Head, B. J., Womack, J. W., Parker, A. G., Green, J. S., & Crouse, S. F. (2006). Effect of creatine supplementation on lactate levels following intense, anaerobic exercise. Medicine and Science in Sports and Exercise, 38(5), Supplement abstract 2253.

This study determined the effect of creatine supplementation on lactate levels following high intensity, anaerobic exercise. Ss (N = 44) performed a 30-second Wingate cycle ergometry test. This was followed by three 30-second cycle sprints at 50% of peak power with 2 minutes recovery between exercise bouts. Blood lactate levels were measured before, 5 minutes post, and 10 minutes post exercise. Ss were then assigned randomly to supplement for 5 days with either 20 gm/day of creatine monohydrate (M = 11; F = 11) or a sucrose placebo (M = 8; F = 14). Following the supplementation regimen, the exercise bouts and lactate measurement procedures were repeated.

No significant effects were recorded.

Implication. Short-term creatine supplementation did not affect lactate production following high intensity anaerobic exercise.
