The effects of an experimental sports drink (Q) were compared with a commercial sports drink (D) of proven ergogenic efficacy. Seven highly trained subjects performed two hours of cycle ergometry exercise at approximately 65% maximal aerobic power (VO2 max) while receiving levels of Q and D in quantities designed to supply approximately 28% of the total energy requirement of the exercise task. Both Q and D formulations were supplied at 15 minute intervals at 16 degrees C, in volumes required to provide equivalent carbohydrate loads from two products of differing concentrations and compositions. Q was equally as effective as D in terms of the maintenance of plasma glucose concentrations during exercise, while selected physiological indices of work performance favoured Q. However, the time course of plasma glucose concentration changes during and after exercise indicated a trend towards more rapid uptake and assimilation of carbohydrate in the case of Q. The findings suggest that Q may provide a more readily available carbohydrate source during exercise and may enhance work performance through its ergogenic properties.
将一种实验性运动饮料（Q）的效果与一种已证实具有促力功效的商业运动饮料（D）进行了比较。七名训练有素的受试者在以大约65%的最大有氧功率（VO2 max）进行两小时的自行车测力计运动时，接受了按设计提供约28%运动任务总能量需求的Q和D剂量。Q和D配方均在15分钟的间隔内以16摄氏度供应，供应体积需根据两种不同浓度和成分的产品提供等量的碳水化合物负荷。就运动期间血浆葡萄糖浓度的维持而言，Q与D同样有效，而选定的工作表现生理指标更有利于Q。然而，运动期间和运动后血浆葡萄糖浓度变化的时间进程表明，在Q的情况下，碳水化合物的摄取和同化有更快的趋势。研究结果表明，Q可能在运动期间提供更容易利用的碳水化合物来源，并可能通过其促力特性提高工作表现。
