Over the past few years, energy drink consumption has increased among students aged 18–34 years. Energy drinks alter the balance, reduce blood flow and interfere with neuromuscular activation in the lower extremities. We attempted to determine which specific additive of three different drinks (red bull, rockstar, and bang) could contribute to changes in muscle activation of the ankle complex. Twenty healthy young adults aged 22–28 years were included in this study and allocated among 3 groups, red bull, rockstar, and bang. Neuromuscular data were obtained from EMG sensors positioned on the anterior tibialis and gastrocnemius before completing the four balance tasks. Each participant completed all the tasks before and after the 16-ounce Edrink. ANOVA was performed to compare the data before and after the beverage. Statistical significance was set at P <0.05. A trend was observed in red bull and bang groups revealing a faster anterior tibial activity and prolong activation for gastrocnemius. The rockstar group also showed a more rapid activation trend and shorter response during all tasks for the gastrocnemius. It appears that the additives found in Redbull and Bang produce an increased posterior sway, indicated by the faster activity observed on the anterior tibial muscle. On the other hand, the elements encountered in rockstars provoke anterior movements, creating the need for a quicker response from the gastrocnemius muscle. Further research is required to explore certain energy drink ingredients' effects on dynamic activities such as walking.

Objetivo: O objetivo é analisar a variabilidade da frequência cardíaca em universitários saudáveis, após ingestão de bebida energética. Materiais e Métodos: Estudo prospectivo, uni-cego que incluiu indivíduos de coração normal. Todos submeteram-se à monitorização eletrocardiográfica por 5 minutos, antes da ingestão de 250 ml do energético Red Bull® (grupo A – GA) ou de placebo (grupo B – GB), numa relação 3:1, num período de 10 minutos. Após 45 minutos, um outro ECG foi realizado. Os indivíduos dos GA e GB permaneceram em repouso, sentados. Foi obtida a VFC antes e após a administração das substâncias, nos domínios do tempo (DT) e da frequência (DF). Foram excluídos consumidores de energéticos, aqueles que tivessem ingerido álcool ou cafeína nas 24 h antes da investigação. Resultados: Foram incluídos 30 indivíduos no grupo A (16H, 14M, média de idade 22±3a, variando entre 17 e 36 a) e 10 no grupo B (6H, 4M, média de idade 20±5a).  Não se observou variação da frequência cardíaca antes e após nos GA e GB (70±10 vs 71±8 no GA [p=0,941] e, 69±8 vs. 70±9 no GB[p=0,881]). Houve incremento significativo da atividade vagal no GA, em comparação ao GB, tanto no DT (SDNN e RMSSD), como no DF (HF). O Red Bull® interferiu pouco no sistema simpático e na relação LF/HF nos GA e GB. Conclusões: O Red Bull® na dose empregada, aumentou a VFC por incremento do tônus parassimpáticos; não causou alteração no equilíbrio autonômico (relação LF/HF); esses achados confirmam os efeitos da cafeína sobre a VFC demonstrado em outros estudos.Palavras-chave: Variabilidade da Frequência Cardíaca; Bebida Energética; ArritmiasABSTRACTObjective: The objective is to analyze the heart rate variability in college students after energy drink intake. Materials and Methods. Prospective study, uni-blind which included normal individuals. All the students underwent electrocardiographic monitoring for 5 minutes before ingestion of 250 ml of Red Bull® (group A - GA) or placebo (Group B - GB) in a 3: 1 ratio, in a 10-minute period. After 45 minutes, another ECG was performed. Individuals at GA and GB remained at rest, sitting. HRV was obtained before and after administration of the substances in the time domain (TD) and frequency domain (FD). Those students categorized as frequent consumers of energy drinks and those who have been drinking alcohol or caffeine in the 24 hours prior to investigation were excluded from the study.Results: Thirty  subjects were included in group A (16M, 14F, mean age 22 ± 3a, ranging between 17 and 36 a) and 10 in group B (6 H, 4M, mean age 20 ± 5a). There was no change in heart rate before and after ingestions in  GA and GB (70 ± 10 vs 71 ± 8 in GA [p = 0.941] and 69 ± 8 vs. 70 ± 9 in GB [p = 0.881]). There was a significant increase in vagal activity in GA compared to GB, both in TD (SDNN and RMSSD) as well as in the FD (HF). The Red bull® little interfered with the sympathetic system and the LF / HF ratio in GA and GB. Conclusions: The Red Bull increased HRV by increase in parasympathetic tone; caused no change in autonomic balance (LF / HF ratio); these findings confirm the effects of caffeine on HRV shown in other studies.Keywords: Heart Rate Variability; Energy Drinks; Arrhythmias

