      Suppressed Feelings of Thirst and Hunger without Changing Exercise Performance.

AB  - The present guidelines for sports nutrition recommend relatively higher doses of 
      carbohydrates (CHO) for endurance exercise. There is a need for novel food 
      products that are solid but easy to swallow and supply a large dose of CHO 
      without gastrointestinal distress (ingesting a large amount of sugar solution may 
      cause gastrointestinal distress because of its high osmolality). We prepared a 
      modified rice cake (SPRC, sweet potato rice cake) and assessed its properties in 
      swallowing and mastication; we also assessed the availability of this modified 
      rice cake as a CHO source during endurance exercise. The number of chewing 
      strokes with the SPRC tended to be lower compared to glutinous rice cakes. The 
      exercise protocol consisted of 1 h at 80% VO(2max) plus a continuous time trial. 
      The subjects were administered a commercially available jelly drink (CHO gel) or 
      SPRC at 0 and 30 min during exercise and immediately after completing the time 
      trial. Heart rate, oxygen consumption, blood glucose elevation, and the rate of 
      perceived exertion did not differ among the trials during exercise. However, the 
      visual analog scale rating revealed that SPRC significantly suppressed hunger and 
      sweetness ratings (p<0.05) and tended to suppress thirst ratings (p<0.10) during 
      exercise. The palatability rating did not differ between the SPRC and CHO gel 
      during exercise at 80% VO(2max) and immediately after the time trial. In 
      conclusion, pre- and during exercise ingestion of the SPRC suppressed sweetness, 
      thirst, and hungry ratings without interfering with exercise performance.
