Abstract

Intermittent endurance capacity increased by 34% with a 6% carbohydrate-electrolyte solution compared to a 10% solution.

  • Participants consuming the 6% solution performed better, completing 5.5 ± 0.8 minutes and covering 931 ± 172 meters.
  • In contrast, the 10% solution led to 4.1 ± 1.5 minutes and 706 ± 272 meters.
  • No significant differences were observed between the 2% and 6% solutions or between the 2% and 10% solutions.
  • Carbohydrate concentration did not significantly affect mean 15-m sprint time.
