Obstacle Negotiation Gaze Strategies Of The Physically Fatigued, Belle P. Ponce De Leon, Makena Savola, Sedona Boren, Andrew Fishman, Sarika Varma, Jacob W. Hinkel-Lipsker

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Proper obstacle negotiation while in a fatigued state is a safety concern for first responders, firefighters and other primary relief personnel in their high-risk line of work. During locomotion the central gaze is focused beyond the obstacle to plan future steps while the peripheral vision spatially tracks the obstacle. Previous work indicates that following intense exercise people experience a narrowed peripheral visual field, making them more reliant on central gaze. Thus, it is possible that when physically-fatigued people become more reliant on central gaze to perceive obstacles, leaving them unable to plan future steps as effectively.

PURPOSE: This study …

Crossing Over To The Other Side; Studying Effect Of Fatigue When Walking In A Randomized & New Space, Joshua A. Vicente, Alex X. Krause, Yesenia Acosta-Marin, Ephraim Flores, Jaesung Joo, Jacob W. Hinkel-Lipsker

International Journal of Exercise Science: Conference Proceedings

Slips, trips, and falls (STFs) that lead to a substantial amount of workplace injuries. In any career that requires physical effort, it is crucial to maintain a strong reaction and response time to these unpredictable environments to maintain worker safety. In dynamic, ever-changing workplaces, it is important to know how to best mitigate trip and fall risk. However, there is little literature describing how physical fatigue affects young, healthy individuals’ ability to negotiate obstacles, as well as whether there are worker characteristics that may put them at greater risk of STFs.

PURPOSE: Therefore, our purpose is to identify the …

Evaluating The Perspectives Of Those With Severe Physical Impairments While Learning Bci Control Of A Commercial Augmentative And Alternative Communication Paradigm, Kevin Pitt, Jonathan S. Brumberg

Department of Special Education and Communication Disorders: Faculty Publications

Augmentative and alternative communication (AAC) techniques can provide access to communication for individuals with severe physical impairments. Brain–computer interface (BCI) access techniques may serve alongside existing AAC access methods to provide communication device control. However, there is limited information available about how individual perspectives change with motor-based BCI-AAC learning. Four individuals with ALS completed 12 BCI-AAC training sessions in which they made letter selections during an automatic row-column scanning pattern via a motor-based BCI-AAC. Recurring measures were taken before and after each BCI-AAC training session to evaluate changes associated with BCI-AAC performance, and included measures of fatigue, frustration, mental effort, …

Stress Management For Student-Athletes: Stress Levels And Mitigation Strategies For Athletes And Coaches At A Faith-Based University, Caleb Herman

Master of Education Program Theses

Research demonstrates that college is a stressful time of life, especially for student-athletes who are involved in both athletics and academics (Lopes Dos Santos et al., 2020). While research exists that proposes strategies for helping either students or athletes cope with the stress that they face, very little research specifically addresses the needs of student-athletes. The purpose of this study was to determine effective ways in which coaches can mitigate stress for student-athletes at faith-based universities. Through a measurement of the anxiety and depression levels that student-athletes at Dordt University experience, correlations were made between exhaustion levels, a reduced sense …

Paraspinal Muscle Fatigue Influences Trunk Kinematics During Single-Leg Drop Jump Landings, Natalie A. Delgadillo, Michael W. Olson

International Journal of Exercise Science: Conference Proceedings

Neuromuscular fatigue of the paraspinal muscles modifies kinematics responses to perturbations in controlled settings. PURPOSE: The purpose of this study was to assess trunk kinematics response during single-leg drop landings before and after induced neuromuscular fatigue of the low back muscles. METHODS: 13 male and female volunteers (22.3 ± 2.6 years, 1.66 ± 0.09m, 68.0 ± 14.0 kg) performed single-leg drop landings with their preferred leg from a 30 cm height before and after induced neuromuscular fatigue of the trunk. 3-D analysis of the trunk kinematics was performed using reflective spheres of 14 mm diameter. Maximum voluntary isometric contractions (MVIC) …

Shooting Accuracy And Precision After Tactical Exercises Among Special Weapons And Tactic (Swat) Team Members, Kristina M. Woodford, Monica V. Kock, Jacob D. Fanno, Heather E. Webb

International Journal of Exercise Science: Conference Proceedings

Law enforcement is one of the most stressful occupations and investigations have demonstrated law enforcement officers (LEOs) have greater CVD-related morbidity and mortality than the general population. LEOs are chronically exposed to events including physical dangers and psychological stress. Every day, LEOs utilize their training to save lives and keep themselves and their communities safe, however, Special Weapons and Tactics (SWAT) teams have duties that are beyond the scope of normal law enforcement personnel. Part of this training includes the use of firearms to prepare officers to protect themselves and others in highly dangerous situations. Engaging in these dangerous situations …
