Detailed Description
In this study, we hypothesized that consumption of a dietary supplement containing extracts of American ginseng, bacopa monnieri and coffee fruit will improve reaction time and short-term memory in a population of highly trained athletes.
In order to test this hypothesis, we will employ a randomized, double blind, placebo controlled, parallel arm study design. 40-50 subjects will be recruited and randomized in a 1:1 ratio to either of two interventions:
Placebo: consumption of the placebo tablet Treatment: consumption of the supplement (treatment) tablet
On the day of the study, subjects will perform a series of reaction time tasks specific to the upper (i.e., arms) and lower (i.e., legs) body. They will also be asked to perform the stroop test. At the conclusion of baseline testing, subjects will consume either the placebo or treatment tablet. One hour later, the subjects will repeat all reaction time tasks as well as the stroop test. Differences in reaction time, as well as the error rate within each reaction time or stroop test, will serve as the primary endpoint. The data will then be analyzed to determine if there is a difference in the before and after reaction times and error rates between subjects on treatment and those consuming the placebo tablets.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Dietary supplement intervention
Participants were treated with 2 tablets containing extracts of American ginseng, bacopa monnieri and coffee fruit
|
Participants received and consumed 2 treatment tablets immediately following baseline testing, and one hour prior to post-treatment testing.
Each tablet contained extracts of Bacopa monnieri (150 mg), Coffea arabica (50 mg), and Panax quinquefolius L. (50 mg)

Placebo Comparator: Placebo Treatment
Participants received 2 placebo tablets containing microcrystalline cellulose.
The size, shape and appearance of the placebo tablet is identical to the treatment tablet.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Reaction time
Time Frame: One hour
|
Participants will perform a series of reaction time tasks prior to and after consumption of either the treatment or placebo tablets.
Reaction times will be quantified and analyzed to determine if the intervention affected these measures.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Stroop test
Time Frame: One hour
|
Participants are asked to identify the font color of a word (i.e., red, blue, green, yellow) by pressing a specific key on the keyboard when the word appears on a computer screen.
In situation #1, the font color of the word matches the written word (congruent test).
In situation #2, the font color does not match the written word (incongruent test).
