Carbohydrate gel intake and endurance during repeated high-intensity shuttle runs

AI simplified

Abstract

Ingesting a carbohydrate gel improved run time to exhaustion from 4.2 ± 1.2 minutes to 6.1 ± 1.3 minutes after prolonged intermittent running.

  • Blood glucose levels were higher at multiple time points during exercise when consuming the carbohydrate gel compared to the placebo.
  • Participants ingested the carbohydrate gel before and during exercise, which is associated with improved performance.
  • The findings suggest that carbohydrate intake may help maintain energy levels during prolonged high-intensity activity.
