Davis, J. C., Coughlin, M., Keys, S., & Paolone, V. J., (2003). Short-term creatine supplementation: Effects on metabolic rate and respiratory exchange ratio. Medicine and Science in Sports and Exercise, 35(5), Supplement abstract 1384.

Ss (N = 7) consumed 5 gm/day of either creatine or placebo for five days. Tests were for body mass, resting metabolic rate, respiratory exchange ratio, and glycerol concentration in the blood.

Body mass increased significantly in the creatine group. No significant differences were found in any of the other factors.

Implication. Short-term creatine supplementation produces an increase in body mass but does not differentially affect resting metabolic rate, respiratory exchange ratio, and glycerol concentration in the blood.