The relationship between risk-taking behavior, alcohol consumption and negative alcohol-related consequences is well known. The current analyses were conducted to investigate whether alcohol mixed with energy drink (AMED) is related to risk-taking behavior and if there is a relationship between the amount of energy drink mixed with alcohol consumed, risk-taking behavior and negative alcohol-related consequences. Data from N = 1276 AMED consuming students from the Netherlands, UK and Australia who completed the same survey were evaluated. The analysis revealed that, compared to AMED occasions, on alcohol only (AO) occasions significantly more alcohol was consumed and significantly more negative alcohol-related consequences were reported. On both AO and AMED occasions, there was a strong and positive relationship between amount of alcohol consumed, level of risk-taking behavior and number of reported negative alcohol-related consequences. In contrast, the level of risk-taking behavior was not clearly related to energy drink consumption. Across risk-taking levels, differences in the amount of energy drink consumed on AMED occasions did not exceed one 250 mL serving of energy drink. When correcting for the amount of alcohol consumed, there were no statistically significant differences in the number of energy drinks consumed on AMED occasions between the risk-taking groups. In conclusion, alcohol consumption is clearly related to risk-taking behavior and experiencing negative alcohol-related consequences. In contrast, energy drink intake was not related to level of risk-taking behavior and only weakly related to the number of experienced negative alcohol-related consequences.

Introduction: Energy drinks are presumed to enhance energy, physical endurance, mood, and boost metabolism. Serious health risks have been reported with energy drink consumption such as myocardial infarction, cardiac arrest, stroke, seizures, and arrhythmias. More than 20,000 emergency department visits related to energy drink consumption were reported in 2011. Little is known about the possible pathophysiological mechanisms and adverse events associated with energy drinks. Unlike the tobacco and alcohol industry, there are limited restrictions regulating the purchasing and marketing of these drinks. Purpose: To determine if consumption of energy drinks alter; vital signs (blood pressure, temperature), electrolytes (magnesium, potassium, calcium), activated bleeding time (ACT), or cardiac responses measured with a 12-lead electrocardiographic (ECG) Holter. Method: Subjects consumed two-16 ounce cans of an energy drink within one hour and remained in the lab where data was collected at base line (BL) and then during four hours post consumption (PC). Vital signs were taken every 30 minutes; blood samples were collected at BL, one, two and four hours PC and ECG data was collected throughout the entire study period. Paired students t-test and a corresponding non-parametric test (Wilcoxon signed rank) were used for analysis of the data. Results: Fourteen healthy young subjects were recruited (mean age 28.6 years). Systolic blood pressure (BL=132, ±7.83; PC= 151, ±11.21; p=.001); QTc interval (BL=423, ±22.74; PC=503, ±24.56; p<.001); magnesium level (BL 2.04, ± 0.09; PC=2.13, ±0.15; p=.05); and calcium level (BL=9.31, ±.28; PC=9.52, ±.22; p=.018) significantly increased from BL. While potassium and ACT fluctuated (increase and decrease) no significant changes were observed. Eight of the fourteen subjects (57%) developed a QTc >500 milliseconds PC. Conclusions: In our sample, consumption of energy drinks increased systolic blood pressure, serum magnesium and calcium, and resulted in repolarization abnormalities. Because these physiological responses can lead to arrhythmias and other abnormal cardiac responses, further study in a larger sample is needed to determine the effects and possible consequences of energy drink consumption.

