      Training.

AB  - The aim of the present study was to test the effectiveness of carbohydrate (CHO) 
      feeding supplemented every 2.5-km, as in official races, on the performance, 
      rating of perceived exertion (RPE), and glycaemia during a 10-km intermittent 
      training workout in elite open-water swimmers. A randomized crossover design was 
      used. Participants completed two 10-km intermittent training sessions (20 x 
      500-m). The relative velocity was expressed in percentage of a single 500-m. 
      Glycaemia was monitored by continuous glucose monitoring. Participants had to 
      ingest either 1 L of tap water (WAT; 0.50 L.h(-1)) or 120 g of CHO in the form of 
      8% solution (60 g.h(-1)). The 15-point RPE scale was used during the trials. A 
      two-way ANOVA for repeated measures was performed (p < 0.05). The relative 
      velocity of each 500-m was not significantly different between the two trials. No 
      significant differences emerged in the relative velocity of the last 500-m 
      between trials. Average RPE was not statistically different between the two 
      trials (11 +/- 3 in WAT and 12 +/- 3 in CHO). In the last 500-m, glycaemia was 
      significantly higher in the CHO trial (5.92 +/- 0.47 mmol.L(-1) in CHO; 5.61 +/- 0.61 
      mmol.L(-1) in WAT). CHO ingestion did not improve performance or affect RPE 
      during a 10-km intermittent training in elite open-water swimmers.
