No “Jitters” But No Energy From A Commercially Available Energy Drink., Jose Antonio, Jason M. Curtis

Journal for Sports Neuroscience

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 …

Based on review and critical analysis of the literature regarding the contents and physiological effects of coffee related to physical and cognitive performance conducted by experts in the field and selected members of the International Society of Sports Nutrition (ISSN), the following conclusions represent the official Position of the Society:

(1) Coffee is a complex matrix of hundreds of compounds. These are consumed with broad variability based upon serving size, bean type (e.g. common Arabica vs. Robusta), and brew method (water temperature, roasting method, grind size, time, and equipment).

(2) Coffee’s constituents, including but not limited to caffeine, have neuromuscular, …

The Effects Of A Multi-Ingredient Supplement On Various Cognitive Measures, Jason M. Curtis, Cassandra Evans, Veronica Mekhail, Paulina Czartoryski, Juan Carlos Santana, Jose Antonio

Journal for Sports Neuroscience

The purpose of this study was to investigate the effects of a multi-ingredient pre-workout supplement (MIPS) on mental and physical performance. Seventeen exercise-trained men (n = 7) and women (n=10) completed this randomized, placebo-controlled, double-blind, counterbalanced, crossover trial. Participants consumed either a multi-ingredient pre-workout supplement (MIPS) or a placebo in a randomized, counterbalanced order. Forty-five minutes post-consumption, the following assessments were conducted: psychomotor vigilance test (PVT), Profile of Mood States (POMS), Stroop test, vertical jump test, and a Cold pressor test. There was a one-week washout period between assessments. There were significant differences in the incongruent task for the Stroop …

Current State Of Sleep-Related Performance Optimization Interventions For The E-Sports Industry, Allison Joy Brager, Guido Simonelli

Journal for Sports Neuroscience

Abstract: The e-sports industry is rapidly expanding but despite industry growth, there are existing gaps in knowledge regarding holistic and pharmacological performance enhancement strategies. The current commentary focuses on the current state of performance intervention strategies that target sleep/wake and circadian timing systems. These performance intervention strategies are based on the current state of sleep/wake health and research portfolios of Army research laboratories. The intent is to provide a foundation for future research efforts directly targeting sleep/wake and circadian timing systems in order to optimize and enhance e-sports performance at both the individual and group levels.

Effects Of Pre-Workout Supplements On Strength, Endurance, And Mood, Anya C. Ellerbroek, Jose Antonio

Internet Journal of Allied Health Sciences and Practice

Purpose: The purpose of this pilot study was to assess the acute effects of consuming pre-workout supplements on indices of muscular strength, endurance and mood states.

Methods: In a double- blind, placebo-controlled, randomized crossover design, fourteen moderate to highly-trained recreational athletes (7 female, 7 male) participated in this investigation. Subjects came to the lab twice between testing sessions. They consumed either pre supplement (mixed with 8 to 12 ounces of water) or placebo 30-minutes prior to testing. The pre-workout supplement combination (Athelite Nutrition Inc.) contained 15.62 grams per serving, 25 kcals, that consisted of a proprietary blend including caffeine (as …
