such as creatine, caffeine, and protein to gain competitive advantages [1].
The performance impact of supplements can be substantial in closely contested sports. The most effective supplements can improve athletic performance by approximately 3 percent, a margin that proves decisive in competitions where winning margins fall below 1 percent [1]. However, the supplementation landscape carries considerable risks. Approximately one-third of doping violations have been attributed to supplements, with studies indicating that as many as 50 percent of supplements contain contamination from prohibited substances [1].
To address these concerns, Australian sports nutrition experts developed the AIS Sports Supplement Framework, which was introduced ahead of the 2000 Olympics as a world-first initiative [1]. This framework employs systematic evaluation of supplements across three critical dimensions: safety, efficacy, and compliance with anti-doping regulations, enabling athletes to use supplements scientifically while minimizing the risk of inadvertent exposure to banned substances [1].
The applications of supplementation have also expanded beyond traditional uses. Creatine, historically employed to build muscle mass and enhance cellular hydration, is now being utilized by football teams as a preventative measure against concussions [1].
