Effects of Creatine on Sprint Time and Body Composition of Division III Baseball Players
Dr. Kevin Cole, Hope College
Taking creatine as an ergogenic aid may help to increase performance in anaerobic activities such as sprinting. Theoretically, creatine supplementation improves performance by increasing the amount of creatine phosphate allowing more fuel for ATP production that enables the body to produce more energy at a higher rate. This study was designed to determine if taking creatine as a supplement (CRE, n=4) when coupled with a six week speed training regimen performed 3 times per week would result in a greater decrease in 60 yard dash time when compared with only performing the 6 week speed training regimen (CON, n=4). It was hypothesized that over the six week training period the creatine group would improve on their sixty yard sprint times while increasing their lean body mass. Following the six-week training period, body mass in the creatine group increased significantly (M= 2.97kg, +/- .94kg, p= 0.008). No significant difference was found in the control group. Body composition for the creatine group significantly increased (M=2.55%, +/- 1.51%, p=0.044) while no significant difference was seen in the control group. There were no significant differences between 60 yard sprint times in the creatine group or the control group. There was no evidence that creatine increased lean body mass or improved performance in the 60 yard dash.
