Active men (N = 19) and women (N = 17) were formed into a creatine supplementation group (10 gm/d) or a placebo group. Treatment lasted 56 days.

The following were found:

• There were no gender differences for the treatments.

Implication. Creatine supplementation for 56 days only affected strength variables.
