• How does creatine affect muscle growth?

  • Sources:

    Creatine significantly impacts muscle growth through several mechanisms:

    Mechanisms of Action

    1. Phosphocreatine System: Creatine increases the concentration of phosphocreatine in muscles, providing a quick source of energy for high-intensity activities. This leads to improved performance in activities like sprinting and weightlifting, thereby facilitating greater muscle stress and growth 1.

    2. Increased Water Retention: Creatine draws water into muscle cells, enhancing cell hydration. This not only contributes to muscle size (temporary water weight) but may also promote protein synthesis, encouraging muscle growth 2 3.

    3. Enhanced Performance: Research shows that creatine can increase overall power output, which may range from 1% to 20%, depending on the exercise type. Improved performance allows for more effective training sessions, leading to muscle hypertrophy over time 1.

    4. Reduced Fatigue: It has been demonstrated that creatine supplementation can reduce muscle fatigue, allowing for longer and more intense workouts that contribute to muscle growth 1 2.

    5. Hormonal Effects: Creatine may influence hormonal levels, such as increasing dihydrotestosterone (DHT), indirectly supporting muscle growth and strength through enhanced hormonal balance 3.

    Practical Recommendations

    • Dosage: Typical supplementation is around 3-5 grams per day for maintenance, with higher doses (10-15 grams) potentially beneficial for heavier individuals. This supplementation is generally safe and can yield significant benefits for muscle growth and overall performance 1 4.

    In summary, creatine enhances muscle growth primarily through improved energy availability, hydration effects, and better performance during resistance training. This compound not only supports muscle size and strength but can also have cognitive benefits and improve recovery 2. Always consult a healthcare professional before starting any supplementation.
