  1. Values are presented as mean ± SE; n = 16; PL, Placebo; CPE, carbohydrate-protein-electrolyte; ST1, submaximal exercise trial 1, ST2, submaximal exercise trial 2; VO2, oxygen consumption; VCO2, expired carbon dioxide; RER, respiratory exchange ratio; CHOTOT, total carbohydrate oxidation; FATTOT, total fat oxidation; VE, minute ventilation; RPE, rating of perceived exertion. * denotes significant difference (P < 0.05) between trials within condition only. # denotes significant difference (P < 0.05) from PL within trial. ** denotes significant difference between conditions overall (P < 0.05).
