Can creatine help your muscles bounce back after injury?

Returning to exercise after an injury can be frustrating. Your usual weights feel heavier, and the muscles you’ve worked hard to build may look and feel different. This is normal – regaining strength takes time – but can anything help speed up this process?

A new systematic review examines whether creatine can promote muscle recovery after periods of inactivity, particularly when people return to exercise. Here’s what they found.

About the exam

Creatine is a compound stored in your muscles that helps produce energy during short, intense activities like weightlifting.

It is well known for supporting muscle strength and growth, but researchers wanted to know if it could also help people rebuild their muscles after immobilization from an injury.

They looked at six randomized, placebo-controlled trials involving 118 participants, most of whom were aged 15 to 24. Studies have looked at creatine monohydrate supplementation during one to two weeks of immobilization and, in some cases, the rehabilitation period that followed.

Creatine helped support muscle recovery during rehabilitation

When participants returned to resistance training after injury, creatine supplementation was associated with greater improvements in several measures of muscle recovery.

Compared to those taking a placebo, participants taking creatine saw greater increases in quadriceps size, lower body lean mass, and power output upon returning to the gym. One trial also found better endurance recovery and similar strength improvements between groups.

During periods of immobilization, some studies suggested that creatine helped preserve lean mass, but the benefits were less consistent.

Larger studies are needed to confirm these findings, but the findings offer encouraging insight into the potential role of creatine in rehabilitation.

Why Creatine May Work Better With Strength Training

Creatine appears to be most helpful when muscles are re-used through exercise. This is because creatine helps your muscles replenish ATP, a molecule that provides the energy needed to contract during exercise. When you lift weights, your muscles use ATP to fuel each repetition.

Strength training also triggers muscle repair and growth. By helping to provide energy during exercise, creatine can support these processes as your muscles adapt and regain strength.

Simply put, creatine showed greater benefits when participants returned to training, because creatine has more opportunity to help your muscles when they’re actively working.

How to support your return to strength training

If you’re recovering from an injury or surgery, rebuilding muscle takes time.

Once cleared by your healthcare professional, return to resistance training by starting with manageable weights and gradually increasing the challenge. This is called progressive overload and helps your muscles adapt as they gain strength.

It may also be helpful to discuss creatine monohydrate with your doctor as part of your rehabilitation plan. But remember, this research suggests its potential benefits are most relevant once you’re actively rebuilding muscle.

Takeaways

Creatine has the potential to be a great ally for your rehabilitation routine. When combined with resistance training, it can promote an increase in muscle size, strength and power. Think of it as a way to provide a little extra support when you return.
