Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Effect of ephedra and caffeine on resistance-trained athletes

     The International Olympic Committee no longer bans caffeine and ephedrine-related alkaloids.

    So, what’s their effect on muscular strength and anaerobic power?

    First, the details.

    • 9 resistance-trained male athletes participated in each phase of the study.
      • Placebo
      • Caffeine 300 mg
      • Caffeine 300 mg + ephedra 60 mg
    • 45 minutes after taking the treatment they were tested for maximal strength based on the bench press and latissimus dorsi pull down exercise.
    • They also performed repeated repetitions at 80% of their maximum weight (as measured in phase 1) until exhaustion.
    • They then underwent a 30-second Wingate test (used to measure short-term power in athletes) to determine peak anaerobic cycling power, average power, and fatigue.

    And, the results.

    • The participants reported increased alertness and enhanced mood after caffeine and ephedra.
    • But, there were no significant differences between any of the treatments in muscle strength, muscle endurance, or peak anaerobic power.

    The bottom line?
    The authors concluded, “The results do not support the contention that supplementation with ephedra or caffeine will enhance either muscle strength or anaerobic exercise performance.”

    Interesting. Although an earlier study (also by Australian researchers) reported improved endurance with caffeine given as a single dose and references lots of other positive studies.
