Caffeine and exercise performance

Summary of a review article looking at published meta-analysis on effect of caffeine on exercise performance.

Who

Healthy persons of any age or sex.

Design

Umbrella review of 21 meta-analysis (11 reviews).

Outcome measures/tests

Exercise performance: maximal speed during running, cycling or rowing, aerobic endurance, 30s Wingate test, isokinetic strength assessment, 1RM, vertical jump, and muscular endurance.

Main results

  • In the 21 meta-analyses, the prevalence of male-only studies ranged from 72-100%. Not many studies have tested the effect of caffeine on women.
  • A caffeine dose of 6mg per kg was most commonly used.
  • Most studies did not use coffee but caffeine powder, energy drinks, bars, or gels. However, the authors calculated that two cups of coffee 60 minutes before the exercise could have an ergogenic effect on many individuals.

Take home message

For a clinician
Caffeine had an enhancing effect on acute physical performance in aerobic endurance, muscle endurance, muscle strength, and aerobic power.
For a parent
Caffeine ingestion may increase physical performance within a few hours.
For an athlete
Caffeine ingestion may increase physical performance within a few hours.
