TI  - Opposition of carbohydrate in a mouth-rinse solution to the detrimental effect of 
      mouth rinsing during cycling time trials.
PG  - 48-56
AB  - Studies have reported that rinsing the mouth with a carbohydrate (CHO) solution 
      improves cycling time-trial performance compared with rinsing with a placebo 
      solution. However, no studies have compared the effect of mouth rinsing with a 
      no-mouth-rinse control condition. The aim of this study was to compare the 
      effects of a CHO mouth rinse with those of a placebo rinse and a no-rinse 
      condition. Ten male cyclists completed three 1,000-kJ cycling time trials in a 
      randomized, counterbalanced order. At every 12.5% of the time trial completed, 
      participants were required to rinse their mouths for 5 s with either a 6.4% 
      maltodextrin solution (CHO), water (WA), or no solution (CON). Heart rate and 
      ratings of perceived exertion (RPE) were recorded every 25% of the time trial 
      completed. Time to completion was faster in both CHO (65.7 +/- 11.07 min) and CON 
      (67.6 +/- 12.68 min) than in WA (69.4 +/- 13.81 min; p = .013 and p = .042, 
      respectively). The difference between CHO and CON approached significance (p = 
      .086). There were no differences in heart rate or RPE between any conditions. In 
      summary, repeated mouth rinsing with water results in decreased performance 
      relative to not rinsing at all. Adding CHO to the rinse solution appears to 
      oppose this fall in performance, possibly providing additional benefits to 
      performance compared with not rinsing the mouth at all. This brings into question 
      the magnitude of the effect of CHO mouth rinsing reported in previous studies 
      that did not include a no-rinse condition.
