Study Overview
Brief Summary
The objective of this protocol is to investigate the effect of consumption of a commercially available energy drink beverage on blood pressure, heart rate, and energy metabolism
Detailed Description
Energy drink consumption has gained a lot in popularity and represents one of the most rapidly growing segments of the beverage industry. While regularly discussed in media outlets etc. the cardiovascular effects are not well described or well known. For example, the impacts on various cardiovascular parameters range from improved, decreased, to not impacted at all depending on the source. This can be due to a number of reasons including, study protocol design, study population tested, energy drink product used, volume consumed, etc. Accordingly, this study aims to investigate the impact of acute consumption of a standard commercially available can of energy drink beverage on the following parameters.
- Arterial blood pressure
- Heart rate
- Energy metabolism (oxygen consumption and carbon dioxide production
It is hypothesized that consumption of a 12 oz energy drink will result in modest elevations in arterial blood pressure, heart rate, and energy metabolism relative to when consuming of an equal volume of water.

Outcomes
Primary Outcomes
Oxygen consumption milliliters per kilogram of body weight per minute
Time Frame: baseline & 30, 60, 90, 120 min following beverage consumption
This will be assessed using a metabolic cart to measure the amount of oxygen that is consumed by the body.
Heart rate in beats per minute
Time Frame: baseline & 30, 60, 90, 120 min following beverage consumption
Heart will be measured using an electrocardiogram procedures that are done in a doctors office.
Peripheral blood pressure in millimeters of mercury
Time Frame: baseline & 30, 60, 90, 120 min following beverage consumption
blood pressure will be measured on the upper arm using standard procedures that are done in a doctors office.
Secondary Outcomes
No secondary outcomes reported
