TI  - Carbohydrate ingestion improves performance of a new reliable test of soccer 
      performance.
PG  - 34-46
AB  - The aim of the study was to investigate the reliability of a new test of soccer 
      performance and evaluate the effect of carbohydrate (CHO) on soccer performance. 
      Eleven university footballers were recruited and underwent 3 trials in a 
      randomized order. Two of the trials involved ingesting a placebo beverage, and 
      the other, a 7.5% maltodextrin solution. The protocol comprised a series of ten 
      6-min exercise blocks on an outdoor Astroturf pitch, separated by the performance 
      of 2 of the 4 soccer-specific tests, making the protocol 90 min in duration. The 
      intensity of the exercise was designed to be similar to the typical activity 
      pattern during soccer match play. Participants performed skill tests of 
      dribbling, agility, heading, and shooting throughout the protocol. The 
      coefficients of variation for dribbling, agility, heading, and shooting were 
      2.2%, 1.2%, 7.0%, and 2.8%, respectively. The mean combined placebo scores were 
      42.4 +/- 2.7 s, 43.1 +/- 3.7 s, 210 +/- 34 cm, and 212 +/- 17 points for agility, 
      dribbling, heading, and kicking, respectively. CHO ingestion led to a combined 
      agility time of 41.5 +/- 0.8 s, for dribbling 41.7 +/- 3.5 s, 213 +/- 11 cm for 
      heading, and 220 +/- 5 points for kicking accuracy. There was a significant 
      improvement in performance for dribbling, agility, and shooting (p < .05) when 
      CHO was ingested compared with placebo. In conclusion, the protocol is a reliable 
      test of soccer performance, and ingesting CHO leads to an improvement in soccer 
      performance.
