Study Summary
This is a cross-over design study in which subjects arrived to the lab and were assigned a supplement to ingest. Prior to ingestion subjects completed baseline reaction time testing along with a questionnaire. Thirty minutes after ingestion subjects filled out the same questionnaire, completed a reaction time test, followed by a series of dynamic exercises. After the last exercise was finished subjects filled out the questionnaire, completed another reaction time test and repeated the series of dynamic exercises. Following the exercises, subjects filled out the questionnaire and completed a fourth round of reaction time testing. In total subjects would complete 2 rounds of dynamic exercises and 4 rounds of reaction time testing with heart rate being recorded before and after the dynamic exercise rounds. Subjects were told to wash-out for 7 days and return to the lab to complete the same testing but on the alternative supplement.
Primary Outcome
The primary purpose of this investigation is to determine if acute ingestion of a proprietary supplement containing caffeine, theanine, and tyrosine has any positive effects on markers of reaction time in athletic populations.
