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 flexor endurance by 33.4 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 during arm immobilization reduces the loss of elbow flexor endurance by 33.4 percentage points 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 flexor endurance by 33.4 percentage points compared to placebo, preserving muscular fatigue resistance during disuse.
Creatine fills muscle cells with a special energy reserve that quickly recharges the fuel used for muscle contractions. When the arm is immobilized and muscles are not used, this reserve keeps the muscles working longer before they tire, preventing the usual drop in endurance.
What the research says
1 studyWhen young men had their arm stuck in a cast for a week, those who took creatine lost much less arm endurance than those who took a sugar pill—exactly as the claim says. Creatine helped them keep their arm strength better.
