AB  - This study examined the effects of serial feedings of different carbohydrate 
      (CHO) solutions on plasma volume, gastric emptying (GE), and performance during 
      prolonged cycling exercise. Solutions containing 6 g% glucose-sucrose (CHO-6GS), 
      8.3 g% high fructose corn syrup (CHO-8HF), 6.3 g% high fructose corn syrup + 2 g% 
      glucose polymer (CHO-8HP), and a water placebo (WP) were compared. Ten trained 
      male cyclists performed four cycling trials consisting of 105 min at 70% VO2max 
      followed by a 15-min all-out, self-paced performance ride. Every 15 min the men 
      consumed one of the four test solutions. Blood samples were taken before, during, 
      and after exercise to determine blood glucose and plasma volume changes. There 
      were no significant differences in performance, GE, or plasma volume changes 
      between trials. Blood glucose was significantly elevated at the 105-min 
      time-point in all CHO trials when compared to WP. The CHO-8HF and CHO-8HP drinks 
      resulted in a significantly higher delivery of CHO to the intestine. Higher rates 
      of CHO oxidation during the steady-state ride were observed only with the CHO-6GS 
      drink.
