  1. Table 3 shows the average data for key physiological, power output and subjective perception of exertion vaiables over both the oxidation and performance trials. Data are presented as mean ± SE; (n = 14 for oxidation trial; n = 6 for performance trial finishers). P, Placebo; MD, maltodextrin beverage; MD + F, maltodextrin-fructose beverage; RPE, Rating of Perceived Exertion. *denotes a significant difference to MD and P (P < 0.03). † denotes significant difference to P (P < 0.05).‡ denotes a significant difference to MD (P = 0.021) within trial only.
