TI  - Cognitive Performance Enhancement Induced by Caffeine, Carbohydrate and Guarana 
      Mouth Rinsing during Submaximal Exercise.

AB  - The aim of this study was to investigate the influence of serial mouth rinsing 
      (MR) with nutritional supplements on cognitive performance (i.e., cognitive 
      control and time perception) during a 40-min submaximal exercise. Twenty-four 
      participants completed 4 counterbalanced experimental sessions, during which they 
      performed MR with either placebo (PL), carbohydrate (CHO: 1.6 g/25 mL), guarana 
      complex (GUAc: 0.4 g/25 mL) or caffeine (CAF: 67 mg/25 mL) before and twice 
      during exercise. The present study provided some important new insights regarding 
      the specific changes in cognitive performance induced by nutritional supplements. 
      The main results were: (1) CHO, CAF and GUA MR likely led participants to improve 
      temporal performance; (2) CAF MR likely improved cognitive control; and (3) CHO 
      MR led to a likely decrease in subjective perception of effort at the end of the 
      exercise compared to PL, GUA and CAF. Moreover, results have shown that 
      performing 40-min submaximal exercise enhances information processing in terms of 
      both speed and accuracy, improves temporal performance and does not alter 
      cognitive control. The present study opens up new perspectives regarding the use 
      of MR to optimize cognitive performance during physical exercise.
