The Claim

In healthy, trained young adults undergoing 12 weeks of resistance training, creatine supplementation (administered daily or on training days only) had no statistically significant effect on isometric mid-thigh pull strength.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Among healthy, trained young adults who performed 12 weeks of resistance training, taking creatine daily or only on training days did not increase maximal force production during an isometric mid-thigh pull.

See the scientific wording

In healthy, trained young adults performing 12 weeks of resistance training, creatine supplementation (daily or training-day-only) did not significantly improve isometric mid-thigh pull strength, suggesting creatine may not enhance maximal force production in compound pulling movements under these conditions.

Why this might work

In trained people, muscles already have as much creatine as they can hold, so adding more doesn't make them produce more force. The nerves that tell muscles to contract don't fire more strongly, and the muscle fibers don't generate extra power during a hard pull.

  1. Study: Creatine monohydrate ingested daily compared to only on training days on body composition, muscle thickness, and strength after 12 weeks of resistance training: preliminary results

    People who took creatine while doing weight training didn’t get any stronger at pulling a heavy bar off the ground, even though some of their muscles got a little bigger. So, creatine didn’t help them pull harder.
