Summary
- Statement of the research question:
Does the caffeine in energy drinks interact with other ingredients to affect cardiovascular function in healthy male and female adults after exercise?
2. Purpose and significance of the study:
Energy drinks are beverages promoted to enhance alertness along with athletic and cognitive performance. The most common ingredients found in energy drinks include water, sugar, caffeine, taurine, and B-vitamins, with variable inclusion of other ingredients, such as carnitine, glucuronolactone, inositol, guarana, ginkgo biloba leaf extract, thistle extract, and ginseng root extract. Since the mid-1990s, the consumption of energy drinks has grown dramatically, with worldwide sales in 2017 exceeding $49 billion.
As the sale of energy drinks has grown, so has the number of adverse event case reports for patients who consumed energy drinks. Reported symptoms included cardiac arrhythmias such as ventricular fibrillation, atrial fibrillation, and cardiac arrest. A few small clinical studies have found that energy drinks can increase systolic and diastolic blood pressure and change electrical activity in the heart as measured by an electrocardiogram (ECG). The intent of the proposed study is to determine whether caffeine or the combination of caffeine with taurine and L-carnitine can alter cardiovascular function. Hypothesis: The effects of the ingredients of energy drinks on the heart are mediated in part by interactions between caffeine, taurine and carnitine. The amount of each ingredient in the study was based upon the amount commonly contained in two cans of energy drinks currently on the market.
Description
Title: The Effect of Energy Drink Ingredients on Cardiovascular Function
- Statement of the research question
Does the caffeine in energy drinks interact with other ingredients to affect cardiovascular function, including QTc interval of the EKG, heart rate and blood pressure in healthy male and female adults after exercise?

The intent of the proposed study is to determine whether caffeine or the combination of caffeine with taurine and L-carnitine can alter heart rate, blood pressure and the QTc interval of the EKG. Caffeine stimulates cardiovascular function primarily through antagonism of adenosine receptors. Taurine is a modulator of intracellular calcium ion concentrations which can affect the strength cardiac contraction. Carnitine facilitates fatty acid transport into the mitochondria, thereby increasing the production of adenosine triphosphate, the energy source of cells. Hypothesis: the effects of the ingredients of energy drinks on the heart are mediated in part by interactions between caffeine, taurine and carnitine. The amount of each ingredient in the study was based upon the amount commonly contained in two cans of energy drinks currently on the market.
