AB  - Fifteen male endurance athletes were studied to determine the effect of a glucose 
      polymer (GP) diet supplement on physiological and perceptual responses to 
      successive swimming, cycling and running exercise. Thirty min of swimming, 
      cycling and running at 70% VO2max, followed by a run to exhaustion at 90% VO2max 
      was performed after one week of training under two dietary conditions: 1) GP (230 
      g of GP consumed daily) and 2) placebo (P, saccharin-sweetened supplement 
      consumed daily). During GP, daily carbohydrate (CHO) intake was higher (p less 
      than 0.05) by 173 g or 14% of energy intake than during P, but total energy 
      intake was not significantly different. During 90 min of exercise, CHO 
      utilization and blood glucose were significantly higher under GP than P by an 
      average of 20.2% and 14.5%, respectively, but heart rate, ventilation, oxygen 
      uptake, ratings of perceived exertion, and plasma lactate were not different. Run 
      time to exhaustion at 90% VO2max was significantly longer by 1.2 min (23%) under 
      GP. The results suggest that a GP diet supplement may be of value during 
      endurance exercise by increasing the availability of CHO.
