Effects of A-GPC on Reaction Time and Cognitive Function
Completed · Not applicable · Has a placebo group
Conditions studied: Cognitive Change, Reaction Time
In brief
This is a randomized, double blind, crossover design study which measures the effect of alpha-glycerylphosphorylcholine (A-GPC) on reaction time and cognitive function in non-resistance trained males and females. Participants will complete baseline testing and then be randomized into one of two crossover treatments. Participants will report to the lab for five consecutive days whilst only getting a maximum of five hours of sleep per night from Monday through Thursday night. Once testing is complete on Friday, participants will receive a one week washout period then return to complete the opposite treatment.
