Energy drinks (EDs) and energy shots (ES) have become popular because they are purported to promote vitality, energy, and enhanced physical performance. PURPOSE: The purpose of this study was to assess the effect of a commercial energy shot on hand steadiness and reaction time. METHODS: Following IRB approval, 14 college-aged males and 18 females were tested for hand steadiness by holding a stylus in three descending diameter holes (7.92mm, 4.75mm, 2.77mm) for 20s each with a 30s rest between sets. Frequency of stylus to edge hits were measured and recorded. Reaction time was measured using a computerized program. The task included pressing the mouse button at the instance a light switched from red to green. Five trials of five repetitions were given to each subject. Following pre-testing subjects were randomly divided into an experimental group and a control group. The experimental group was given a commercial ES (57 ml) and the control was given a placebo. Following 30 min of inactive resting subjects were tested again. RESULTS: One way ANOVAs indicated that the ES group scored significantly (ppCONCLUSION: It is possible that reaction time improvement could be beneficial in sports that require quick, reflexive movement. However, the potential adverse psychological and physiological effects warrant discretionary use of such products.
