| Summary: | Objective: The purpose of this study was to determine the effect of caffeine, as introduced by a popular energy drink, on neurocognitive function. Methods: Twenty-four male participants, 18-28 yrs old, completed two days of testing: baseline and post-consumption testing. Exactly 48-hours separated the two sessions. During the second day of testing, participants received treatment or control drink and waited 90 minutes before performing the ImPACT for post-consumption data. Results: Verbal Memory: (F[1, 22]=0.69, p=.416, η2=.03) Visual Memory:(F[1,22]=1.31, p=.264, n2=.056) Visual Motor Speed:(F[1,22]=.660, p=.425, n2=.029) Reaction Time: (F[1,22]=.015, p=.903, n2=.001) Impulse Control: (F[1,22]=.453, p=.508, n2=.020) Conclusions: Researchers determined caffeine from an energy drink, consumed 90 minutes prior to ImPACT baseline testing has no statistically significant effect on ImPACT composite scores compared to control group. Therefore, caffeine does not appear to be an obstacle for clinicians when assessing composite scores of ImPACT. === NDSU Athletic Training Program Faculty; NDSU HNES Department
