Dose Response Effects Of A Caffeine-containing Energy Drink On Muscle Performance: A Repeated Measures Design
Notes for this study:
|Number of Subjects
In 12 active and healthy participants (light caffeine consumers at less than 60mg daily), an intake of a caffeinated energy drink (compared to placebo, the same energy drink but not caffeinated) was able to increased blood pressure and heart rate at rest without significantl affecting metabolic rate up to 3mg/kg bodyweight.
Power output, as measured by half-squat and bench, was increased only at 3mg/kg bodyweight with no significant influence at 1mg/kg.
