Study snapshot

DesignRandomized double-blind placebo-controlled parallel trial
ModelHuman
Sample34 resistance-trained collegiate athletes
Intervention5 g creatine before training, 5 g after training, or placebo
Duration8 weeks
EndpointsFat-free mass; Body fat; Strength; Muscular endurance; Isometric pull

What the study showed, in plain terms

Direct randomized test of whether taking creatine immediately before or after training materially changes training adaptations.

Key findings

Training improved outcomes across groups, but taking creatine before versus after training did not produce an additional timing-specific advantage.

What this study can and cannot tell us

Small sample; athletes co-ingested protein and maltodextrin; not designed to compare daily creatine with no creatine over the full week.
