Energy Drinks Clinical Trial
Official title:
A Test of the Effects of Energy Drinks
This study is designed to test the efficacy of energy drinks. This is a double-blinded, crossover, randomized clinical trial, measuring the effect of the test drinks compared with placebo drink in 200 participants aged 18-70 years.
This study is designed to test the efficacy of an energy drink compared to placebo via a
double-blind, crossover, randomized clinical trial. Energy levels will be assessed before and
after consumption of the test beverages on 2 days separated by a week in 200 participants
aged 18-70 years. The study is crossover because the participants will be (randomly)
receiving one drink on Test Day 1 and the other drink on Test Day 2.
After signing written informed consent, participants will be fed a light lunch, and their
pulse, weight and height measured. A baseline battery of computer-based tests to assess
energy levels will be conducted. These computer-based measures will take ~40 minutes to
complete and will include: a) a long-term memory test b) a Profile of Mood States (POMS2)
brief form; c) Rapid Visual Information Processing (RVIP) test, d) The N-Back Task; d)
Reaction time online test; f) the Flanker Task. Participants will then be asked to fill out a
baseline survey (30 min), with questions about current health-related behaviors, specifically
questions about physical activity and diet.
Upon completing the baseline battery (survey administered at test session 1 only),
participants will be randomly administered the energy drink or the placebo to consume while
observed. Subsequently, the battery of computer-based tests to assess energy levels will be
re-administered 30 minutes, 2.5 hours and 5 hours after consumption of the test drink.
The study intervention will be double-blinded: participants will be blinded to whether they
are receiving the active or the placebo drink, and study team members will also not be aware
of the assignment.
When the study ends, full compensation will be given if the intervention is fully completed;
if the intervention is not fully completed, partial compensation will be given.
