Undergraduate Student Research Internships Conference

Caffeine is the most popular psychoactive substance in the world, with approximately 80% of the world’s adult population consuming some form of caffeine daily. Caffeine withdrawal is experienced by a large portion of caffeine consumers, with symptoms that include headache, decreased contentedness, and decreased alertness. Moreover, past literature has shown caffeine consumers’ experience mental fatigue following caffeine a 48-hour withdrawal period. However, it remains ambiguous what effect caffeine consumption has on the ability to withstand mental fatigue immediately following such a withdrawal period. Therefore, this study looked to explore the ability of caffeine to buffer the effects of mental fatigue …

The Effects Of A Multi-Ingredient Supplement On Various Cognitive Measures, Jason M. Curtis, Cassandra Evans, Veronica Mekhail, Paulina Czartoryski, Juan Carlos Santana, Jose Antonio

Journal for Sports Neuroscience

The purpose of this study was to investigate the effects of a multi-ingredient pre-workout supplement (MIPS) on mental and physical performance. Seventeen exercise-trained men (n = 7) and women (n=10) completed this randomized, placebo-controlled, double-blind, counterbalanced, crossover trial. Participants consumed either a multi-ingredient pre-workout supplement (MIPS) or a placebo in a randomized, counterbalanced order. Forty-five minutes post-consumption, the following assessments were conducted: psychomotor vigilance test (PVT), Profile of Mood States (POMS), Stroop test, vertical jump test, and a Cold pressor test. There was a one-week washout period between assessments. There were significant differences in the incongruent task for the Stroop …

The Effect Of Acute Caffeine Withdrawal On Exercise Performance In Habitual Caffeine Users, Timothy D. Griest

Masters Theses, 2020-current

Purpose: The purpose of this study was to investigate how exercise performance is impacted by acute withdrawal from caffeine (CAF) in habitual users and if CAF ingestion will reverse the negative impact of withdrawal or have a net positive benefit. Methods: Ten recreational cyclists (age 39.1 ± 14.9 y; VO_2max 54.2 ± 6.2 mL/kg/min) who were habitual CAF consumers (394 ± 146 mg/d) completed four trials, each consisting of peak isokinetic torque testing and a 10-km time trial (TT). On each trial day, subjects consumed either 1.5 mg/kg CAF to prevent withdrawal or placebo (PLA) 8 hours before their …
