The aim of this study was to examine the effect of ingesting a commerciallyavailable carbohydrate-electrolyte (CHO-E) solution on strenuousexercise performance. Ten apparently healthy male volunteers (Mean ± SD;age 20 ± 2 yrs; height 178 ± 7 cm; body mass 77 ± 10 kg; estimated VO2max56 ± 3 ml×kg-1×min-1) completed three experimental trials in randomorder separated by a minimum of 7 days. For each trial, subjects consumed(8 ml×kg-1 body mass) either a CHO-E solution (6% carbohydrate,50 mg Na/500 ml), a non-CHO-E placebo, or no fluid, 15 minutes priorto exercise. The exercise involved intermittent shuttle (20 m apart)running for 1 hr followed by an incremental shuttle running test toexhaustion. Subjects displayed longer exercise times when the CHO-E
