Creatine supplementation may enhance performance in high-intensity, short-term exercise by increasing muscle creatine stores. Short-term use appears safe, with potential for increased muscle mass with chronic use and resistance training.

Area of Science:

  • Nutritional Biochemistry
  • Exercise Physiology

Context:

  • Creatine is a naturally occurring nutrient found in animal foods.
  • It plays a role in cellular energy production, particularly in the ATP-CP system.
  • Recent research investigates its ergogenic potential in sports performance.

Purpose:

  • To evaluate the efficacy of creatine supplementation as an ergogenic aid.
  • To assess the impact of creatine on exercise performance and body composition.
  • To examine the safety profile of creatine supplementation.

Summary:

  • Oral creatine monohydrate supplementation increases muscle total creatine, including free creatine and phosphocreatine.
  • Many studies indicate enhanced performance in high-intensity, short-term exercise reliant on the ATP-CP system.

  • Supplementation may lead to increased body mass, initially due to water retention, and potentially muscle mass with chronic use and resistance training.

    • Impact:

    • Creatine supplementation appears to be a safe ergogenic aid for short-term, high-intensity exercise.
    • Further research is needed to confirm the effects on muscle mass with chronic supplementation.
    • Individual athletes may consider creatine for performance enhancement, weighing potential benefits against available data.
