The Claim

Creatine supplementation at a dosage of 3 g/day for 14 weeks has no significant effect on hip range of motion or bilateral hip flexion strength in amateur soccer players when compared to placebo.

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 plain English

Taking 3 grams of creatine daily for 14 weeks does not change hip flexibility or hip strength in amateur soccer players compared to taking a placebo.

See the scientific wording

Creatine supplementation (3 g/day for 14 weeks) does not significantly improve hip range of motion or bilateral hip flexion strength in amateur soccer players compared to placebo.

Why this might work

Creatine increases the storage of a high-energy molecule in muscles, which quickly replenishes the fuel used during short bursts of intense activity. This allows muscles to produce more force for longer without tiring, improving strength and power in movements like jumping or sprinting, but it does not change how stretchy or flexible the hip muscles are or how strongly they contract during slow, controlled movements.

  1. Study: Effectiveness of a soccer injury prevention program based on creatine supplementation and internal load monitoring: a randomized controlled pilot study

    The study measured hip mobility and strength bilaterally and found no statistically significant changes in hip flexion or range of motion between creatine and placebo groups, indicating no effect on these specific parameters.
