Effects of A-GPC on Reaction Time & Cognitive Function

Status Completed

Clinical Trial Summary

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.

Clinical Trial Description

Subjects expressing interest in doing the study will be interviewed in the UMHB Human Performance Lab (HPL) to determine whether they qualify to participate in the study. Upon qualification, participants will be scheduled a familiarization session in which participants will be taught how to use the Makoto Arena, a reaction time machine. Participants will then schedule their first testing session which will include: questionnaires, hemodynamic measures, reaction time testing, cognitive function testing via ImPACT, an acute exercise bout, reaction time testing, and cognitive function testing via ImPACT. Participants will then be randomized into one of two treatments. Supplementation protocol: Participants will be randomly assigned into one of two treatments and will be given 4oz of either a placebo or active treatment mixed in orange flavored Gatorade everyday for 5 days. On Monday, participants will consume the beverage after testing is complete. Tuesday through Friday the beverage will be consumed as the participants arrive in the HPL. On Mondays and Fridays, testing will be as follows: questionnaires, hemodynamic measures, reaction time testing, cognitive function testing via ImPACT, an acute exercise bout, reaction time testing, and cognitive function testing via ImPACT. On Tuesdays and Thursdays, participants will come check into the HPL for 30 minutes. On Wednesday, participants will come into the HPL to complete the acute exercise bout. To control their sleep to the best of our ability, participants are required to send emails every 30 minutes beginning at 10pm until their designated sleep time so the investigators know the participants are not asleep and gaining more than 5 hours of sleep. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
