The present study investigated the relationship between masculinity ideology, outcome expectations, energy drink use, and sleep disturbances. METHOD The authors recruited 467 adult males from universities and the Internet who provided data on their endorsement of traditional mascul...

Energy drink use has grown despite limited research to support efficacy or safety and amid concerns when combined with exercise. The purpose of this study was to assess the effects of 10 weeks of once-daily energy drink consumption or energy drink consumption with exercise on measures of body composition, cardiorespiratory fitness, strength, mood, and safety in previously sedentary males. Thirt...

There has been a dramatic rise in the consumption of glucose energy drinks (e.g., Amp, Monster, and Red Bull) in the past decade, particularly among high school and college students. However, little laboratory research has examined the acute objective and subjective effects of energy drinks. The purpose of this study was to investigate the acute effects of a glucose energy drink (Red Bull) on c...

BACKGROUND To investigate the effects of a caffeine-containing energy drink on soccer performance during a simulated game. A second purpose was to assess the post-exercise urine caffeine concentration derived from the energy drink intake. METHODOLOGY/PRINCIPAL FINDINGS Nineteen semiprofessional soccer players ingested 630 ± 52 mL of a commercially available energy drink (sugar-free Red Bull®)...

BACKGROUND Energy drink consumption has been anecdotally linked with sudden cardiac death and, more recently, myocardial infarction. As myocardial infarction is strongly associated with both platelet and endothelial dysfunction, we tested the hypothesis that energy drink consumption alters platelet and endothelial function. METHODS Fifty healthy volunteers (34 male, aged 22+/-2 years) partici...

BACKGROUND There are popular reports on the combined use of alcohol and energy drinks (such as Red Bull and similar beverages, which contain caffeine, taurine, carbohydrates, etc.) to reduce the depressant effects of alcohol on central nervous system, but no controlled studies have been performed. The main purpose of this study was to verify the effects of alcohol, and alcohol combined with ene...

BACKGROUND A high incidence of dental caries and dental erosion associated with frequent consumption of soft drinks has been reported. The purpose of this study was to evaluate the pH response of dental plaque to a regular, diet and high energy drink. METHODOLOGY Twenty subjects were recruited for this study. All subjects were between the ages of 20 and 25 and had at least four restored tooth...

The use of caffeine containing energy drinks has dramatically increased in the last few years, especially in the sport context because of its reported ergogenic effect. The ingestion of low to moderate doses of caffeinated energy drinks has been associated with adverse side effects such as insomnia or increased nervousness. The aim of the present study was to assess psycho-physiological changes...

OBJECTIVE To review the effects, adverse consequences, and extent of energy drink consumption among children, adolescents, and young adults. METHODS We searched PubMed and Google using "energy drink," "sports drink," "guarana," "caffeine," "taurine," "ADHD," "diabetes," "children," "adolescents," "insulin," "eating disorders," and "poison control center" to identify articles related to energy...

BACKGROUND Well-known reports suggest that the use of energy drinks might reduce the intensity of the depressant effects of alcohol. However, there is little scientific evidence to support this hypothesis. OBJECTIVE AND METHODS The present study aimed at evaluating the effects of the simultaneous ingestion of an alcohol (vodka(37.5%v/v)) and an energy drink (Red Bull-3.57 mL/kg), compared wit...
