Changes in female cognitive performance after energetic drink consumption: a preliminary study

A survey of energy drinks consumption practices among student -athletes in Ghana: lessons for developing health education intervention programmes

BACKGROUND

Globally, young adults and college athletes are primary targets of the marketing campaigns of energy drink companies. Consequently, it is reported that young adults and college athletes consume energy drinks frequently. The purpose of this study was to determine the prevalence of energy drink consumption among student-athletes selected from seven public universities in Ghana. The study assessed the energy drink consumption patterns, types usually consumed, frequency of consumption and reasons why athletes consumed energy drinks.

METHODS

A total number of 180 student-athletes gave their consent to participate in the study and completed a questionnaire which was administered during an inter-university sports competition.

RESULTS

Most of the participants (62.2%) reported consuming at least one can of energy drink in a week. A high proportion (53.6%) of the respondents who drink energy drinks indicated that they did so to replenish lost energy after training or a competition. Other reasons given as to why energy drinks were consumed by the study participants included to provide energy and fluids to the body (25.9%), to improve performance (9.8%) and to reduce fatigue (5.4%).

CONCLUSION

These results suggest the need to plan health education programmes to particularly correct some wrong perceptions that athletes have regarding the benefits of energy drinks and also create awareness among student-athletes about the side effects of excessive intake of energy drinks.

Energy drinks mixed with alcohol: misconceptions, myths, and facts

Background

Whilst energy drinks improve performance and feelings of alertness, recent articles suggest that energy drink consumption combined with alcohol may reduce perception of alcohol intoxication, or lead to increased alcohol or drug use. This review discusses the available scientific evidence on the effects of mixing energy drinks with alcohol.

Methods

A literature search was performed using the keywords “energy drink and Red Bull^®” and consulting Medline/Pubmed, PsycINFO, and Embase.

Results

There is little evidence that energy drinks antagonize the behavioral effects of alcohol, and there is no consistent evidence that energy drinks alter the perceived level of intoxication of people who mix energy drinks with alcohol. No clinically relevant cardiovascular or other adverse effects have been reported for healthy subjects combining energy drinks with alcohol, although there are no long-term investigations currently available. Finally, whilst several surveys have shown associations, there is no direct evidence that coadministration of energy drinks increases alcohol consumption, or initiates drug and alcohol dependence or abuse.

Conclusion

Although some reports suggest that energy drinks lead to reduced awareness of intoxication and increased alcohol consumption, a review of the available literature shows that these views are not supported by direct or reliable scientific evidence. A personality with higher levels of risk-taking behavior may be the primary reason for increased alcohol and drug abuse per se. The coconsumption of energy drinks being one of the many expressions of that type of lifestyle and personality.

[The history, ingredients and effects of energy drinks]

The market and the degree of the consumption of energy drinks is increasing every year, but only a few have global knowledge of their ingredients and actual physiological effects. Furthermore, the number of available publications that really go into the details in this topic is also rather poor. After a short historical introduction, this article reviews the contents of energy drinks, lists a few products distributed in Hungary and abroad as a comparison, and provides information on their physical and mental effects on the human body. In the end of the article the authors word the limitations of energy drink consumption.

Consumption of energy drinks among physical education students

This descriptive and cross-sectional study aimed to characterize the pattern of energy drinks consumption in a sample of physical education students through a self-applied questionnaire (socio-demographic data and characterization of consumption). Variables associated with consumption: gender, marital status, attending gym classes, athletic swim practice, and study in the morning. Consumption pattern (n=137): 2.2% once in their lives, 9.5% at least once in the last 12 months, 38% at least once in the last month, 39.4% six times or more in the last month, 10.9% 20 times or more in the last month. Justification for consumption: 54% to improve the taste of alcoholic drinks, 27.7% to extend their evening leisure periods, 13.9% to improve sports performance, 9.5% for stimulation, 8.8% enjoy the taste, 6.6% for curiosity and 4.4% to study. Of those who consumed energy drinks, 87.6% mixed it with alcohol, and 25.9% of the students reported they consume more alcohol when it is mixed with energy drinks.

CONCLUSIONS

the consumption of energy drinks is associated to sports and drinking alcohol.
