Summary

Creatine supplementation boosts maximal strength in young men undergoing resistance training, increasing weight lifted in bench press and squats. However, its effectiveness and safety in other populations and for different exercises remain unproven.

Area of Science:

  • Sports Science and Nutrition
  • Exercise Physiology
  • Nutritional Supplementation

Background:

  • Creatine is a widely used nutritional supplement among athletes.
  • Understanding its impact on strength and power is crucial for athletic performance and health.
  • Existing literature requires synthesis to clarify creatine's ergogenic effects.

Purpose of the Study:

  • To investigate the effects of oral creatine supplementation on maximal strength and power.
  • To analyze the impact on healthy adult populations.
  • To determine if creatine enhances specific strength and power metrics.

Main Methods:

  • Systematic meta-analysis of randomized or matched placebo-controlled trials.
  • Searched MEDLINE and Cochrane Controlled Trials Register up to June 2001.

  • Measured changes in maximal weight lifted, cycle ergometry sprint peak power, and isokinetic dynamometer peak torque.

    • Main Results:

    • Sixteen studies included in the meta-analysis.
    • Creatine supplementation significantly increased maximal weight lifted (bench press: +6.85 kg, squats: +9.76 kg) in young men engaged in resistance training.
    • No significant improvements were observed in arm curl strength, cycle ergometer performance, or isokinetic dynamometer peak torque.

    Conclusions:

    • Oral creatine combined with resistance training enhances maximal weight lifted in young men.
    • Evidence does not support improved performance in older individuals, women, or for other strength/power exercises.
    • The long-term safety of creatine supplementation remains unproven, precluding universal recommendation.
