Abstract
Abstract
Introduction: The purpose of this study was to determine the effects of an energy drink (JOCKO GO) on mood, sustained attention/reaction time, and hand steadiness.
Methods: A total of 29 active men (n = 9) and women (n=20) (mean ± SD: age 22 ± 5 yr.; height 168±8 cm; body mass 68.2 ± 12.8 kg; lean body mass 51.9 ± 15.0 kg; fat mass 15.4 ± 6.8 kg; percent body fat 22.6 ± 8.9%; total body water 38.6 ± 8.6 liters) completed this randomized, crossover, counterbalanced trial. Each subject consumed either one can (355 ml) of the energy drink or nothing (i.e., control condition). Each assessment (Profile of Mood States, Psychomotor Vigilance Test, and Hole Type Steadiness Tester) was made 30-60 minutes after consuming the energy drink, whereas, in the control condition, assessments were made 30-60 minutes after arrival to the clinical site.
Results: There were no statistically significant differences for any of the measures.
Conclusions: This particular energy drink at the dose provided does not affect sustained attention, mood, or hand steadiness.
