Although college students’ caffeine consumption has increased over the last decade, studies have not yet determined the time frame in which caffeine exerts its effects nor the impact of the vehicle by which caffeine is consumed. Sixty college students were randomly divided into one placebo (flour) and three caffeine treatment groups: 5-Hour Energy ®, Starbucks DoubleShot ®, or caffeine powder; all dosed at 3 mg caffeine/kg of body weight.  A battery of tests was performed prior to dosing and… Expand
Effects of Caffeine and Acute Aerobic Exercise on Working Memory and Caffeine Withdrawal
TLDR
Acute moderate intensity aerobic exercise and caffeine significantly improved WM accuracy and reduced CWS comparably and WM performance was not reduced following caffeine deprivation. Expand
A randomized, placebo-controlled crossover trial of a decaffeinated energy drink shows no significant acute effect on mental energy.
TLDR
There is strong evidence that the energy drink is not efficacious in enhancing s-energy levels, nor any related cognitive or behavioral variables measured, which suggests that labeling and marketing of some products which claim to provide these benefits may be unsubstantiated. Expand
An intervention study on the effect of matcha tea, in drink and snack bar formats, on mood and cognitive performance.
TLDR
It is suggested that matcha tea consumed in a realistic dose can induce slight effects on speed of attention and episodic secondary memory to a low degree. Expand
Investigating the effects of caffeine on executive functions using traditional Stroop and a new ecologically-valid virtual reality task, the Jansari assessment of Executive Functions (JEF©)
TLDR
The ability of JEF(©) to detect the effects of caffeine across a number of executive functioning constructs, which weren't shown in the Stroop task are demonstrated, suggesting executive functioning improvements as a result of a 'typical' dose of caffeine may only be detected by the use of more real-world, ecologically valid tasks.

Caffeine Intake Habits and the Perception of Its Effects on Health Among College Students
TLDR
In conclusion, college students are aware of the negative effects of caffeine, yet 75% consumed one or more and some exceeding five servings daily. Expand
Cardiovascular and Autonomic Responses to Energy Drinks—Clinical Implications
TLDR
There is an increasing consumption of energy drinks both in the United States and worldwide and it is likely that these cardiovascular outcomes are triggered by the hemodynamic, autonomic, and electrocardiographic responses to energy drink consumption. Expand
Caffeine-supplemented diet modulates oxidative stress markers and improves locomotor behavior in the lobster cockroach Nauphoeta cinerea.
TLDR
The results indicate that long-term caffeine supplementation may exert preventive effects against oxidative stress and support the use of N. cinerea as an efficient alternative model to assess the efficacy of food molecules. Expand
Sensation Seeking and Conscientiousness in Relation to Caffeine Consumption and Expectancy
Habitual caffeine consumers often report difficulty reducing caffeine use with many continuing to use caffeine despite experiencing symptoms suggestive of substance dependence. Given the evidence ofExpand
Analysing the EEG Signal Effectiveness of Chiang Rai Arabica Drip Coffee on Individual Human Brainwave
TLDR
The experimental result showed that coffee can make human brain wave (attention) increase and confirmed that coffee has a direct impact on personal Beta waves. Expand
Development of an improved isocratic hplc method for the determination of gallic acid, caffeine and catechins in tea
A simple and sensitive reversed phase high performance liquid chromatographic (HPLC) method has been developed for the determination of biomolecules in different types of tea. Most of the HighExpand

Time for tea: mood, blood pressure and cognitive performance effects of caffeine and theanine administered alone and together
TLDR
Evidence suggests that theanine is a physiologically and behaviourally active compound and, while it is unclear how its effects might explain perceived differences between tea and coffee, evidence suggests that it may be useful for reducing raised blood pressure. Expand
Effects of caffeine on mood and memory
  • W. H. Loke
  • Psychology, Medicine
  • Physiology & Behavior
  • 1988
TLDR
Caffeine decreased boredom and relaxation, and increased other ratings of subjective moods--anxiousness, tenseness, and nervousness, and high-to-moderate users of caffeine recalled more words than low users, particularly at the beginning of the lists. Expand
Mood and Cognitive Performance Effects of "Energy" Drink Constituents: Caffeine, Glucose and Carbonation
TLDR
Caffeine was found to be the main ED constituent responsible for the effects found, with possible minor, relatively weak effects of carbohydrates, and EDs were found to improve and/or maintain mood and performance during fatiguing and cognitively demanding tasks relative to placebo. Expand
Cognitive and physiological effects of an “energy drink”: an evaluation of the whole drink and of glucose, caffeine and herbal flavouring fractions
TLDR
There is some degree of synergy between the cognition-modulating effects of glucose and caffeine which merits further investigation, and the whole drink resulted in significantly improved performance on “secondary memory” and “speed of attention” factors. Expand
Effects of Morning Caffeine’ Ingestion on Mood States, Simple Reaction Time, and Short-Term Maximal Performance on Elite Judoists
TLDR
It is suggested that morning caffeine ingestion has ergogenic properties with the potential to benefit performance, increase anxiety and vigor, and decrease the simple reaction time. Expand
Effects of dietary caffeine on EEG, performance and mood when rested and sleep restricted
TLDR
The findings do not support the use of caffeine as a means for enhancing human function or as an antidote to the negative effects of sleep loss, and no evidence was found of net restorative effects of caffeine for any outcome variables. Expand
The effect of energy drinks on cortisol levels, cognition and mood during a fire-fighting exercise
TLDR
In situations of stress combined with physical performance, administration of an energy drink containing glucose and caffeine might be an easy to implement and cost effective way to maintain mental performance levels and to ameliorate the negative effects of stress on mood. Expand
Differential cognitive effects of energy drink ingredients: Caffeine, taurine, and glucose
TLDR
Caffeine, not taurine or glucose, is likely responsible for reported changes in cognitive performance following consumption of energy drinks, especially in caffeine-withdrawn habitual caffeine consumers. Expand
Effects of time-of-day and caffeine ingestion on mood states, simple reaction time, and short-term maximal performance in elite judoists
TLDR
Caffeine ingestion is recommended in the morning to minimize the diurnal fluctuations of short-term maximal performance and increase the chances of success in the Wingate test. Expand
Caffeine can decrease subjective energy depending on the vehicle with which it is consumed and when it is measured
TLDR
Caffeine, irrespective of vehicle, resulted in better memory, quicker reaction times in the choice reaction time test and the working memory task, and better and quicker responses with the vigilance task. Expand
