TI  - The effect of carbohydrate ingestion on performance during a simulated soccer 
      match.

AB  - AIM: This study investigated how performance was affected after soccer players, 
      in a postprandial state, ingested a 7% carbohydrate (CHO) solution compared to a 
      placebo (0% CHO) during a simulated soccer match. METHODS: Using a double-blind 
      placebo-controlled design, 22 trained male league soccer players (age: 24 +/- 7 
      years, wt: 73.4 +/- 12.0 kg, VO2max: 51.8 +/- 4.3 mL O2/kg/min) completed two trials, 
      separated by 7 days, during which they ingested, in random order, 700 mL of 
      either a 7% CHO or placebo drink during a simulated soccer match. Ratings of 
      perceived exertion (RPE), agility, timed and run to fatigue were measured during 
      the trials. RESULTS: Change in agility times was not altered by CHO vs. placebo 
      ingestion (0.57 +/- 1.48 vs. 0.66 +/- 1.00, p = 0.81). Timed runs to fatigue were 381 
      +/- 267 s vs. 294 +/- 159 s for the CHO and placebo drinks, respectively (p = 0.11). 
      Body mass modified the relationship between time to fatigue and drink ingestion 
      (p = 0.02 for drink x body mass), such that lower body mass was associated with 
      increased time to fatigue when the players ingested CHO, but not placebo. RPE 
      values for the final stage of the simulated soccer match were 8.5 +/- 1.7 and 8.6 +/- 
      1.5 for the CHO and placebo drinks respectively (p = 0.87). CONCLUSIONS: The 
      group data showed that the 7% CHO solution (49 g CHO) did not significantly 
      improve performance during a simulated soccer match in league soccer players who 
      had normal pre-match nutrition. However, when adjusting for body mass, increasing 
      CHO intake was associated with improved time to fatigue during the simulated 
      soccer match.
