Post-Exercise Cardiovascular Responses Following Energy Drink Consumption

Summary

The purpose of this study is to determine the effects of consuming an original flavor energy drink on electrocardiographic (ECG) and hemodynamic responses during and after exercise in healthy subjects. The effect of drinking an energy drink on exercise performance will also be evaluated.

Energy Drink

Participants will consume a randomly assigned single 24 oz can of an original flavor energy drink within a 30-minute period. Baseline ECG, HR, BP, blood sample and body weight will be obtained. Then perform a continuous, progressive treadmill or bicycle ergometry test until volitional exhaustion. ECG will be monitored continuously during exercise, rating of perceived exertion (RPE) will be recorded every minute of each workload increase. After completion of exercise, subject will remain standing on treadmill (or seated on ergometer) for 10 minutes while ECG, BP, HR and blood samples are obtained. Subsequent ECG measures will be obtained at 1,4,7 and 10 minutes. After 10 minutes, the subjects will be free to sit, stand or move quietly in the lab. During the 2-hour post exercise monitoring period, subject's ECG, HR, BP will be recorded at 30-minute intervals. Blood samples will be collected immediate upon cessation of exercise, at 1 and 2 hours post exercise

Placebo-control

Participants will consume a randomly assigned single 24 oz can of control drink within a 30-minute period. Baseline ECG, HR, BP, blood sample and body weight will be obtained. Then perform a continuous, progressive treadmill or bicycle ergometry test until volitional exhaustion. ECG will be monitored continuously during exercise, rating of perceived exertion (RPE) will be recorded every minute of each workload increase. After completion of exercise, subject will remain standing on treadmill (or seated on ergometer) for 10 minutes while ECG, BP, HR and blood samples are obtained. Subsequent ECG measures will be obtained at 1,4,7 and 10 minutes. After 10 minutes, the subjects will be free to sit, stand or move quietly in the lab. During the 2-hour post exercise monitoring period, subject's ECG, HR, BP will be recorded at 30-minute intervals. Blood samples will be collected immediate upon cessation of exercise, at 1 and 2 hours post exercise
