The Claim

Daily supplementation with 3 grams of creatine monohydrate for 14 weeks significantly improves isometric knee extension strength, hip extension strength, and countermovement jump height in amateur soccer players.

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.

Cause and effect
1 study reviewed
In plain English

Amateur soccer players who take 3 grams of creatine monohydrate every day for 14 weeks show measurable increases in isometric knee extension strength, hip extension strength, and jump height during countermovement jumps.

See the scientific wording

In amateur soccer players, daily supplementation with 3 grams of creatine monohydrate for 14 weeks significantly improves isometric knee extension, hip extension, and countermovement jump height, suggesting enhanced neuromuscular performance during high-intensity efforts.

Why this might work

Creatine enters muscle cells and gets converted into phosphocreatine, which quickly replenishes ATP when muscles work hard. This keeps energy levels high during short bursts of intense activity, allowing muscles to produce more force and resist fatigue, leading to stronger leg extensions and higher jumps.
