Caffeine
Conditions
Brief summary
The aim of the research project is to determine the changes in motivation to perform mental and physical tasks, feelings of vigor and fatigue, mental task vigilance and fine motor function after consumption of a commercially available energy product. The purpose of this study is determine whether e+shot, a product containing natural caffeine, will impact mood and performance up to 108 minutes post consumption compared to a sweetened solution containing synthetic caffeine.
Detailed description
Enrolled participants who are low consumers of caffeine will be administered either a placebo (3mg caffeine), caffeinated placebo (\ 100mg of caffeine) or e+shot first and then will be crossed over to receive the other two interventions. The study consists of 3 treatment periods of 108 minutes each with a washout period of 48 hours.
Interventions
DIETARY_SUPPLEMENTIntervention/treatment
Subjects received all 3 interventions Placebo \ 3mg caffeine Caffeinated placebo \ 100mg caffeine E+shots- The 4oz adaptogen-rich (E+shots) was E+ Shots (Isagenix International, LLC) containing approximately 90mg caffeine from green tea Camellia sinesis leaf extract (50%) and yerba maté extract (25%) along with a proprietary blend of adaptogenic herbs, including: eleutherococcus senticosus, crateagus oxycantha, rhodiola rosea and Schisandra chinensis.

Change in Fine Motor Task Performance
9-hole peg test- measured in seconds- The validated nine-hole peg test of finger dexterity was used to measure fine motor control. The 12 cm × 12 cm wooden pegboard contained nine holes and was placed on the desktop in front of the seated participant. There were nine 0.64 cm wide cylindrical pegs, were placed on the desktop outside of the container on the right side of the board and on the left side of the board for when the participant's right hand and left hand were tested, respectively. Participants were instructed to place one peg at a time into the pegboard holes until they were filled, and then remove each peg one at a time onto the desktop as fast as they could, first with their dominant hand and next with their non-dominant hand. Each test was performed twice.
