Multiple studies have been conducted on the effect of creatine monohydrate supplementation on muscular strength. However, evidence of the effect of creatine supplementation on anaerobic performance is less clear. PURPOSE: To determine if creatine supplementation impacts sprint speed and vertical jump height. METHODS: 10 females and 9 males (N=19) aged 21 ± 0 from the College of Saint Benedict and Saint John’s University participated in this randomized single blind study. Participants ingested creatine monohydrate or a placebo for 21 days and were tested on days 1, 6, 14, and 21. Day one tests were completed prior to the consumption of creatine or a placebo. Each test day participants completed three vertical jump tests and two 30-meter sprints. For both assessments the best result was used. RESULTS: Participants ingesting creatine were not found to have improved anaerobic performance within sprints or jumps compared to participants ingesting the placebo. There was a significant main effect of time (p = .039) found for sprint time with both groups combined. Simple main effects showed a significant decrease in sprint time in the treatment group (p < .05) however, no significance was found between the control and treatment groups (p = .091). There was not found to be a main effect of treatment (p = .402), time (p = .069), or treatment*time interaction (p = .423) for vertical jump height. CONCLUSION: Creatine supplementation significantly decreased sprint speed, however, there wasn’t a significant difference from the control group. Creatine supplementation did not significantly impact vertical jump height.
