Christensen, B., Stastny, S., Hilgers, S., Okamatsu, H., Manikowske, T., Youd, L., & Champa, J. (2011). Does creatine supplementation along with a resistance training program improve strength in women? Medicine and Science in Sports and Exercise, 43(5). Supplement abstract 2959.

This study assessed if creatine supplementation in women would significantly increase strength. Female adults (N = 62) ranging in age from 20 to 67 years were divided into groups. Forty-three Ss were randomly assigned to receive creatine or placebo capsules. Nineteen Ss who did not participate in the training program acted as controls. The placebo capsules were similar to the creatine capsules in appearance. Ss in the creatine group completed a loading dose of 16.8 g for five days followed by 0.045 g/kg/day maintenance dose. The placebo group took an equivalent amount of cornstarch capsules. Ss completed pre-testing and post-testing in a 3 RM bench press and squat. Ss completed a 12-week resistance training program that involved exercises for all the major muscle groups.

Significant differences were found between the placebo and the control group in the bench press and squat. No significant differences were found between the creatine and placebo groups in the in either strength test.

Implication. Creatine and placebo had similar effects on women when taken in conjunction with a strength training program. Females involved with a resistance-training program significantly increased strength when compared to a no-participation control group.