Abstract Background Consumption of energy drinks has become an escalating global public health problem. The work schedule and irregular sleeping habits of commercial bus drivers make them highly susceptible to getting fatigued, hence most of them consume energy drinks as a fatigue management strategy. However, consumption of energy drinks produces numerous psychomotor side effects that if consumed among drivers puts the traveling public in danger of road accidents. This study sought to assess the prevalence of energy drink consumption and awareness of associated potential health problems among commercial long-distance bus drivers operating from the Ho municipality. Methods This was a cross-sectional study involving 132 participants who completed a structured questionnaire on the participants' socio-demographic characteristics, frequency of consumption and reasons for consumption. It also included questions to assess the knowledge of the ingredients and side effects of energy drinks. Results A majority (62.1%) of the drivers had more than 10 years of commercial driving experience. A 75% energy drink consumption prevalence was recorded with driving performance enhancement (78.8%) as the predominant reason for consumption. 7 - 10 bottles per week were consumed by most (32.2%) of the drivers with the most consumed brand being Rush energy drink (54.5%). Also, 72.0% had poor knowledge of the side effects linked with energy drink intake likewise the ingredients in them. Conclusion Energy drinks were consumed by the majority of the drivers at the Ho main bus terminal of which most of the drivers had poor knowledge of the potential health problems linked with the consumption of these drinks. The consumption of energy drinks was observed to be higher among the drivers with lower education levels, higher monthly income and those who worked long hours in a day. The Ghana National Road Safety Commission (GNRC) in collaboration with other private road transport unions in Ghana should organize regular seminars for commercial bus drivers on the potential dangers and effects associated with energy drink consumption.

Introduction: Energy drinks continue to be the fastest growing beverage market with sales expected to reach $60 billion in the next few years, yet have demonstrated adverse cardiovascular effects such as prolongation of the QTc interval on EKG. While QTc prolongation observed with certain drugs has long been used as an indicator of increased risk of torsade de pointes, recent data has identified the early repolarization interval J-T peak (JTp) as a more specific marker for proarrhythmic potential. Drugs that selectively block the human ether-a-go-go related (hERG) potassium ion channel prolong QTc by prolonging both early repolarization (JTp) and late repolarization (T peak -T end [Tpe] interval), and are associated with an increased risk of torsade. In contrast, drugs that additionally block inward late sodium and L-type calcium prolong QTc by prolonging Tpe but not JTp, and have demonstrated reduced risk of torsade. In 2018, the C-Energy-X study demonstrated QTc prolongation in 22 healthy subjects (mean age 28 ± 7yrs) who consumed energy drink while at rest and following short periods of exercise. Our study provides a secondary analysis of this data in terms of its effect on JTp, a potentially more specific marker for torsade risk. Methods: Using H-Scribe software, two evaluators independently measured JTp and RR intervals from C-Energy-X subjects pre- and post-energy drink consumption in the rest and exercise phases. Values were corrected for heart rate using the linear correction formula JTpc=JTp + 0.150(1-RR), where RR is R-to-R interval. Mean JTpc values from each phase were analyzed using a paired sample two-tailed t -test. Results: In the resting phase following energy drink consumption (PCr), there was a statistically significant increase in JTpc intervals for 77% of subjects by a mean of 10.5ms (baseline=234 ± 21.3ms; PCr=245 ± 22.0ms; p =0.015). In the exercise phase following energy drink consumption (PCe), 64% of subjects increased JTpc intervals by a mean of 0.8ms which was not significant (baseline=225 ± 15.7ms; PCe=226 ± 17.9ms; p =0.845). Conclusion: In the resting phase, energy drink consumption was associated with statistically significant prolongation of JTpc, suggesting a theoretical increased risk of torsade de pointes.

Objective. To quantify energy drink consumption and influences affecting consumption in those who participate in or watch extreme sports. Methods. An online survey, informed by focus groups, was administered via Quadrics®. Advertisement was via social media, emailing extreme sport clubs, flyers at extreme sport locations, and word of mouth. Participation was limited to those >18 y who watched and/or participated in extreme sports. The study was conducted in New Zealand, with international online availability. Variables measured comprised age, sex, energy drink consumption, reasons for their use, extreme sport viewing, advertising, and sponsorship. Logistic regression models were utilised. Results. Amongst participants who completed the questionnaire (n = 247), the mean (SD) age was 26.2 (8.2) y, 40.5% were female, 57.9% consumed energy drinks, and 25.5% consumed >one per week. For every year older, odds of consuming energy drinks were 3.1% lower p = 0.04 . A 31% increase in energy drink consumption for every single increase of viewing extreme sport per week was observed p = 0.009 ; however, reported viewing of advertising was not associated with increased consumption. Conclusions. A large proportion of extreme sport enthusiasts regularly consume energy drinks, especially younger adults. Extreme sport viewing, where energy drink sponsorship is common, appears to increase their consumption, even if not considered advertising by the viewers themselves.

