Abstract

Ingestion of a 6% carbohydrate-electrolyte solution increased time to fatigue by 24.4% during high-intensity exercise.

  • Time to fatigue during intermittent running was 5.1 minutes with carbohydrate-electrolyte compared to 4.1 minutes with a placebo.
  • Distance covered during the run to exhaustion was significantly greater in the carbohydrate-electrolyte trial (851 meters) compared to the placebo (694 meters).
  • No significant differences were found in sprint times or heart rate during the initial exercise periods between the two trials.
