      Fatiguing Exercise.

AB  - PURPOSE: To determine whether repeated carbohydrate (CHO) mouth rinsing would 
      improve neuromuscular performance during high-intensity fatiguing contractions. 
      METHODS: Eighteen young men (age 26.1 +/- 5.0 y, BMI 22.9 +/- 1.9) performed 3 
      maximal voluntary isometric contractions (MVIC(PRE)). Immediately after, they 
      completed 10-second mouth rinse with 6.4% maltodextrin solution (MAL), 7.1% 
      glucose solution (GLU), water (W), artificially sweetened solution (PLA), or a 
      control trial with no rinse (CON) in a crossover protocol. Subjects performed 5 
      sets of 30 isokinetic fatiguing contractions at 180 degrees /s, and an MVIC(POST) with 
      their elbow flexors was performed after each mouth rinse. Mechanical and 
      electromyographic (EMG) signals were recorded from the biceps brachii and 
      parameters of interest analyzed. RESULTS: When rinsing the mouth with a solution 
      containing CHO, independently of the sweetness, isokinetic performance was 
      enhanced as shown by the greater total work achieved in comparison with CON. The 
      decay of torque and mean fiber-conduction velocity (MFCV) recorded at the end of 
      the fatiguing task was lower when rinsing the mouth with GLU than with CON. The 
      torque recorded during the MVIC(POST) was greater with CHO with respect to CON, 
      and this was associated to a lower decay of MFCV. CONCLUSIONS: CHO mouth rinse 
      counteracts fatigue-induced decline in neuromuscular performance, supporting the 
      notion that CHO rinse may activate positive afferent signals able to modify motor 
      output. Repeated mouth rinsing with sweet and nonsweet CHO-containing solutions 
      can improve neuromuscular performance during an isokinetic intermittent fatiguing 
      task.
