Summary

This study was designed to determine if a dietary supplement containing extracts of American ginseng, bacopa monnieri and coffee fruit can enhance cognitive performance in a population of trained athletes.

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.

Conditions

• Reaction Time

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Treatment (CopaPrime+ (USANA Health Sciences)	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)
OTHER	Placebo	Participants received and consumed 2 placebo tablets immediately following baseline testing, and one hour prior to post-treatment testing. Each tablet contained microcrystalline cellulose. The size, shape and appearance of the placebo tablet was identical to the treatment tablet.
