Acute Consumption of 4D Dietary Supplement vs. Placebo: Effects on Perceptual-Cognitive and Visual-Motor Performance

Multi-ingredient supplements (MIS) have been reported to positively impact various aspects of performance. While caffeine alone has been shown to improve aerobic performance, resistance training (such as bench press), reaction time and sprint performance, it has also been suggested that it lacks the ability to improve cognition. Therefore, the purpose of this investigation is to examine the effects of a caffeine containing MIS on measures of cognition and reaction time, with the intent of providing additional benefits to athletic performance.

This study will utilize a randomized, double-blind, placebo-controlled design. Following two familiarization trials, participants will complete two testing visits. During these visits, they will complete baseline assessments, consume either the 4D dietary supplement or a taste matched placebo, and rest for 45 minutes. Reaction time, cognition assessments (visual tracking speed), and reactive agility performance will be assessed following the rest period.
