Hulver, M. W., Campbell, A., Haff, G., Schroeder, C., Comeau, M., & Potteiger, J. A. (2000). The effects of creatine supplementation on total body fluids, performance, and muscle cramping during exercise. Medicine and Science in Sports and Exercise, 32(5), Supplement abstract 546.

The effects of six days of creatine supplementation were evaluated when exercising in the heat. Males (N = 18) were matched and assigned to a creatine or placebo group. The creatine dose was 3 gm/kg/d. A repeated sprint protocol on a cycle ergometer was performed in 30 degrees Celsius ambient temperature.

Creatine supplementation was associated with higher maintenance of peak and average power during repeated sprint performances and increased body mass. It did not alter total body fluids or cause muscle cramping.

Implication. Creatine supplementation improved repeated sprint performances and did not cause muscle cramping in hot conditions.
