Carbohydrate electrolyte solutions (CES) with low-dose caffeine improved memory before exercise. Post-exercise, CES with low and medium caffeine doses enhanced cognitive functions in athletes.

Area of Science:

  • Sports Science
  • Cognitive Neuroscience
  • Nutritional Science

Background:

  • Athletes often use carbohydrate electrolyte solutions (CES) to improve performance.
  • Caffeine is a known ergogenic aid, but its effects on cognitive function alongside CES and exercise are less understood.

Purpose of the Study:

  • To investigate the effects of varying caffeine doses in CES on cognitive functions.
  • To examine the combined impact of CES, caffeine, and strenuous exercise on cognitive performance.

Main Methods:

  • A double-blind, cross-over study involving 15 male endurance athletes.
  • Participants consumed water placebo, CES placebo, or CES with low, medium, or high caffeine doses.
  • Cognitive tests (attention, psychomotor, memory) were administered before and after a 1-hour cycling time trial.

Main Results:

  • Before exercise, CES with low-dose caffeine enhanced long-term memory compared to placebos.
  • After exercise, CES with low and medium caffeine doses significantly improved all tested cognitive functions (attention, psychomotor, memory) versus placebo.
  • High-dose caffeine did not show additional cognitive benefits post-exercise.

Conclusions:

  • Low to moderate doses of caffeine in CES can enhance cognitive function in athletes.
  • These findings provide practical evidence for using caffeine-containing CES to support cognitive performance during and after strenuous exercise.
