The Claim
In young, healthy men aged 18–25, daily supplementation with 20 grams of creatine monohydrate during one week of upper-limb immobilization reduces the decline in elbow extensor endurance by 28.5 percentage points compared to placebo, preserving muscular fatigue resistance during disuse.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In young healthy men aged 18–25, taking 20 grams of creatine monohydrate daily for one week while the arm is immobilized results in a 28.5 percentage point smaller reduction in elbow extensor endurance compared to taking a placebo.
See the scientific wording
In young, healthy men aged 18–25, daily supplementation with 20 grams of creatine monohydrate during one week of upper-limb immobilization likely reduces the decline in elbow extensor endurance by 28.5 percentage points compared to placebo, preserving muscular fatigue resistance during disuse.
Creatine builds up in muscle cells and helps make more energy quickly when muscles work, which keeps them from getting tired fast. It also signals the muscle to make more proteins and add more nuclei, helping the muscle stay strong even when it's not being used.
What the research says
1 studyWhen young men had their arm stuck in a cast for a week, those who took creatine every day lost much less arm strength and endurance than those who took a sugar pill—specifically, creatine helped them keep about 28% more of their endurance than the placebo group.