The energy drink consumption habits of nurses working in clinical settings is unknown. Utilizing a descriptive-comparison design, researchers examined the caffeine and energy drink habits of clinical nurses and relationships or differences that existed with their sleep quantity, sleep quality, and perceived stress levels. Data were analyzed using descriptive and inferential statistics. Significant relationships existed between energy drink consumption and sleep quality, sleep quantity, and perceived stress levels. Nurses who consumed energy drinks had poorer sleep quality and fewer sleep hours compared with caffeine-only consumers and noncaffeine consumers. Nurses who consumed energy drinks also had increased levels of perceived stress than noncaffeine consumers. Educating nurses regarding energy drink ingredients and relationships that exist between energy drink consumption, sleep, and perceived stress could be beneficial. Future studies are needed to examine motivational factors related to energy drink consumption as well as any health or safety implications that might be associated.

Abstract Objectives This study assessed energy drink consumption and high-risk behaviors, including alcohol and drug use, cross-sectionally among participants in three cohort studies—the Nurses’ Health Study 3 (NHS 3), the Growing Up Today Study (GUTS) and GUTS2. Methods Questionnaires, including validated food-frequency questionnaires (FFQs), collected participant demographics, risky behavior, and energy drink consumption data. [The specific question used for energy drink intake read as follows: “Do you drink energy drinks, e.g., Red Bull, Rock Star, Monster (8 oz. can)?” for NHS3, 2010–2019; GUTS, 2011; and GUTS2, 2011.] Following descriptive analysis, multivariable-adjusted logistic regression estimated associations between energy drink consumption and odds of risky behaviors, including pooled odds-ratios (pORs) across all cohorts. Results Of the 46,390 participants this study assessed, ∼13% reported energy drink consumption at least monthly. Risky behaviors associated with energy drink consumption included smoking [pOR: 1.88 (95% CI 1.55–2.29)], having higher body mass index [pORs: 1.31 (95% CI 1.11–1.53) for overweight (25–30 kg/m2) and 1.67 (95% CI 1.34–2.08) for obesity (≥30 kg/m2) compared to &lt;25 kg/m2, respectively], insufficient sleep [pOR: 1.29 (95% CI 1.11–1.50) for &lt;7 hours compared to 7–9 hours], tanning bed use [pOR: 2.31 (95% CI 1.96–2.72)], binge drinking [pOR: 2.53 (95% CI 2.09–3.07)], marijuana use [pOR: 1.49 (95% CI 1.28–1.73)], and use of any illegal drugs (other than marijuana) [pOR: 1.45 (95% CI 1.16–1.81)]. Demographic factors associated with consumption of energy drinks included higher education, which was associated with lower odds of energy drink consumption [pORs: 0.71 (95% CI 0.56–0.91) for bachelor's degree and 0.55 (95% CI 0.40–0.74) for master's degree, compared to no bachelor's degree, respectively], and race/ethnicity [pOR: 4.43 (95% CI: 2.41–8.15) comparing African Americans to non-Hispanic white]. Conclusions Both within and across the cohorts, risky behaviors were associated with higher odds of energy drink consumption. Funding Sources This study was funded via FDA contracts and NIH grants.

In recent years, studies have often been devoted to the frequent on frequency , motives and consequences of consuming energy drinks by the student population at universities. These studies have been common in many countries. The aim of this study was to identify the patterns of energy drink consumption among college students of the Serbian University of Belgrade and to understand the attitudes, motives and consequences of consuming these beverages. The result of this study indicates that energy drink consumption is a common practice among Serbian university students (72.0% use energy drinks and 1.1% consume them regularly). Out of the total number of surveyed students 12.9% consumed energy drinks with alcohol. The most frequent negative effects in students who had used energy drinks were: weight gain (24.2%), headaches (2.6%), thirst (18.9%) and hunger (11.6%). Many of the students surveyed (62.0%) cited that their main motive for using energy drinks was improving their academic capabilities, commonly used as a way to study longer and improve mental focus. But, 10.5% of the surveyed students felt the effect of increased concentration after using energy drinks. This indicated the students' confusion and disagreement between their motives for using energy drinks and the effects achieved. A large number of surveyed students (85.3%) did not check the composition of energy drinks before consumption. The results show that students need education in this regard. This research is part of a study called "Attitudes and Behavior of Students in relation to Food and Nutrition" and is a form of preventive action to combat the widespread use of energy drinks in the student population.
