      randomized controlled trial in Jordanian men.

AB  - Mouth rinsing using a carbohydrate (CHO) solution has been suggested to improve 
      physical performance in fasting participants. This study examined the effects of 
      CHO mouth rinsing during Ramadan fasting on running time to exhaustion and on 
      peak treadmill speed (V(peak)). In a counterbalanced crossover design, 18 
      sub-elite male runners (Age: 21 +/- 2 years, Weight: 68.1 +/- 5.7 kg, VO(2max): 
      55.4 +/- 4.8 ml/kg/min) who observed Ramadan completed a familiarization trial and 
      three experimental trials. The three trials included rinsing and expectorating a 
      25 mL bolus of either a 7.5% sucrose solution (CHO), a flavour and taste matched 
      placebo solution (PLA) for 10 s, or no rinse (CON). The treatments were performed 
      prior to an incremental treadmill test to exhaustion. Three-day dietary and 
      exercise records were obtained on two occasions and analysed. Anthropometric 
      characteristics were obtained and recorded for all participants. A main effect 
      for mouth rinse on peak velocity (V(peak)) (CHO: 17.6 +/- 1.5 km/h; PLA: 
      17.1 +/- 1.4 km/h; CON: 16.7 +/- 1.2 km/h; P < .001, eta(p)(2) = 0.49) and time to 
      exhaustion (CHO: 1282.0 +/- 121.3 s; PLA: 1258.1 +/- 113.4 s; CON: 1228.7 +/- 98.5 s; 
      P = .002, eta(p)(2) = 0.41) was detected, with CHO significantly higher than PLA 
      (P < .05) and CON (P < .05). Oxygen consumption, heart rate, respiratory exchange 
      ratio, and rating of perceived exertion were not significantly different between 
      treatments or trials (P > .05). Energy availability from dietary analysis, body 
      weight, and fat-free mass did not change during the last two weeks of Ramadan 
      (P > .05). This study concludes that carbohydrate mouth rinsing improves running 
      time to exhaustion and peak treadmill speed under Ramadan fasting conditions.
