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 …

Post-Activation Performance Enhancement Through Variable Loading Maintains Power Output Over Five Sets In Highly Trained Athletes, Robert Rocanelli, Morgan Siegel, Pedro Yunes, Pete Bommarito, Monique Mokha

Journal for Sports Neuroscience

The goal was to examine the acute effects of five sets of variable loading (VL) on the post-activation performance enhancement (PAPE) response during a live training session in highly trained athletes. PAPE is the phenomenon where acute improvements in power production in light loaded movements occur post near maximal loaded muscle contraction. PAPE may be induced with VL where resistance in the form of chains or bands is added to the bar as it displaces in the concentric phase. Participants were American football players from a variety of field positions (n=12, height =188 ± 0.01 cm, total body mass = …

Pilot Testing Of A Non-Gaming Cognitive Battery In Expert Esports Athletes, Allison J. Brager, Patrick Belling, Jason Sada, Jeffrey Osgood, Bradley Fawver, Michael Dretsch

Journal for Sports Neuroscience

Introduction: The esports industry is rapidly expanding, making it imperative to identify common data elements of expert gamers for the purposes of performance optimization and enhancement. We aimed to measure cognitive performance in a convenient sample of expert esports athletes, as well as to determine if cognitive performance of these individuals could be further enhanced through a novel non-gaming neurocognitive test battery.

Methods: Elite esports athletes (n = 5) participated in a four-day cognitive and strength & conditioning program at the Sports Academy (Thousand Oaks, CA). Cognitive performance was assessed through five tasks of increasing cognitive load. Baseline …

Using Neural Signals To Investigate Athlete Burnout, Mathew R. Hammerstrom, Thomas D. Ferguson, Hendrik L. Pepler, Anthony Pluta, Gordon Binsted, Olave Krigolson

Journal for Sports Neuroscience

Objective: In the present study, we examined the relationships between athlete burnout, brain function, and self-assessment of performance, and how these relationships can be quantified using mobile electroencephalography (mEEG). Specifically, we performed this study to determine whether mEEG can be utilized as an objective measure of athlete burnout. In addition, we sought to determine whether there was any relationship between athlete burnout and athlete self-assessment of performance while controlling for our neural results.

Methods: We tested these relationships in a sample of high-performance athletes – whereby we had athletes complete an mEEG assessment and also had the athletes complete a …

Examining Movement-Specific Reinvestment And The Yips In Professional Baseball, Lazaro Gutierrez Mba, Ma, Phd, Pradeep R. Vanguri Phd, Lat, Atc

Journal for Sports Neuroscience

The sudden inability of a professional baseball player to throw the baseball accurately, a condition known as the “yips”, is considered a motor movement disruption. Movement-specific reinvestment, including movement self-consciousness (MS-C) and conscious motor processing (CMP), explains the disruption of well-learned motor movements in different performance domains such as throwing. The purpose of this quantitative, causal-comparative study is to examine movement-specific reinvestment level differences between self-reported yips-afflicted and non-afflicted professional baseball players in the United States as measured by the Movement Specific Reinvestment Scale (MSRS). A total of 130 professional baseball players (65 yips-afflicted and 65 non-afflicted) participated in the …

The Effects Of Joint Angle And Anchoring Scheme On Performance Fatigability And Neuromuscular Responses Following Isometric Forearm Flexion Tasks To Failure, Jocelyn E. Arnett, Robert W. Smith, Tyler J. Neltner, John Paul V. Anders, Dolores G. Ortega, Terry J. Housh, Richard J. Schmidt, Glen O. Johnson

Journal for Sports Neuroscience

Purpose: The purpose of this study was to examine the effects of joint angle on MVIC and neuromuscular responses at task failure following sustained, isometric forearm flexion tasks anchored to a rating of perceived exertion (RPE) of 8 (RPE = 8) and anchored to the initial torque that corresponded to RPE = 8 (TRQ). Methods: Ten women (age: 21.0 ± 2.8 yrs; height: 168.5 ± 7.2 cm; body mass: 68.0 ± 7.2 kg) performed 2, 3 s MVICs at joint angles (JA) of 75°, 100°, and 125° (randomized order) before and after sustained, isometric forearm flexion tasks to failure at …

Sex-Specific Effects Of High-Fat And Ketogenic Diet On Inflammatory Responses In The Hippocampus, Shalet James

Honors Theses

Poor diet and metabolic diseases (obesity, Type 2 diabetes) are associated with increased risk of neurodegenerative and neuropsychiatric disorders, including Alzheimer’s disease, anxiety, and depression. Studies indicate that inflammation in the hippocampus could be one mechanism linking these conditions. Previous findings on inflammation, specifically glial activity in response to a high-fat diet, indicate sex differences in microglial responses in the hippocampus. The ketogenic diet is characterized by a high-fat, low-carbohydrate, and moderate-protein diet. While the ketogenic diet is very high in fat content, it may also possess neuroprotective properties against brain aging and neurodegenerative disorders, as well as boost mood …
