AB  - Ten endurance-trained males were recruited to examine the possible role of 
      carbohydrate (CHO) receptors in the mouth influencing exercise performance in the 
      heat. Volunteers completed an incremental test to exhaustion to determine peak 
      oxygen uptake, a familiarisation trial, followed by 2 experimental trials. Trials 
      consisted of a 1-h time trial undertaken in a climatic chamber maintained at 30 
       degrees C, 60% relative humidity. Immediately before, and at regular intervals 
      throughout exercise, subjects ingested a bolus of water and then were provided 
      with either a placebo (PLA) or a 6.4% glucose (CHO) solution to rinse in the 
      mouth for 10 s before being expectorated. There was no difference in total work 
      done between the PLA and CHO trials (758.8 +/- 149.0 kJ; 762.6 +/- 141.1 kJ; P = 
      0.951). Pacing was also similar, with no differences in power output apparent 
      during the experimental trials (P = 0.546). Core temperature (P = 0.615), heart 
      rate (P = 0.505), ratings of perceived exertion (P = 0.181), and perceived 
      thermal stress (P = 0.416) were not influenced by the nature of the intervention. 
      Blood glucose concentrations were similar during the CHO and PLA trials (P = 
      0.117). In contrast to the findings of several studies undertaken in temperate 
      conditions, the present investigation failed to support role of oral sensing of 
      CHO in influencing performance during prolonged exercise in warm conditions.
